Application

Oxygen is a colourless, odourless, oxidizing gas that is slightly heavier than air. Examples of applications include special analytical processes (e.g. total organic carbon [TOC] ) and use in the automotive industries. Gas is easy to handle in a small, light pressure can, while the disposable container allows for aluminium recycling when finished.
