Constructed of clear, durable borosilicate glass, gas inlet tubes are useful for permitting gas to be introduced to the bottom of a reaction vessel or flask. They have very good chemical resistance, high temperature resistance, and minimal thermal expansion, giving gas inlet tubes a relatively high resistance to temperature changes. Gas inlet tubes are available in straight and bent models for convenient connection with tubing for bringing various gases.
