A gas syringe is a piece of laboratory glassware used to insert or withdraw a volume of a gas from a closed system, or to collect and measure the volume of gas evolved from a chemical reaction.
Contents
General
A gas syringe has an inner syringe chamber with a ground glass surface, while the syringe barrel also has a ground glass surface. The ground surface of the barrel moves freely within the ground glass surface of the syringe chamber with very little friction. The close mating of these ground glass surfaces also gives a reasonably gas-tight seal. Some gas syringe models have a glass or PTFE stopcock.
