Gas Washing Bottles

These Corning Pyrex gas washing bottles provide an inexpensive but effective method for washing and drying gases. A 29/42 Standard Taper stopper is used to seal the top to the base. Using this bottle is 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 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 plain tip tube as the distributor. The bottle has a large hexagonal base for stability. Sidearm tubulations are 8mm O.D.. Material: Borosilicate Glass Code 7740.

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 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 coarse or extra-coarse fritted cylinder as the distributor.

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

Kimble KIMAX® gas washing bottle for washing or drying gases. Gas enters the bottle through the center tube and exits into the bottom of the bottle. On rising through the washing or drying medium it is thereby washed or dried and passes out of the bottle through the side tube of the bottle stopper. Both inlet and outlet tubes accept 1/4 inch I.D. flexible tubing. The 125mL size is sometimes referred to as a "Dreschel" type.

These gas washing bottles have a fritted cylinder and a standard taper stopper. This tall form unit is supplied complete with hooks and two springs. A polyacetal clamp will work in place of the springs.
