PYREX® 40 mL Heavy Duty Conical Centrifuge Tubes with White Graduations, Screw Cap

(This is the suggested replacement for 8124-40)

These heavy duty 40 mL PYREX® conical centrifuge tubes are made with increased wall thickness for greater mechanical strength. In order to conform to outside diameter and overall length limitations imposed by centrifuge rotors and supports, it has been necessary to reduce the capacity of these heavy duty tubes. The 40 mL tube is graduated with durable white enamel in 0.5 mL divisions to 10 mL, and from 10 to 40 mL in 1 mL divisions. The phenolic 24-400 GPI threaded screw cap is fabricated of a resin which is specially formulated to resist the effects of temperature and steam. For replacement caps, see No. 9999.
