Cylinders are defined by four main characteristics:
Gas form - Compressed gas, refrigerated liquid (carbon dioxide, nitrous oxide), dissolved gases (acetylene), or cryogenic liquids.
Gas type - Oxygen, nitrogen, argon, acetylene, carbon dioxide, hydrogen, helium, rare gases, specialty gases, nitrous oxide, chemical gases and liquids, medical gases.
Gas purity - Up to 99.9999%.
Cylinder - Size (volume) and pressure, varying from country to country.
Cylinders are available as individual units or manifolded into 6-pack and 16-pack bundles for high-volume, unified dispensing.
We offer a full range of construction materials to match your operational requirements:
Standard & Specialty: Steel, aluminum, and high-strength light alloys
Composite Solutions: Advanced lightweight composite materials
Specialized Interiors: Porous mass interiors designed specifically for acetylene stability and safety

Department of Transportation (DOT) Compliance & Cylinder Testing:
Per DOT regulations, all compressed gas cylinders must be re-tested every 5 years. You can find the DOT number and the date of the last test stamped directly on the upper "shoulder" of the cylinder.
Standard Re-Test: Every 5 years
10-Year Extension: If a five-pointed star ($\star$) follows the date, the cylinder does not require testing for 10 years.

Non-refillable Steel Cylinders
A convenient and cost-efficient way to handle calibration gas mixtures... these smaller-sized, lightweight cylinders require no deposit or monthly rental charge. They are easier to handle, less expensive to ship, and use very little space. They also eliminate over-purchasing when only small quantities are necessary.
These steel cylinders are recommended for non-reactive gas mixtures and pure gases such as argon, helium and nitrogen. They combine a convenient, portable size with a wide range of capacities (from 17 liters (0.6 cu ft.) to 550 liters (19.4 cu ft.)) to handle any field calibration requirement.
