Double-wall Tubes

Golden Vac™ blue-top blood tubes are specially designed with double walls made of polypropylene (PP) and polyethylene terephthalate (PET). The PP inner tube is ideal for sensitive coagulation parameters due to its nonreactive characteristics, preventing the evaporation of liquid. The outer tube made of PET ensures a long shelf-life for the vacuum. Each tube contains sodium citrate at a concentration of 0.109 mol/L (3.2%) as an anticoagulant to prevent blood from clotting. The blood-to-additive ratio is 9:1, which is critical for valid prothrombin time results. After drawing blood, gently invert the tube 3-4 times to activate the anticoagulant. Centrifugation is recommended at 2000-2500 g for 10-15 minutes at 18-25° C.
