These 5 ml Gel & Clot Activator Vacuum Tubes are supplied by Chargen Life Sciences. They contain an inert acrylic gel which acts as a barrier during separation. These 5 ml Gel & Clot Activator Vacuum Tubes are routinely used in chemical test, immunoassays and in electrochemical analysis. The tubes measure 13 x 75 mm and can draw 5 ml of blood. The additives present are a gel with blood clot activator (BCA) along with a silicon interior. The clotting time for these tubes is less than 30 minutes. The recommended centrifugation speed is between 3500 to 4000 rpm for 5 minutes. Post centrifugation, the gel solidifies.

The gel which acts like a barrier is present at the bottom of the vacuum tube. Post centrifugation the gel barrier separates the serum from the fibrin and cells as well as prevents substance exchange between blood cells and serum. Because of this vacuum tube is able to keep the biochemical characteristic and chemical components of serum stable over a period of time. The 5 ml Gel & Clot Activator Vacuum tubes have a gold coloured cap. Theyre made from high quality PET material. Theyre cost efficient, durable, sterile and disposable. They have a shelf life of 24 months.
