PYREX® 40 mL Heavy Duty Conical Centrifuge Tube with White Graduations, Beaded Rim

These 40 mL heavy duty PYREX® conical centrifuge tubes have durable white enamel graduations and are made to the same O.D. and length specifications as No. 8060, but 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 these heavy duty tubes. The 40 mL size is graduated upward from tip in 0.5 mL divisions to 10 mL and from 10 to 40 mL in 1 mL divisions.
