Corning® 250 mL Class A Reusable Plastic Volumetric Flask, Perfluoroalkoxy-copolymer with GL-25 Screw Cap

Translucent flasks are supplied with a PFA screw cap. Screw caps provide hermetic seals and help reduce the possibility of outside contamination. The product is manufactured to Class A tolerances as defined by ISO 1042 and flasks have individually calibrated graduation lines. They withstand high temperatures and are resistant to a variety of aqueous solutions and organic solvents. These flasks may be autoclaved to 121ºC without affecting the graduation tolerance. Recommended routine cleaning up to 60ºC will preserve graduations. Height dimension is flask only, without screw cap.
