Besides cylinders, another supply form are gas generators. The specialty gas generators that Linde offers produce hydrogen, nitrogen or zero air. Generators are frequently used as an easy and efficient supply source in laboratory environments with a constant gas demand.
For liquiefied air products such as Nitrogen, Argon or Oxygen and Carbon Dioxide supply containers would include portable cryogenic containers and dewars. Linde offers a special supply service for such liquefied substances, called CRYOSPEED®
Regulatory Requirements:
Gas cylinders are considered pressure vessels, and therefore governed by local authority rules and regulations. Some are non-returnable and others are recyclable.
