PYREX 31760-500C Gas Washing Bottle 500 mL with Coarse Fritted Disc

The PYREX 31760-500C Gas Washing Bottle 500 mL with Coarse Fritted Disc is a premium-quality, reusable laboratory glass apparatus designed for efficient gas washing, gas absorption, and humidification during scientific research and laboratory procedures. Manufactured by Corning from durable borosilicate glass, this tall-form gas washing bottle features a cylindrical body, stable hexagonal base, and removable standard taper glass stopper with an integrated gas distribution tube. The apparatus incorporates a 20 mm diameter coarse fritted glass disc with a nominal pore distribution of 40–60 micrometres. This disc disperses incoming gas into small bubbles, improving contact between the gas stream and washing liquid for efficient gas treatment. During operation, gas enters through the central vertical inlet tube, passes through the submerged fritted disc, bubbles through the washing solution, and exits through the sidearm outlet. The PYREX 31760-500C is particularly suitable for humidifying carbon dioxide-air mixtures used in cell culture incubators and for laboratory experiments requiring controlled gas-liquid contact. Its transparent construction allows easy observation of gas bubbling and liquid levels, making it suitable for chemical analysis laboratories, biotechnology facilities, pharmaceutical laboratories, universities, and research institutions.
