Corning Pyrex Vista™ 250 ml Short Neck Boiling Flask, Round Bottom, 24/40 Standard Taper Joint

These 250 mL PYREX VISTA™ round bottom boiling flasks have full length outer 24/40 Standard Taper joints, but with shorter necks. Wall thicknesses are controlled to provide balance between thermal expansion and mechanical strength for greater shock resistance. The 250 mL round bottom boiling flask is designed to ASTM E-1403. Adapter Nos. 8800, 8820 and 8825 are used to connect flasks with different size joints, thus allowing numerous combinations for diverse assemblies.
