Conical 15 ml and 50 ml centrifuge tubes are made of premium polypropylene for clarity and centrifugal strength. They are supplied sterile, and although they are autoclavable, their polyethylene screw caps are not. Tubes and caps may be frozen at temperatures as low as -45°C. The maximum centrifugal force is 12,000 xg for the 15 ml tubes and 15,000 xg for the 50 ml tubes*. Caps have a flat top surface for easy marking.
The Free Standing tubes have a “skirted” bottom that allows the tube to stand upright without a separate test tube rack.
