What is the performance index of serum separating gel?
With the rapid development of medical automation, the reagent that will be frequently used in immunology, hematology and clinical testing is serum gel, which can effectively separate serum, obtain samples, improve testing efficiency and ensure the accuracy of results. There are many manufacturers producing serum separating gel in the market, with different raw materials and performance index requirements for each manufacturer, and the quality of the final product has its own advantages and disadvantages. What are the performance indicators of serum separating gel? What are the specific requirements?
1、 Specific gravity
The specific gravity of serum separating gel should be located between serum and blood cells to isolate and form a barrier. Generally, the specific gravity of whole blood is 1.050-1.060, the specific gravity of red blood cells is 1.080-1.090, and the specific gravity of plasma is 1.025-1.030. The specific gravity of serum separating gel is required to be 1.045-1.065, just between serum and blood cells, which can effectively extract high-quality serum samples.
2、 Viscosity
The viscosity value of serum separating gel is between 100000 and 200000 li poise. The performance index requirements based on this have a certain impact on the gel adding process and fluidity, and are also important indicators to measure the quality of serum separating gel.
3、 Physiological inertia
The serum separating gel is required to be physiologically inert and made of hydrophobic material. It will not react during the process of direct contact with blood in the test tube, and will not affect the blood composition, so as to avoid inaccurate results and the occurrence of wrong judgment by medical personnel.
4、 Irradiation resistance
The vacuum blood collection tube is sterile for blood testing, which usually requires sterilization. It is required that the performance of the serum separating gel will not change after irradiation sterilization, and it is not easy to age, which will affect the experimental process.
5、 Stability
The stability requirements are mainly in two aspects. One is that the separation gel can ensure that it will not deteriorate within the validity period and has stable performance in the process of placement or transportation. The other is that the serum separation gel test tube, when added with other reagents at the same time, has compatibility and will not affect the detection due to the effect of other reagents.
Desheng is the first one among many enterprises to research and develop serum separating gel. After four generations of research and development, its performance is stable. Its key indicators can also be customized according to your requirements. The product quality is widely recognized by customers. A large number of products are sold in stock, which can fully meet your needs. Welcome interested parties to click the website for details!
