serum separation tubes with gel       The gel serum separating tube is a test tube commonly used in clinical blood centers. The inside of the tube is mainly added with separating gel, but sometimes other reagents are added for common use, such as coagulants. Due to the high-quality finished tubes appearing in front of everyone during the blood drawing process and being used directly, it is difficult for the naked eye to detect their presence inside the tubes, which is also a detail that many novice operators in hospitals tend to overlook. They don't know how to use this gel serum separation tube, so the following details will be introduced to you.       1、 Reagent addition of gel serum separation tube       When the gel in the tube is in full contact with the blood, it can separate the blood and completely separate the serum from the blood clot. If it is used together with the coagulant, the separation speed will be faster to ensure that the test results will not be biased. Generally, the separated gel does not need to be prepared and directly added to the test tube, while the coagulant is in the form of powder. If it needs to be used, it needs to be prepared into a solution, and then sprayed on the inner wall of the test tube for drying.   Serum separating gel       2、 Use of gel serum separating tube       After the blood collection of the separation tube is completed, the user should pay attention to slowly rotating the test tube about 5 times, and the amplitude of the movement should not be too large, so that it can come into uniform contact with the reagent. Then let it stand for about half an hour, wait for the blood sample to completely coagulate, and then put it into a centrifuge for operation. At this time, the centrifugation speed and time need to be controlled. If the centrifugation rate and time are not properly controlled, the separation of gel will not work. If it cannot be overturned, it will cause hemolysis when the blood sample is mixed with gel.       3、 Problems of gel serum separating tube       In reality, due to the lack of experience of many clinical staff, the use of gel serum separation tube in the actual operation process led to the blockage of the analytical instrument caused by fibrin residues in the serum. If the condition of complete blood coagulation is excluded, it is related to the quality of gel. Although there are many businesses selling separation gel, there are still many inferior products, so we must pay attention to them when choosing. If the experimental process is very smooth, wait for the serum to be completely separated, let it stand for a few minutes, and then use the machine for testing and analysis. It cannot be immediately taken out for use, otherwise it will also cause poor testing results.       Desheng is a professional supplier of serum separation gel in China. The separation gel has accurate specific gravity and good overturning performance. In case of any problem, it will be answered comprehensively. Currently, we have signed contracts with over 1000 customers both domestically and internationally for long-term supply.

Principle and operating points of serum separator gel tube       In the early stages, most hospitals would wait for the blood to naturally coagulate after blood collection, and then undergo centrifugation. This process not only took a long time, but also affected the functionality of various analytical instruments. In order to rapidly promote the development of detection technology and effectively improve efficiency, blood sampling additives have gradually emerged, such as separation gel, coagulant, anticoagulant, etc. Among them, the use of serum separation gel tube has become an indispensable product in the clinical laboratory. As an important guarantee for the quality of routine blood collection, it not only reduces the difference of detection results, but also effectively avoids various blood cross infections, and prepares high-quality serum samples. Here we will analyze the serum separation gel tube.       1、 Principle of separating serum and blood clot by serum separating gel       As a hydrophobic organic compound, its appearance is a viscous colloid with thixotropic properties. Because its structure contains hydrogen bonds, it can form a network structure through association, and then the network structure is destroyed under the action of centrifugal force. After the centrifugal force disappears, it returns to the original colloidal appearance due to thixotropy. Generally, the specific gravity of the separated gel is about 1.045, while the specific gravity of the serum is 1.02, and the blood clot is 1.08. When the blood sample is collected by using the separated gel tube, it will quickly turn over under the action of centrifugal force, forming three parts of serum, separated gel, and blood clot in the tube, so that medical personnel can achieve the purpose of serum extraction or detection from the original tube.   serum separator gel tube       2、 Gel procoagulant tube for serum separation       The separating gel tube contains not only separating gel, but also accelerating agent, which is also added in clinic to quickly separate and promote blood coagulation. After processing, it is sprayed into the separating gel tube. Due to the fact that blood can only be centrifuged on the machine after complete coagulation, the use of coagulants can accelerate the blood coagulation time and ensure the stability of blood coagulation, without causing fibrin to be mixed in the isolation layer.      3、 Key points of operation of gel tube for serum separation       1. During the process of centrifugation on the machine, attention should be paid to the control of speed and time. Generally, centrifugation at 3000r/min for about 5 minutes is sufficient.       2. After collecting blood samples with gel tube, slowly rotate the test tube for about 5 times as soon as possible, place the blood sample for about half an hour, and then separate it after the blood is completely coagulated.       3. Blood separation or serum testing can be achieved on the original tube without transfer. If transfer is required, attention should be paid to using sterile matching test cups for examination.       As a professional manufacturer of serum separation gel, Desheng has 18 years of R&D and production experience and strong strength. It supplies many enterprises in China. Due to its independent factory line and warehouse, it can meet the needs of large-scale ordering and shipping.

