A pressure gas regulator is an essential part of any laboratory; gas regulators are used to deliver gas at constant pressure and volume. A general-purpose gas pressure regulator can come in single-stage and two-stage models. High-purity gas regulators are designed for noncorrosive analytical, mildly corrosive research and process applications requiring precise, stable delivery pressure control. A specially-designed diaphragm allows flow control and maintains system purity. You can also find special-service gas regulators for gases that attack brass or copper, corrosive halogen gases, and electronic and semiconductor grade gases.
