PYREX Gas Washing Bottle

Regular price $289.18

SKU: 31770-125EC

Gas Washing Humidifier Bubbler Bottle

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 diameter extra coarse fritted cylinder as the distributor.

With fused-on fritted cylinder 12 mm diameter on inlet tube and with Standard Taper 29/42 joint. With glass hooks on both bottle and cap, but without springs. Offered in 250 and 500 mL capacities, in coarse (C) and extra coarse (EC) porosities.

250EC and 250C bottles are 165 mm deep; 500EC and 500C bottles, 211 mm.
