You Searched For: VWR International

Gas regulators are useful for gas chromatography applications where a constant working pressure is important over a wide range of inlet pressures, outlet pressures and flow rates. The easy-to-read gauges have large diaphragms to ensure a constant pressure delivery even when there is a change in cylinders or tanks. Regulators have a brass body and are suitable when small changes in the gas delivery pressure will not degrade performance.
