PFA Flasks with Screw Caps - 500 mL (500 mL)

Made from PFA copolymer to deliver outstanding chemical and solvent resistance over a temperature range of -260° to +270°C. Extremely low absorption and permeability levels associated with PFA make these flasks suitable for trace element analysis, isotope separations, sample digestions, and the handling of sensitive biological solutions. Flasks are translucent, so sample is easily visible. Graduation lines are highly legible, accurate, and permanent. Calibrated "To Contain" designated volume within Class A tolerances as specified in ASTM E 288, E 542, and E 694 standards. Supplied with PFA screw closures, which provide a secure seal from outside contamination. Autoclavable. Can also be sterilized using gas, dry heat, gamma irradiation, or chemical disinfectant.
