These PYREX® EZ Access™ volumetric flasks have an extra heavy duty glass wall significantly increases the product durability. These flasks are calibrated "to contain" (TC) and designed to meet Class A, ASTM tolerances for volumetric flasks. The wide funnel-like threaded top plus the wide neck design allows for easy filling and mixing of various materials into solution. This extra wide neck also allows access to larger capacity pipets.

Corning 5650 PYREX® Class A Volumetric Flask with Screw Cap

These PYREX® standard volumetric flasks conform to Class A capacity tolerances prescribed by ASTM. However, to facilitate transfer of crystals, salts and powders, the open end has been expanded on the 25mL and 50mL sizes. The standard 18-410 G.P.I. thread screw caps have a durable cone-shaped polyethylene liner. The Poly-seal cap insures a leak-resistant closure and no contamination when working with most common reagents.