serum separator tube gel name       In recent years, with the rapid development of medical testing technology, the application of serum separation tubes has become increasingly common, and even become an indispensable item in medical research and clinical testing. The reason why it is so valued is mainly because it can quickly and effectively separate the serum in the blood sample, facilitating subsequent research and diagnosis.       1、 Name of gel in serum separating tube       There are generally two kinds of materials for serum separation tubes, plastic tubes and glass tubes. A layer of separation gel will be added to the tubes made of these two different materials. It is also known as the "serum separation gel", which can efficiently isolate serum and blood clots in the blood, allowing serum to accumulate separately above the separation gel, making it convenient for medical staff to sample and test.       2、 Applicable inspection items for serum separation tube       The serum separation tube is suitable for various clinical examinations, such as routine blood analysis, liver and kidney function tests, serological tests, and enzymatic tests. Because the serum separation gel it contains can effectively obtain serum samples with high purity and no interfering impurities, which can fully ensure the accuracy and reliability of experimental results.         3、 Principle of action of serum separation tube       Its working principle is achieved by relying on the substance serum separation gel, which can quickly separate blood through its own chemical properties, such as specific gravity, viscosity, physiological inertness, etc. At the same time, due to the external centrifugal force, it will flip to the center of the serum and blood clots, preventing them from exchanging substances and ensuring the stability of serum components and plasma.       4、 Precautions for using serum separation tubes       Although the use of serum separation tubes is relatively simple, in order to ensure the accuracy of experimental results, some issues still need to be noted:       1. The samples in the serum separation tube need to be stored in a standardized manner, and the separation and testing should be completed within the established time frame. Do not leave them in a high temperature environment for a long time. Usually, the suitable storage temperature for separated serum is between 2-8 degrees Celsius, and the storage time should not exceed 24 hours.       2. Before use, it is necessary to check whether the separation tube is damaged and whether the separation adhesive inside is mixed with unknown impurities. If there are any abnormalities, it should be replaced immediately and cannot be used again. Pay attention to the setting of centrifugation time and centrifugation speed during the centrifugation process.       As a manufacturer of serum separation gel in China, Desheng not only has 18 years of professional research and development experience, but also has stable performance of separation gel products, which can be used in various clinical experiments without any interference.

