PYREX Bell Jars w/ Beaded Opening and Ground Flange

PYREX bell jars with the beaded opening are made from specially selected mold-blown blanks. The bottom flange has a finely ground finish to assure tight sealing with ground glass plates. The opening in the center of the top is flame-cut and beaded for greater strength and to increase the bearing surface when a No. 5½ rubber stopper is used. They are rated at 1-atmosphere of vacuum. -Warning: do not use with heat or pressure applications.
