Bio Plus clot & gel activator tube is used for clinical biochemistry and immunology.
Inside the tube there is a barrier gel present at the bottom, which is a pure substance,
very stable in physical and chemical features. After centrifugation, the barrier can effectively
separate the serum from fibrin and cells, while preventing substance exchange between blood
cell and serum. As a result, it can keep biochemical characters and chemical components
of serum unchanged for a long time.
