These 250 mL 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 are 8mm O.D. A 29/42 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 12mm diameter coarse fritted cylinder as the distributor. This coarse frit has a nominal pore distribution of 40 to 60 µm. Please check the Guide to Selecting and Using Fritted Glassware in our Technical Information Listing for additional information on fritted ware.
