Medical Disposable Vacuum Blood Collection Tube of Gel and Clot Activator Tube (SST Tube)

Gel and Clot Activator Tube is used for clinical biochemistry and immunology and drug testing. The coagulant is evenly sprayed on the inner surface of the tube, which greatly shortens the clotting time. After centrifugation, the gel will solidify and completely isolate the serum from the fibrin cells, acting like a barrier, effectively preventing the exchange of substances between the serum and the cells. Improve the efficiency of serum collection, obtain high-quality serum, and obtain more realistic test results. Keep the serum stable for more than 48 hours, without significant changes in biochemical properties and chemical components, and can be directly used in sampling analyzers.

These tubes should be used with care when measuring drug or hormone levels because the drug or hormone may diffuse from the serum into the gel, causing a reduction in measured level. The gel in SST II tubes (which appears slightly less opaque) is supposed to have less effect on drug levels in serum.