stacking gel separating gel difference       As a polymer, separation adhesive has undergone several generations of changes and upgrades since its emergence, and its key performance has also been qualitatively improved in various aspects. However, due to the differences in raw materials and production methods used by manufacturers, several different types of separation adhesives may appear, such as commonly used separation adhesives with acrylic acid, resin, and silicone rubber systems. Recently, there has been the emergence of concentrated glue again. What substance is it? What is the difference between it and the separation adhesive?       1、 What is concentrated adhesive?       It mainly refers to that in discontinuous polyacrylamide gel electrophoresis, the gel concentration as the same medium will be divided into two types, namely, the negative electrode concentration is 2% - 5%, and the remaining concentration is 6% - 8% as the separation gel.   Barreled serum separation gel       2、 The difference between concentrated adhesive and separated adhesive       1. Differences in nature       From the performance of concentrated gel, it can be seen that it is a part of discontinuous polyacrylamide gel electrophoresis, while the separating gel is a part of polyacrylamide gel in discontinuous buffer system. Its composition, pH value and gel pore size are significantly different from those of concentrated gel.       2. Differences in reaction processes       The reaction process of concentrated gel is obviously different from that of separation gel. Because the former has low gel concentration and larger pore diameter than that of separation gel, the resistance of charged protein or nucleic acid ion gel is small and the movement speed is fast. Once it is close to the small pore gel, the resistance becomes larger and the speed slows, which will concentrate the sample. However, the separation gel has high concentration and small pore size. Due to the role of molecular sieve, small molecular substances are easy to pass through, with small resistance and fast moving speed. At this time, they will be separated from gel by molecular sieve effect according to the difference of molecular weight.       3. Differential effects       Based on the performance of both, it can be clearly known that the concentrated gel has the function of reducing the resistance of ion movement and has the function of stacking, which can concentrate the diluted sample into a relatively tight state. At the same time, it also has stability, allowing proteins to aggregate at the moving interface, concentrate into intermediate blocks, and stabilize the entire reaction interface. The separation gel has many functions, the most important of which is prepared by the manufacturer. It can be added as an additive to vacuum test tubes to separate blood, ensuring the stability of serum components, and providing accurate and accurate data results for medical staff.       As a professional manufacturer of serum separation gel in China, Desheng not only has 18 years of research and development experience, but also has an independent production line that can produce in bulk according to customer needs.

what is serum separator gel made of       As a chemically inert polymer, the serum separation gel exists in the form of a viscous colloid, with a key specific gravity between 1.045-1.065g/cm3, just between the serum and the blood clot. Then, through centrifugation, it can be flipped to the center of the blood collection vessel, completely separating the serum and blood clots, thereby quickly and efficiently extracting the serum sample. However, there are many types of separated gel on the market, and the composition and production of each type are different. What is it made of? Below is a detailed introduction for everyone.       1、 Polysiloxane separation gel       This type of separation gel is mainly made of SiO ₂, polysiloxane, diluent and other additives. Among them, polysiloxane is the key, occupying a content between 80% -90%, with SiO2 added at around 10% -15%, and diluents and other additives at around 2%. Although this kind of separation gel is sold on the market, hemolysis often occurs in experiments due to unstable performance, and there are not many users in general.   Serum separating gel       2、 Acrylate separation gel       It is mainly made of fumed silica, polyacrylate, and additives, with polyacrylate as the main content, accounting for about 96%, fumed silica is about 3%, and other additives are about 1%. Compared with the preparation of the first separation gel, the performance of this acrylic acid separation gel has been further improved. Because it contains acrylate, it will not appear water absorption and swelling, and has good wire drawing property. This is a separation gel that is widely used in the market, and also a product widely selected by the public.       3、 Resin separation gel       This is a new generation of research and development product, mainly made of straight chain alkane resin. Compared with the first two, it has stronger physiological inertness, not only resistance to hydrolysis and irradiation, but also improved reagent compatibility. Since the raw material price of straight chain alkane resin is high and the production cost is high, the price is slightly more expensive than other types of separation gel, which is generally suitable for high specification blood collection experiments, such as PRP tubes in the medical and aesthetic field.       The types of serum separation gel are different, and their manufacture is also different. When using, we must choose products with high cost performance and reliable quality according to the experimental requirements. As a manufacturer specializing in the production of serum separation gel, Desheng Biochemical has developed in China for 18 years. It is equipped with a senior research and development team. The separation gel has high production efficiency and sufficient stock. Because it is delivered directly by the manufacturer, the price is favorable.

