The reference number 362788 contains 9 mg of dried K2EDTA, and reference number 362799 contains 15.8 mg of K2EDTA yielding a concentration of 1.8 mg EDTA/mL of blood when the evacuated tube is filled correctly to its stated draw volume. The tube also contains a polyester gel that upon correct centrifugation (1,100xg for 10 minutes, swing-out bucket rotor) forms a barrier between the plasma and most of the cellular elements, allowing for transportation of the BD PPT™ Tube without removal of the plasma. Only the inside of the tube is sterile. The tube is not pyrogen free.
