PYREX® Gas Washing Bottle with Fritted Disc, Corning 31750 & 31760

These Corning PYREX® gas washing bottles provide an inexpensive but effective method for washing and drying gases. These bottles have large hexagonal bases for stability. Sidearm tubulations have an 8mm outer diameter. A 40/50 standard taper stopper is used to seal the top to the base. These bottles are a very effective way to humidify carbon dioxide-air mixtures for maintaining high humidity in gassed cell culture incubators. The gas enters the bottle through the top of the central vertical tube, the lower end of which is fritted and below the surface of the washing medium. After bubbling through the medium, the gas is removed via the sidearm of the bottle stopper. The standard taper stopper incorporates a tube with a 20mm diameter coarse fritted disc as the distributor. The fritted disc provides greater efficiency and more uniform dispersion of gas bubbles for complete absorption. Material: Borosilicate Glass Code 7740
