PYREX® 350mL Gas Washing Bottle w/ Side Inlet and Coarse Fritted Disc

These 350mL PYREX® gas washing bottles provide an inexpensive but effective method for washing and drying gases. Sidearm tubulations are 10mm O.D. The side inlet tube on this bottle has a rod sealed to the bottle near the top for extra strength. A 24/40 Standard Taper stopper is used to seal the outlet tube 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 outside vertical tube which connects to a 60mm diameter coarse fritted disc at the bottom of the bottle below the surface of the washing medium. After bubbling through the medium, the gas is removed via the sidearm of the bottle stopper. The large diameter fritted disc permits the handling of large volumes of gas and provides greater efficiency and more uniform dispersion of gas bubbles for complete absorption. This coarse frit has a nominal pore distribution of 40 to 60µm.
