VWR Gas Regulators

Gas cylinders provide the gas used to drive equipment for a number of laboratory applications. To regulate the delivery of the gas from the cylinder, the proper regulator selection is required. Whether your application requires high-purity, ultra-high purity, corrosive, or blended gas, the VWR Gas Regulator product line has a single-stage or multi-stage regulator to meet your needs.
