REAL GAZ supplies this product according to ISO 9809, ISO 6142 and ISO 17025, suitable for calibration, research and reference use.
Specialty cylinders can be supplied in steel or aluminium alloy, with valve outlets suited to flammable gases and optionally with internal passivation to preserve low-concentration propane mixtures. Smaller sizes are convenient for portable analysers and field calibration, while larger sizes serve fixed installations. Each cylinder is dedicated to a given gas to avoid cross-contamination during refilling.

Before connecting a specialty cylinder, inspect the valve outlet for dirt, check the seal and use a fresh gasket if required. Purge the regulator and line several times with the gas or an inert gas to remove air and moisture, then verify tightness at the working pressure. Record cylinder number, certificate reference and date of first use. When empty, close the valve, leave a small positive pressure and return the cylinder for refilling. Keep the certificate with your laboratory records so the mixture can be traced during audits and method reviews.
