Corning Pyrex 12 ml Heavy Duty Conical Centrifuge Tube, Beaded Rim

These 12 mL heavy duty PYREX conical centrifuge tubes 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.
