PYREX 31760-500S Gas Washing Stopper with Coarse Fritted Disc

The PYREX 31760-500S Gas Washing Stopper with Coarse Fritted Disc is a high-quality replacement glass stopper assembly designed for the PYREX 500 mL gas washing bottle, model 31760-500C. Manufactured by Corning, this reusable laboratory accessory incorporates a standard taper glass stopper, an integrated gas inlet tube, and a coarse fritted glass disc for distributing gas through suitable washing liquids. The 20 mm diameter coarse fritted disc has a nominal pore distribution of 40–60 micrometres. It disperses incoming gas into smaller bubbles, improving gas-liquid contact during laboratory gas washing, absorption, and humidification procedures. The stopper features a 40/50 standard taper connection and approximately 8 mm outside diameter tubing for compatibility with the corresponding PYREX gas washing assembly. Ideal for chemical laboratories, biotechnology facilities, pharmaceutical research institutions, and universities, this replacement component allows laboratories to maintain compatible gas washing equipment without purchasing an entirely new bottle. Important: This product includes the stopper and coarse fritted disc assembly only. The 500 mL gas washing bottle is sold separately.
