Emerald Flat Screw Cap PP 15mL & 50mL Centrifuge Tubes- 500 per case
Conical 15ml and 50ml 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 for both 15ml and 50ml tubes is 9000xg. Caps have a flat top surface for easy marking and labeling. The "Free standing" model features a ‘skirted’ bottom that allows the tube to stand upright without a separate test tube rack.
