PYREX 31760-125EC Gas Washing Bottle 125 mL with Extra Coarse Fritted Disc

The PYREX 31760-125EC Gas Washing Bottle 125 mL with Extra Coarse Fritted Disc is a high-quality, reusable laboratory glass apparatus designed for gas washing, humidification, absorption and gas-liquid contact applications. Manufactured by Corning from durable PYREX borosilicate glass, this tall-form gas washing bottle features a stable hexagonal base, long neck, hollow glass stopper and an integrated gas-distribution tube fitted with an extra-coarse fritted glass disc. The 20 mm diameter extra-coarse fritted disc has a nominal pore distribution of 170–220 micrometres, allowing gas to disperse through a suitable washing liquid. Its relatively large pores offer lower resistance to gas flow than finer fritted discs, making it useful for laboratory applications requiring coarser gas bubbling. During operation, gas enters through the central vertical tube, passes through the fritted disc beneath the washing liquid and exits through the sidearm outlet after contacting the liquid medium. The bottle is particularly suitable for humidifying carbon dioxide-air mixtures used in cell culture incubators and for other controlled laboratory gas-treatment procedures. Its transparent construction allows convenient observation of gas bubbling and liquid levels, while its reusable design makes it suitable for routine laboratory applications.
