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

The PYREX 31770-125EC Gas Washing Bottle 125 mL with Extra Coarse Fritted Cylinder is a premium-quality, reusable laboratory glass apparatus designed for washing, humidifying and treating gas streams during scientific and chemical laboratory procedures. Manufactured by Corning from durable PYREX borosilicate glass, this tall-form gas washing bottle features a cylindrical body, a stable hexagonal base and a removable hollow glass stopper incorporating an integrated gas distribution tube. The apparatus is equipped with a 12 mm diameter extra-coarse fritted glass cylinder with a nominal pore distribution of 170–220 micrometres. The fritted cylinder disperses incoming gas through the washing solution, promoting gas-liquid contact while offering lower resistance to gas flow than finer fritted distributors. The bottle is especially useful for humidifying carbon dioxide-air mixtures used in cell culture incubators. Its transparent glass construction allows laboratory personnel to observe gas bubbling and liquid levels during operation. Suitable for chemical analysis laboratories, biotechnology facilities, pharmaceutical laboratories, universities and scientific research institutions.
