Specialty & Scientific Gases
Supagas supplies a wide range of specialty and scientific gases, including high-purity (HP) and ultra-high-purity (UHP) grades, certified mixtures, and customised blends. We can supply gases with up to 99.999% purity, meeting the strictest requirements for laboratories, research facilities, food packaging, aviation, and advanced manufacturing.
High Purity & Ultra High Purity Gases
High Purity (HP) and Ultra High Purity (UHP) gases are critical where even trace contaminants can affect results, equipment performance, or product quality. These gases are commonly used in laboratories, analytical testing, electronics manufacturing, and laser applications. Through the capabilities of the Nippon Sanso Australia group, including NATA-accredited laboratory services, specialty gases can be mixed, tested, and certified to controlled specifications. This ensures consistent composition and reliable performance, helping customers maintain accuracy, repeatability, and compliance.
Scientific, Laboratory & Analytical Applications
Our specialty gases are widely used in:
Gas chromatography and analytical instrumentation
Environmental testing and monitoring
Research laboratories and universities
Calibration and reference standards
Controlled experiments and testing environments
With a broad range of purities and specialty blends, we support both routine analysis and highly specialised scientific work.
Food Technology, Ripening & Modified Atmospheres
Specialty gases also play a critical role in food science and post-harvest applications. Products such as Ethylene, SupaRipe and MAP gas blends are designed to control ripening, extend shelf life and preserve quality.
Our MAP gases (SupaMAP 10–70) are tailored for different food types, packaging methods and storage conditions, supporting consistent results across food production and distribution.
Laser, Manufacturing & Advanced Industrial Uses
High-performance gases such as SupaLaser, HP/UHP Nitrogen, Oxygen, Argon and Carbon Dioxide are essential in precision manufacturing, laser cutting and advanced fabrication.
These applications demand:
Stable gas composition
Clean delivery
Consistent flow and purity
Our specialty gases are engineered to meet these requirements across demanding industrial environments.

Great service. We were stuck needing an LPG gas delivery. Our regular supplier was unable to provide the service. These guys arrived on the same day and assisted us after one phone call. They really went out of their way. Highly recommended!!!

Supagas made the supply of medical oxygen to my family home a seamless and personal experience. It is a confronting medical undertaking for the uninitiated. Naomi was particularly knowledgeable and guided me through the systems configuration to make the ordering easier than I could have imagined. I’ll use Supagas again and recommend Naomi.