serum separator gel composition       In clinical blood detection, blood collection vessel is a container widely used for blood sample collection. Because of its internal separation gel composition that can accommodate and separate serum and plasma, it is the preferred product of major medical institutions. In addition, because of the special gravity of serum separation gel, it can not only effectively separate serum and plasma, but also complete the preservation and transportation of blood samples to prevent secondary infection accidents of blood samples. Since it is a substance widely recognized and used in medicine, let's focus on taking you to a specific understanding.       1、 What is the serum separation gel composition?       In fact, it is a network structure composed of a large number of hydrogen bonds, appearing in the form of a transparent or semi transparent viscous colloid in front of everyone. Many manufacturers will accurately control their specific gravity, physiological inertia, viscosity and thixotropy during research and development, so that they can quickly and smoothly separate serum and plasma after contacting with blood, ensuring the stability of their components and the accuracy of experimental results.   serum separation gel       2、 Working principle of serum separation gel composition       Its working principle is that the specific gravity of the separated gel is 1.05, the serum is 1.02, and the blood clot is about 1.08. When it is centrifuged in the same blood collection vessel with the coagulated blood sample, the centrifugal force will cause changes in the hydrogen bond structure. At this time, the viscosity of the separated gel will also become lower, so that the blood clot can be transferred to the bottom of the tube, and the separated gel will turn over, forming three parts in the tube: serum, separated gel, and blood clot, so as to help medical personnel extract high-quality serum or plasma samples for testing.       3、 Where can I buy serum separation gel?       Although there are many businesses selling serum separation gel on the market, it is still necessary to choose carefully if you want to buy reagents with reliable quality and stable performance. As a manufacturer specializing in the production of serum separation gel, Desheng has experienced several decades of development. It has made continuous breakthroughs from the first generation of separation gel to the fifth generation of separation gel, and has further improved its key performance. At the same time, it has brought new products with excellent quality to the market. If you want to purchase, you can make it your preferred target.       As a direct selling manufacturer of serum separation gel in China, Desheng Company has independent plant and production equipment, and can supply a large number of goods at a preferential price at any time.

Key characteristics and preparation of serum separator gel         The serum separation gel is used in the vacuum blood collection tube. It is mainly the isolation material for the preparation of serum or plasma test samples. It can use its excellent performance to form a barrier between serum and plasma to prevent their material exchange, so as to achieve sample stability and facilitate the preservation and accuracy of test results.       1、 Key characteristics of serum separation gel       1. The surface of the precipitated serum sample is free of oil droplets and other precipitates, and long-term use will not block the sampling needle.       2. There is no wall climbing phenomenon. The separated gel is added to the test tube, and there is no wall hanging after being placed for a period of time.       3. It has physiological inertia and can minimize interference with experimental specimens.       4. Stable performance, less prone to aging, and stable memory storage for 2 years, without affecting the separation effect.       5. Equipped with radiation resistance, the irradiation dose can withstand the range of 8-25KG, and other properties will not change after radiation resistance.       6. There will be no backflow during transportation and storage.   Serum separating gel       2、 Preparation of serum separation gel       1. Add a 50% mass ratio mixture of butyl methacrylate, 2-mercaptoethanol, and 0.6 parts BPO of methyl methacrylate to a flask;       2. Stir and heat up. When the temperature reaches 85 ° C, a monomer mixture containing 0.6 parts of BPO butyl acrylate and additive mixed acid fat in the residue is dropped from the dropper funnel into the reaction flask, maintained at 85 ° C, and the monomer is dropped out within 3 hours; After continuing the reaction for 1 hour, cool to below 70 ° C to obtain an acrylic copolymer solution;       3. After 2 hours of vacuum distillation of the solution, remove the solvent toluene and unreacted monomers to obtain a polyacrylate solution;       4. Add 5 parts of hydrophobic silica gel to the polyacrylate solution, stir, and then vacuum defoaming to obtain the product serum separation gel.       Since the preparation of serum separation gel involves many fields, its technical content and production requirements are very high. The above method is the simplest and convenient one, but it is not applicable to all research and development, and should be adjusted according to its own requirements.   Barreled serum separation gel       3、 Precautions for use of separation gel       The reason why we talk about the use of serum separation gel is that it directly represents the quality of the separation results. The following two points are the most important points for attention, which should be paid attention to:       1. First of all, the quality of the separated gel should be emphatically investigated before use. Its specific gravity should be 1.045-1.065g/cm3, between serum and blood cells. Otherwise, it is not easy to turn over, resulting in poor quality of the extracted serum sample.       2. The use of centrifugation should be separated after the blood has completely coagulated, otherwise there is a tendency for fibrin to be mixed in the isolation layer, leading to hemolysis.       As the main supplier of serum separation gel, Desheng has always been leading other brands in the Chinese market. Its product performance is stable, and all key indicators are accurately controlled. The batch products produced are supervised and tested by professional quality departments, and it never sells fake and inferior separation gel.

