Description of Coagulation Tube
01 Sodium citrate is used as anticoagulant to prevent blood from clotting.
02 Filled with a buffered sodium citrate solution in a concentration of 0.109mol/L (3.2%).
03 The blood to additive ratio is 9:1. The ratio of blood to anticoagulant is critical for valid prothrombin time results.
04 Immediately after draw, gently invert the tube 3-4 times in order to activate adequate anticoagulant.
05 Aluminum composite bags available to provide optimum protection against additive evaporation, UV light, dirt and mechanical influences.
06 All the necessary custom service options to fulfill your project requirements.
07 Centrifugation: 2000-2500g for 10-15 minutes at 18-25° C.

Advantages
Sodium citrate blood collection tube is also known as PT tube or coagulation tube. Citrate tube is used to collect venous blood for coagulation tests. Sodium citrate blood tube have a buffered sodium citrate solution of 0.109 mol/l (3.2%) or 0.129 mol/l (3.8%).
Usage: to research the hemostatic system.
Specimen: plasma.
Conditions of centrifugation: 2000 g for 10-15 minutes.
Immediately after taking the blood into the tube with citrate it must be carefully mixed at least 3-4 times to prevent micro clots.
