Industrial Cryogenic Liquids
Ultra High Purity Gases are single gases; such as Oxygen, Hydrogen, Nitrogen, Argon, Helium, Oxygen, Carbon Dioxide and in
other Speciality Gases, with a purity of equal or greater than 99.9995% meaning that 0.0005% of the gas is comprised of other
gases (impurities).
Ultra high purity gases usually cost more than gases of lower purities due to the process involved in making the gases.
One such method of purification uses filters of decreasing pore size to remove larger particles as the gas enters, and smaller
particles as the gas continues through, such that enough impurities are removed from the gas to achieve Ultra High Purity.
Speciality Gases provides certified ultra pure gases i.e. Nitrogen, Argon, Helium, Zero Air, Hydrogen to be used as carrier
gas in Gas Chromatographs (GCs) and other analytical instruments.
Our ultra pure gases have stringent high-purity specifications. We achieve consistent high-purity through extensive gas
cylinder preparation, dedication of gas cylinders for gas service and quality control at every step.
By using our High purity Gases you will optimize cost and quality of analytical results, regardless of application and
significantly extend the life of GC columns, detectors and instruments.

PACKAGING
Cryogenic liquids are shipped and used in thermally insulated containers. These cryogenic liquid containers are specifically
designed to withstand rapid temperature changes and extreme differences in temperature.
Liquid Dewar Flasks
Liquid Dewar flasks are non-pressurized, vacuum-jacketed vessels, somewhat like a “thermos bottle”. They should have a loose
fitting cap or plug that prevents air and moisture from entering, yet allows excess pressure to vent. Flasks containing Helium,
Hydrogen and other low-boiling liquids have an outer vessel of liquid Nitrogen for insulation.
Laboratory Liquid Dewar Flasks
Laboratory liquid dewars have wide-mouthed openings and do not have lids or covers. These small containers are primarily
used in laboratories for temporary storage.
Liquid Cylinders
Liquid cylinders are pressurized containers specifically designed for cryogenic liquids. This type of container has valves
for filling and dispensing the cryogenic liquid, and a pressure-control valve with a frangible (bursting) disk as backup
protection. There are three major types of liquid cylinders, which are designed for dispensing:
- Liquid or gas
- Only gas
- Only liquid