Introduction to the performance and advantages of the serial separation gel       In recent years, serum separation gel has been indispensable in clinical blood testing. Its use as an additive in vacuum tubes has an undeniable effect, not only ensuring the accuracy of blood testing results, but also saving waiting time for medical staff and patients. Since it is an important additive, it is important for everyone to have an understanding of it during use, otherwise it may lead to unnecessary troubles, such as hemolysis, wall hanging, poor flipping, etc. Let's introduce it in detail below.       1、 What is serum separation gel?       As a high molecular compound, it is physiologically inert, insoluble in water, and has a large number of hydrogen bonds in its structure, which has good thixotropy and separation properties. Driven by centrifugal force, the reticular structure is destroyed, but it can be gathered together again in a short time due to thixotropy, thus isolating the blood. It is often used to separate serum and blood clots in yellow vacuum tubes.       2、 Is the performance of serum separation gel up to standard?       The measurement of whether the performance meets the standard mainly depends on the control of key numerical values such as appearance, specific gravity, and viscosity. Although many manufacturers produce serum separation gel in the market, the basic requirement for specific gravity is between 1.045 and 1.065g/cm3, because this is the only way to effectively separate blood. The appearance requirements are different, usually transparent, semi transparent, or opaque, without any impurities, and the viscosity needs to be maintained between 100000 to 300000 kPa, which is easy to add and thixotropic.   Barreled serum separation gel       3、 What are the other advantages of serum separation gel?       1. Hydrolysis resistance     At present, most of the separation adhesives used are acrylic and resin systems, which are hydrophobic materials with hydrolysis resistance. When in long-term contact with water or other reagents, there will be no reaction changes, so to some extent, the original properties of blood are guaranteed, which is conducive to the accuracy of detection results.       2. Radiation resistance     Because it is used in vacuum blood collection vessels, the basic requirement is to ensure that the collected blood components are not damaged. If there are bacteria in the tube, it will definitely interfere with the test results. Therefore, many manufacturers will carry out radiation resistance treatment. Generally, the separation gel with radiation resistance is not prone to aging, and the entire blood operation is carried out in a sterile environment, avoiding the occurrence of cross infection.         As a manufacturer of serum separation gel in China, Desheng has 18 years of research and development experience. Its product performance is not only stable and reliable, but also affordable. We have professional staff to receive every customer, ensuring one-on-one handling and coordination of subsequent problems.

