ESR Vacuum Blood Collection Tube

ESR tubes contain a 3.8% buffered tri-sodium citrate solution (0.129mol/l) with the mixing ratio of 1 part citrate solution to 4 parts blood. They are used for blood collection and anticoagulation for sedimentation rate test.

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.
