Blood collection container tube

Green Vac-Tube ®tubes are PET evacuated tubes with color-coded (Table No. 1) closures. The tubes contain additives in different concentrations dependent on the amount of vacuum and the required additive-to-blood ratio for the tube. Additive choice depends on the analytical test method, and it is specified by the manufacturer of the test reagents and/or instrument on which the test is performed. Tube interiors are sterile.
