PYREX 31750-350C Gas Washing Bottle 350 mL with Side Inlet and Coarse Fritted Disc

The PYREX 31750-350C Gas Washing Bottle 350 mL with Side Inlet and Coarse Fritted Disc is a high-quality laboratory glass apparatus designed for efficient gas washing, gas absorption, and humidification during scientific and industrial laboratory procedures. Manufactured by Corning from durable borosilicate glass, this reusable gas washing bottle features a specially designed side inlet, a 24/40 standard taper glass stopper, and a large-diameter coarse fritted disc that provides uniform gas distribution through a suitable liquid medium. The coarse fritted disc, measuring approximately 60 mm in diameter, produces dispersed gas bubbles that promote efficient contact between the gas and washing solution. This design improves gas absorption and makes the bottle suitable for handling relatively large gas volumes. The bottle is particularly useful for humidifying carbon dioxide-air mixtures in cell culture incubators, helping maintain the high-humidity conditions required for laboratory cell cultivation. Its reinforced side inlet tube provides additional mechanical strength, while the transparent glass construction allows convenient observation of gas bubbling and liquid levels during operation. The PYREX 31750-350C is suitable for research laboratories, biotechnology facilities, pharmaceutical laboratories, chemical analysis laboratories, universities, and scientific institutions.
