PYREX® Glass Centrifuge Tubes are ideal for a variety of lab applications, including oil distillation analysis, blood work, chemical determinations, and routine chemical separations. To minimize the likelihood of tube breakage, use proper adapters and/or rubber cushions in centrifuge tubes.
Choose from tubes with a beaded rim and tubes with a phenolic threaded screw cap featuring a glued-in, white rubber liner. EF4801M 15mL Tube has a 15-415 GPI thread finish, and EF4801N 50mL Tube has a 24-410 GPI thread finish.
Uniform borosilicate glass distribution in wall, taper, and bottom provides excellent mechanical strength.
Screw caps incorporate a temperature and steam resistant resin for long-lasting use.
White graduations offer good visibility and durability.
