The physical properties of the most frequently used gases are also compiled in our mobile “Gasprops”- App, Messer Schweiz AG Seonerstrasse 75 5600 Lenzburg which is available for iOS and Android. info@messer.ch Version 1.1 (05/2020) http://www.messer.ch/ Gases for Life | High Purity Gases Cylinder connection and equipment The valve outlet connections of gas cylinders comply with the relevant national standards. These standards define the valve outlet connections depending on the type of gas. Only the outlet connections of 300 bar cylinders are defined EU-wide in the ISO 5145:2004. The appropriate connection is specified on the product data sheet. Further information Special brochures are also available on the following topics: • Specialty Gases • Gas Mixtures • Helium • Balloon Helium • CANgas • Specialty Gas Equipment • Process Gases for Analytical Applications • Environmental Analysis • myLab.

A cylinder pressure regulator can be used if only one application has to be supplied with gas and the cylinder can be placed right next to the point of use. With a central gas supply system, consisting of pressure control panels, pipelines and tapping points at the various points of use, the gas cylinders are safely stored outside of workplaces. Service and support We will be glad to support you in choosing the suitable gas quality and gas supply equipment for your specific requirements.
