What is the cost of lab N2 gas in Australia?

ROI for lab supplying multiple LC-MS instruments, fume hoods & for sample prep

Typical usage: 240LPM (14.4 m3/hr), 98% purity, 12hrs per day, 5 days per week (Cylinders)

A nitrogen cylinder delivery contract may seem like the easiest way to manage your laboratory budget, however, the purchase of a nitrogen gas generator is a more cost-effective and environmentally friendly way to secure ongoing nitrogen gas supply. While the initial outlay for cylinders is low, contracts are often subject to regular price increases, as well as hidden costs such as regulator maintenance, delivery, fuel and cylinder & pallet rental charges, which can soon add up.

 

Typical costs associated with ordering cylinders

A gas generator offers a more economical solution, typically offering savings versus cylinder supply, within the first year of ownership whilst removing repeated cylinder deliveries, reducing your lab’s carbon footprint.


The table below is a break down of the costs associated with ordering 19858 cylinders:

Typical costs associated with ordering 87147 litres of liquid N2

ROI for 240LPM (14.4 m3/hr), 98% purity, 12hrs per day, 5 days per week (Liquid N2/Dewar/Bullet)

For labs using liquid nitrogen to supply their laboratory, there are significant cost savings available when using a nitrogen generator instead. Beyond the cost savings, on-site gas generation greatly decreases asphyxiation issues associated with the expansion of Liquid N2 to gas and dangers of cold burn associated with handling cryo liquids. With fewer deliveries your lab will benefit from a reduced carbon footprint (Consider the environmental impact of of purifying, cryocooling, transporting and evaporating Liquid N2) and with gas on-demand, no more waiting for deliveries to arrive, not to mention the space savings a gas generator can provide when compared with on-site liquid N2 storage.
