All non-refillable canisters are supplied in robust, lightweight aluminium alloy canisters. Once empty there is no need to return empty canisters, simply recycle via your normal waste stream. Canisters should be de-pressurised before recycling, the easiest way to do this is with our recycler tool which is also available to purchase on this site.

Non-refillable canisters like calibration gases manufactured by Air Products, are traceable to national standards and issued with a Certificate of Analysis in accordance with ISO 6141.

Shelf life is dependent on the gas type, for more information visit our specification page.

"Our business relies on simple bump testing of gas detectorson board marine vessels. Complex high pressure cylinders and regulators would make the job too difficult but we find the Air Products non-refillable offerings very easy to use and the equipment is simple to operate."

GMS Instruments, Rotterdam

"We are involved in the installation, commissioning and maintenance of a wide range of gas detection equipment into many market sectors. The fact that the Air Products’ range covers all of the flammable, toxic, quad-gas and corrosive gas requirements for this market is very important to us."

Autochim, France

"Personal, portable and fixed gas detection equipment is widely used in many safety critical applications and these items are often subjected to relatively harsh environments and working conditions. The gas sensing element within this equipment is perhaps the most fragile and crucial component, and if this was to fail, it would render the equipment useless. The selection of appropriate test gas is important to ensure the bump test is carried out correctly and as an active member of CoGDEM, Air Products know about it. They have contributed to the CoGDEM Guide to Gas Detection, a new hardback reference book which explains best practice and aids the selection of suitable test gases and equipment."
