Gas Syringes
Gas syringes provide accurate measurement and collection of gases during laboratory experiments.Constructed from durable glass or plastic with smooth plunger action, they ensure precise volume control.Australian laboratories use gas syringes for reliable gas analysis and demonstration purposes.

Gas Syringe, 100 mL BORO 3.3 Glass is designed for collecting, transferring and observing gas volumes during compatible laboratory experiments. The clear graduated barrel allows users to follow the movement of the plunger and read the volume of gas held inside, making the syringe useful for chemistry demonstrations, gas-law investigations and reaction experiments where gases are produced or consumed.
During use, gas enters the barrel through the syringe connection and moves the plunger as the internal volume changes. It may be connected to compatible reaction vessels, delivery tubing or laboratory apparatus, depending on the experimental setup. Connections should be secure and leak-resistant so that gas is not lost while the reading is being taken.
The 100 mL barrel is made from BORO 3.3 borosilicate glass. This glass type has low thermal expansion and recognised resistance to water, acids and many chemical substances under suitable laboratory conditions. Its transparency also helps users check the barrel, graduations and plunger position throughout an experiment. ISO 3585 specifies the properties of borosilicate glass 3.3, while ISO 4803 covers borosilicate glass tubing used in laboratory glassware manufacture.
Gas volume varies with temperature and pressure, so experimental conditions should remain stable when results are compared. Compressing the plunger reduces the enclosed volume and raises the gas pressure, while temperature changes may also alter the observed volume. These factors are particularly relevant during Boyle’s law, pressure-volume and gas-production experiments.
Before each use, the glass barrel should be inspected for cracks, chips or other visible damage. The plunger should move smoothly and should never be forced. Users should also confirm that the gas, tubing, connector and experimental pressure are suitable for the syringe. Flammable, toxic, corrosive or reactive gases require suitable ventilation, personal protective equipment and an approved laboratory procedure.
ASTM E438 covers glass types commonly used to manufacture laboratory apparatus, including low-expansion borosilicate glass. ISO 3585, ISO 4803 and ASTM E438 are useful material references, but they should not be stated as confirmed product compliance claims unless supporting manufacturer documentation is available.
For LabChoice Australia customers, the Gas Syringe, 100 mL BORO 3.3 Glass is a practical choice for schools, universities, chemistry laboratories, physics teaching facilities and research environments carrying out compatible gas collection, gas-volume measurement and pressure-volume demonstrations.
