PYREX 31770-125C Gas Washing Bottle 125 mL with Coarse Fritted Cylinder

The PYREX 31770-125C Gas Washing Bottle 125 mL with Coarse Fritted Cylinder is a high-quality, reusable laboratory glass apparatus designed for efficient gas washing, gas absorption and gas humidification during scientific research and chemical laboratory procedures. Manufactured by Corning from durable borosilicate glass, this tall-form gas washing bottle features a cylindrical body, a stable hexagonal base and a removable standard taper glass stopper incorporating an integrated gas distribution tube. The apparatus features a 12 mm diameter coarse fritted glass cylinder with a nominal pore distribution of 40–60 micrometres. This fritted cylinder disperses incoming gas into small bubbles through the washing liquid, improving gas-liquid contact for effective gas washing and humidification. During operation, gas enters through the central vertical inlet tube, passes through the submerged fritted cylinder and bubbles through the washing solution before exiting through the sidearm outlet. The PYREX 31770-125C is particularly suitable for humidifying carbon dioxide-air mixtures in cell culture incubators, helping maintain the high-humidity conditions required for laboratory cell cultivation. Its transparent construction allows convenient observation of gas bubbling and liquid levels, making it suitable for chemical analysis laboratories, biotechnology facilities, pharmaceutical laboratories, universities and scientific research institutions.
