Cylinder Gas Regulator for laboratory — clean, precise delivery for analytical work
A Cylinder Gas Regulator for laboratory work must deliver gas at a stable low pressure without adding contamination.
REAL GAZ supplies regulators for helium, nitrogen, hydrogen, argon and calibration mixtures used in analytical instruments.

Two-stage designs hold outlet pressure constant as the cylinder empties, which keeps baselines steady on gas chromatographs. Diaphragm seals and stainless steel or chrome-plated brass bodies limit permeation and outgassing. Outlet ranges such as 0–4 bar or 0–10 bar match the typical inlet needs of benchtop instruments.
Gas is analysed to ISO 6142 and ISO 6143 for mixtures and prepared under ISO 17025-aligned practice, for analytical and research laboratories.
Good laboratory practice around cylinders reduces both cost and risk. Mount cylinders on a wall bracket or stand, label them with gas name and expiry date where applicable, and use dedicated regulators for each gas so that residues do not mix. Purge the connection with the gas before opening the instrument line, and leak-check with a suitable detector rather than soap solution when working with hydrogen or helium. Typical cylinder sizes of 10 to 50 litres at 200 bar suit most benchtop instruments, while smaller lecture bottles serve occasional use. Regulators should be serviced on a defined schedule and replaced if the outlet drifts.
🏭 Where Laboratory Regulators Are Used
