Coagulation tubes are filled with a buffered sodium citrate solution. They are available with a citrate concentration of 0.109 mol/l (3.2%) or 0.129 mol/l (3.8%).
Coagulation tubes are mainly used for examination of coagulation parameters and can provide an excellent condition for the test of PT, APTT VALUES.
Coagulation Tube with Sandwich Material consists of inner tube made of PP and outer tube made of PET. Inner tube made of PP can avoid the additive decrease, which maintains the concentration of sodium citrate stable. Outer tube made of PET can guarantee vacuum stable for long time.
Additive: 3.2% Sodium Citrate
