High-quality manufacturer of serum separation gel choose Desheng

Serum separation gel is mainly composed of silicone rubber, macromolecular hydrocarbons, hydrophobic glue, etc. As a high molecular polymer, it is insoluble in water and inert. It is a thixotropic viscous liquid with a density of 1.04-1.05 mmol /L, it has the advantages of oxidation resistance, high temperature resistance, low temperature resistance, and good air tightness.

The reason why the serum separation gel can separate serum and blood cells is because the serum density is 1.026-1.031 mmol/L, and the blood cell density is 1.090-1.095. Due to specific gravity, the separation gel is just between the serum and blood cells, so under normal circumstances After the blood is centrifuged, there will be three layers of serum, separating gel, and blood cells in sequence. 

There are generally two types of separation gel blood collection tubes commonly used in laboratories: serum separation gel coagulation tube and plasma separation gel anticoagulation tube. The serum separating gel coagulation tube is to add a coagulant to the blood collection tube to shorten the blood coagulation time, get the serum quickly, and report the result in the shortest time. The glass blood collection tube does not need to add a coagulant, and blood contact with the glass tube wall will trigger blood coagulation. When the blood coagulation factors Ⅺ and Ⅻ come into contact with plastic blood collection tubes, their ability to be activated is very weak, and a coagulant must be added to shorten the clotting time. The plasma separator gel anticoagulant tube is sprayed with anticoagulant such as lithium heparin on the inner wall of the separator gel blood collection tube to meet the needs of rapid plasma biochemical emergency testing.

At present, serum separation gel blood collection tubes have been widely used in clinical laboratories. The separation gel can form an isolation layer between cell components and serum (plasma), effectively prevent the exchange of substances between blood cells and serum (plasma), and guarantee serum within a certain period of time The stability of (plasma) components. In the clinical application of separation gel blood collection tubes, many irregular operations will affect the separation effect, and some separation gel blood collection tubes interfere with some test items. These problems are not easy to be found in daily quality control and routine testing. In order to ensure the authenticity and credibility of the test results, it is very important to do a good job of quality control of blood samples before testing.

Desheng is a high-quality manufacturer specializing in the production of serum separation gels. In addition to working hard to improve the quality, it is also committed to providing laboratory personnel with a set of clinical blood sample solutions, that is, operations during blood collection tube transportation, storage, blood collection, and centrifugation. Standards, etc., truly achieve first-class quality and service.
