| Message: | 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.
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.
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. |
