BD Vacutainer 4ml Red Serum Blood Collection Tubes

BD Vacutainer 4ml Red Serum Blood Collection Tubes | Product Description

• In order to obtain serum samples from plastic tubes, the tube must have a coagulation activator added.
• As the plastic surface alone is insufficient to trigger the coagulation within an acceptable time, BD Vacutainer® plastic serum tubes have silica particles added for this purpose.
• These tubes are marked with the acronym CAT (Clot Activator Tube).
