PYREX 31760-250C Gas Washing Bottle 250 mL with Coarse Fritted Disc

The PYREX 31760-250C Gas Washing Bottle 250 mL with Coarse Fritted Disc is a high-quality, reusable laboratory apparatus designed for washing, humidifying, and treating gas streams during scientific and chemical laboratory procedures. Manufactured by Corning from durable PYREX laboratory glass, this tall-form gas washing bottle features a stable hexagonal base, a long cylindrical body, and a removable standard taper glass stopper with an integrated gas distribution tube. The bottle 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, increasing contact between the gas stream and the washing liquid for effective gas absorption and humidification. During operation, gas enters through the vertical inlet tube, passes through the submerged fritted disc, and bubbles through the washing medium before exiting through the sidearm outlet. The bottle is particularly useful for humidifying carbon dioxide-air mixtures in cell culture incubators, helping maintain suitable humidity conditions during laboratory cultivation. Its transparent glass construction allows laboratory personnel to observe gas bubbling and liquid levels, while its reusable design makes it a practical choice for chemical, pharmaceutical, biotechnology, and research laboratories.
