Gel Clot Activator tube ,Blood collection tubes

 Used for clinical biochemistry and immunology .The tube inner walls are specially processed for preventing the sticking and hemolysis. Inside the tube there is a barrier gel present at bottom,which is a pure substance,very stable in physical and chemical features. The barrier gel with high temperature-resisting property will not change inside at all. 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.Serum can also be aspirated directly from the collection tube,no need for transfer to another container.
