Description
VACUETTE Coagulation Tubes are filled with a buffered 3.2% sodium citrate solution (0.109 mol/L) and are intended for venous blood collection for coagulation testing. Made from virtually unbreakable PET plastic, they provide a safer alternative to glass while maintaining reliable specimen integrity. The blue Safety Twist Cap with a vacuum release system supports hygienic handling and easy opening, and this tube is calibrated for a 3 mL draw volume.
