How to store unused blood coagulant solutions Additives for blood collection vessels

The use of high-efficiency coagulation promoting powder is very frequent in the daily work of medical laboratories. It helps with the rapid coagulation of blood samples, providing convenience for subsequent detection and analysis. To ensure the uniform distribution of coagulation promoting powder on the inner wall of the blood collection vessel, we usually need to prepare the coagulation promoting powder into a liquid of appropriate concentration. However, sometimes we may encounter situations where the accelerator solution is not used up, and it is particularly important to properly store the remaining accelerator solution to ensure that it can still maintain its effectiveness and stability in the next use.

Firstly, we need to clarify that a coagulant solution is a biochemical reagent, and its stability and effectiveness are influenced by various factors such as temperature, light, humidity, etc. Therefore, the primary principle for storing coagulant solutions is to avoid the influence of these adverse factors, and specific precautions are as follows:

coagulation promoting powder

1. Control temperature. The coagulant solution should generally be stored in a cool place, avoiding direct sunlight and high temperature environments. Specifically, the storage temperature should be controlled between 2-8 ℃, which is the appropriate storage temperature for most biochemical reagents. Excessive temperature can accelerate the decomposition and deterioration of the solution, while too low temperature may cause the solution to freeze, affecting its effectiveness.

2. Avoid lighting. Light is also an important factor affecting the stability of coagulant solutions. Intense light such as ultraviolet rays can damage the molecular structure of the solution, leading to its failure. Therefore, containers for storing coagulant solutions should be made of materials with good light shielding properties, such as brown glass bottles or black plastic bottles, and placed in areas with weak light, such as cool corners in the laboratory.

3. Pay attention to humidity. Excessive humidity may cause the blood coagulant solution to absorb moisture, affecting its concentration and stability. Therefore, containers for storing coagulant solutions need to have good sealing to prevent moisture from entering the air; Secondly, it is also important to note that the storage environment should be kept dry to avoid excessive humidity.

4. Clear labeling of labels. For the convenience of management and use, we need to clearly label the unused blood coagulant solution. The label should indicate the name, concentration, storage date, etc. of the solution. At the same time, it is necessary to indicate the storage location and usage precautions, so that others can easily understand them when using them.

5. Avoid pollution and cross contamination. Choose clean and disinfected containers to store unused blood coagulant solutions; When using the solution, a dedicated pipette or pipette should be used to avoid mixing with other reagents and prevent the growth or cross contamination of bacteria and other microorganisms.

6. Regular inspection and replacement. Unused coagulant solutions need to be regularly checked to ensure their quality and stability. If any color change, precipitation, or odor is found in the solution, it should be immediately stopped from use and replaced with a new solution. In addition, even if the appearance of the solution is normal, it should be replaced according to the expiration date to avoid using expired reagents.

Product packaging

Understanding the correct method for storing unused blood coagulant solutions is to avoid unnecessary waste while using them reasonably and efficiently. The high-efficiency coagulant powder produced by Hubei Xindesheng Material Technology Co., Ltd. has good quality and affordable prices. If you find it very troublesome to prepare your own coagulant, you can purchase coagulant suspension produced by Desheng (please note that the coagulant suspension here is not the same product as the solution prepared with coagulant powder mentioned above).
