Corning® PYREX® Boiling Flasks with Round Bottoms and Short Necks

Flasks have full length outer 14/20 TS joints, but with shorter necks. They are manufactured from No. 7740 borosilicate glass. Wall thicknesses are carefully controlled to provide the proper balance between thermal expansion and mechanical strength for greater shock resistance. Their excellent chemical durability results in contamination-free results and long life under the toughest lab conditions. The normal working temperature for boiling flasks is 230°C.
