Many laboratories across Australia are re-evaluating their gas supply methods. Relying on bottled gas can present ongoing challenges including delivery delays, rising rental and transport costs, and the hassle of managing cylinder changeovers and storage. These operational drawbacks are driving a growing number of labs to explore on-site nitrogen and oxygen generation as a more reliable, cost-effective and future-ready solution.

Why Labs Need Reliable Gas Supply

Nitrogen and oxygen play a critical role in laboratory environments. Whether it’s for purging and blanketing in chemical testing, inert atmospheres for materials analysis, sample preparation in food testing, or carrier gas in gas chromatography, a stable gas supply is essential for accuracy, repeatability and safety. On-site generators give laboratories consistent access to high-purity gas that supports core testing and research functions.

Limitations of Bottled Gas in Lab Settings

While bottled gas has been the standard for many years, it comes with built-in inefficiencies. Recurring delivery fees, fluctuating rental charges, and time-consuming logistics around inventory and storage can strain operational budgets. There are also safety considerations, with high-pressure cylinders requiring proper handling and compliance. Furthermore, inconsistent deliveries or sudden shortages can disrupt sensitive testing schedules.

How On-Site Gas Generation Works in a Laboratory

Modern gas generators for laboratories use either Pressure Swing Adsorption (PSA) or membrane technology to extract nitrogen or oxygen directly from ambient air. These compact systems are designed to operate quietly and efficiently within lab environments. Depending on your requirements, units can be wall-mounted or skid-mounted with integrated compressors and dryers. A properly sized system ensures a continuous flow of gas without the interruptions or guesswork associated with bottled supply.

Benefits of On-Site Nitrogen and Oxygen Generators

• Continuous supply: No more delivery delays or running out unexpectedly. Gas is generated on-site and on-demand. 

• Reduced operating costs: Lower ongoing costs compared to bottled gas logistics.

• Improved safety: Eliminates manual handling of cylinders and high-pressure risks.

• Space-saving: Frees up lab space previously used for cylinder storage.

• Environmentally friendlier: Cuts down on transport emissions and waste.

What to Consider Before Making the Switch

Before installing a laboratory gas generator, consider the following:

• Gas purity requirements: Match system specs to your application needs.

• Flow rate and usage: Understand your average and peak gas demands.

• Space and infrastructure: Ensure there is adequate space and ventilation.

• Servicing and maintenance: Schedule regular checks to maintain performance.

• Compliance for lab use: Confirm the system is suited for your industry.
