Helium gas

Best known as Balloon Gas for inflating balloons, helium is also available in a range of purities for other applications such as purging, welding and electronics manufacturing

Coregas can meet your needs for helium gas no matter where in  New Zealand you are based. Through our nationwide network of depots and 3rd party distributors, we supply high-quality, commercial helium gas to companies and individuals across the country. We manufacture industrial grade, laser grade and laboratory grade helium in Australia, in accordance with all applicable standards. For detailed information on purity levels, please see the certificate of conformance for the product in which you are interested.

Our industrial grade helium gas is widely used for inflating party balloons while helium 4.6 is used for shielding gas, resonator gas and laser cutting applications. Helium 5.0 is used for gas chromatography applications, in calibration gas mixtures, as a pressurising gas, in MRI equipment and various other critical applications. Helium 5.0 is also used in supercritical fluid chromatography, as helium head pressure carbon dioxide (HHPCD), and in liquid hydrocarbon calibration mixtures.

For further information on any of our helium gas products, please call or email us at your convenience.

Frequently Asked Questions

  • Where can I buy helium?

    Customers with an account can purchase direct delivery from Coregas, or through our national channel network. You can also purchase helium through our service center partners. Click here for our store locator.

    Coregas account customers can choose their preferred method to place an order. Coregas offers online ordering via our website, or our New Zealand based customer service team as well as through email.

  • How is helium stored?

    In common with other compressed gases, the cylinders in which helium gas is stored may explode if exposed to very high temperatures that cause the gas pressure to rise beyond the level of which the cylinders are designed to handle. Accordingly, helium gas cylinder tanks should be stored upright, in a well-ventilated storage area that is dry and cool. The storage area should be well ventilated, as helium leakages can cause asphyxiation.

  • How much is helium gas?

    The cost of compressed air from Coregas depends on the amount and grade that you order. If you would like an accurate quotation, please get in touch with us to let us know exactly what you need.

  • How long does a cylinder tank of helium last?

    How long it takes you to get through a helium cylinder tank will depend on the size of the tank, what you are using the helium for and how often you use it. You can either use our stock management service or ask us to help you calculate expected usage figures if you would like our assistance.

  • Is helium a flammable gas?

    Helium is an inert gas and is therefore not flammable. However, in common with other compressed gases, the cylinders in which it is stored may explode if exposed to very high temperatures that cause the gas pressure to rise beyond the level of which the cylinders are designed to handle.

  • Is helium poisonous?

    Helium gas is not poisonous but it can be dangerous to inhale because of the possibility of asphyxiation. By preventing the body from obtaining the oxygen it needs, helium can cause people to faint and be fatal in some cases.

  • What is the density of helium gas?

    The densities of gases are calculated by using their molecular weight and the number of molecules per litre at a given temperature and atmospheric pressure. At room temperature, helium gas has a density of 0.164 grams per litre, while air has a density of 1.18 grams per litre. In layman’s terms, it’s far lighter than air, which is what allows helium balloons to float.
