What is the gel in a serum separator tube?

La description

It called serum separation gel.
Serum-separating tubes, also known as serum separator tubes or SSTs, are used in medical clinical chemistry tests requiring blood serum.
Serum separation gel is used to give the separation of blood clot and serum with stable and little affection on clinlcal test results.
 
Destription:
【Main ingredients】polymer compounds, white carbon black, etc.
【Properties】 Colorless transparent colloid, good thixotropy and air tightness, showing physiological inertness.
【Specific gravity】1.**5～1.**5g／㎝3
【Viscosity】8～*2×**4CP (centipoise)
 
The gel is composed of inert components, which are part of a polyester-based proprietary formulation. What is the purpose of the gel in BD Vacutainer SST and PST tubes? The gel forms a physical barrier between serum or plasma and blood cells during centrifugation.
And our New Desheng can customize usual gravity gel and high gravity gel with improved synthesis process which have good hot at mainland china market and more over the world.
Actually,our New Desheng owned two types of serum separation gel with passing ISO ***1 which are Polyacrylic acid separation gel synthesized from acrylic acid; separation glue synthesized from polyacrylic resin. And as about Degree of transparency, we could customized Transparent; translucent; opaque this three types.
