Speciality Gas

Critical components for chemicals, biotechnology, materials processing, environmental, foods, semiconductors, and medical industries.

What Counts as a Specialty Gas

Specialty gas is defined as any gas — including pure gases like nitrogen, oxygen, and argon, or custom gas blends — that's tested for purity after the cylinder is filled.

Major gas manufacturers provide specialty pure gases in several grades. Each grade is tested for a defined set of impurities, such as levels of oxygen, moisture, total hydrocarbons, carbon monoxide, and nitrogen..

FAQs

Common questions about gas supply

Yes. We work to combine them on the same truck so receiving and billing stay simple, with one invoice when combined. This is our "One Truck" advantage.
If you're regularly receiving multiple cylinders per week, spending labor on cylinder changeouts, or running into stockouts, it's worth a conversation. Bulk and micro-bulk reduce handling, lower per-unit cost at volume, and free up floor space.
High purity is typically 99.998%, ultra-high purity is 99.999%, and research grade is 99.9999%. The higher the grade, the tighter the spec on impurities like oxygen, moisture, hydrocarbons, and CO. The right grade depends on your application — we'll help you specify.
Yes. We distribute medical air, oxygen, nitrogen, nitrous oxide, helium, and CO₂ to clinics, dentists, vets, EMS, and labs, plus food-grade gases for beverage and food processing applications.
Yes. You can purchase, fill, or exchange cylinders at select branches, and we offer rental on storage vessels and related equipment. Ask us about safe storage and transport — we stock carts, racks, and stands designed for cylinders.
Our real-time telemetry tracks bulk tank levels and sends alerts at preset thresholds, so we usually get ahead of low levels before you notice. If you do need emergency supply, special and 24/7/365 emergency deliveries are available across our service area.