serum gel separator tube       The serum gel separating tube is often used in the blood test center. Its main function is to separate the serum in the blood sample, facilitate the subsequent research and experiment, and help medical staff effectively judge the abnormality of the patient's body. However, it is not possible to separate serum with just one test tube, and it is necessary to rely on the serum separation gel in the test tube to achieve the goal. Why can the separation gel tube be used for blood separation? Let's talk about it in detail below.       1、 Serum separation gel       In fact, it is a kind of high molecular polymer, which is composed of various chemical components. As a viscous colloid separating serum and blood clots, it is physiologically inert. Because its structure contains a large number of hydrogen bonds, it has excellent thixotropic and separation properties. Usually, after the blood sample is collected into the test tube, it will be put into the centrifuge for operation when it is completely coagulated. Under the action of external force, the reticular structure will be destroyed, and it will gather together again due to thixotropy, so as to achieve the purpose of separation.   Barreled serum separation gel       2、 Method of adding serum gel       Generally, the separating gel is added to the test tube through the glue adding machine, and the standard amount of each tube is 0.8-1.2g. Note that the temperature of separating gel should not exceed 80 degrees. If it is difficult to add glue, water bath or other methods can be properly used for heating. The appropriate temperature is between 40-60 degrees, and the heating time should not be too long. After adding glue, put it into a 1500-2100 speed centrifuge for centrifugation for about 5 minutes. When sampling, use this tube containing separated gel to basically separate serum and blood cells, and effectively extract high-quality serum samples.       3、 Use of serum gel separation tube       The separation tube containing serum gel can be made of glass or plastic, and their operation is also different. Because the two have different clotting times for blood, the activation ability of plastic test tubes will be weaker, and the clotting time of blood will be longer than that of glass test tubes. Therefore, when using plastic separation tubes to collect blood samples, it is necessary to wait for about 4 hours until the blood is completely clotted before centrifugation on the machine. And during the placement process, it should be emphasized to separate the glass separation hose from the plastic separation hose to prevent confusion and centrifugation, leading to hemolysis.       As a supplier of blood vessel additives in China, Desheng has been researching and producing serum separation gel since 2005. After five generations of research and development, it continuously improves product performance, ensures customer experience, and gains market praise.

what comes first serum or gel       When checking their bodies in hospitals, many people go through the process of blood testing, mainly because the blood contains serum and plasma, which provide organic substances for the body. Once there is a disease, they first undergo changes, which is also the basis for effective judgment by medical staff. However, blood testing items are not always single and unchanging, and the requirements for different testing items vary. For example, for erythrocyte sedimentation rate testing, green heparin test tubes are required, while for routine serum testing, serum separation gel yellow tubes are required.       The yellow serum separation tube is the most widely used in clinical practice, as it can efficiently extract serum samples and obtain accurate detection reports in a short period of time. But in the actual operation process, sometimes it is found that the position of serum and glue is prone to change. What is this? Which one is on top?       1、 Performance of serum separation gel       Firstly, to accurately determine which separation gel is on top of the serum, it is necessary to fully understand the performance of the separation gel. As a hydrophobic organic compound, it is not only physiologically inert, but also has thixotropy and accurate specific gravity. When centrifugation is not carried out, it is generally located at the bottom of the test tube. But when the blood enters the tube and is completely coagulated, it is placed in a centrifuge. Due to its specific gravity ranging from 1.045 to 1.065g/cm3, while the serum has a specific gravity ranging from 1.026 to 1.031 g/cm3 and the blood clot has a specific gravity ranging from 1.090 to 1.095 g/cm3, the sequence presented after centrifugation and flipping should be that the serum is above the separation gel and the blood clot is at the bottom.         2、 The role of separation gel under serum       Due to the performance of the separation gel and the effect of external centrifugal force, it is located between the serum and the blood clot, which can effectively prevent the interaction behavior between blood cell components, ensure the stability of the serum sample, and also improve the efficiency of sample collection and the quality level of sample processing.       3、 The reason why the separation gel appears above the serum       Under normal circumstances, serum is always above the separation gel, but sometimes there may be cases where the serum flips below the separation gel. Why is this? In fact, this is related to its specific gravity. Accurate control of the specific gravity must be between the serum and blood cells. If it is too large or too small, it can lead to poor flipping or the situation where blood and separation gel are intertwined.       Based on the above introduction, I believe everyone already knows the location of serum and separation gel. The most important thing in the operation process is to ensure the reliable quality of the separation gel. As a professional manufacturer of serum separation gel, Desheng has been carefully researched and developed since its establishment, with precise formulation of key values, excellent flipping performance, and almost no poor separation effect.
