We're not just another gas supplier. We're a family-owned business that understands the critical importance of your research and the trust you place in us every single day.
Nitrex Specialty Gases was founded on a simple but powerful idea: medical and research customers deserve a gas supplier they can trust absolutely. Our owner started as a driver—he's been in the truck, made thousands of deliveries, filled countless cylinders, and knows firsthand what it's like at the customer location. That hands-on experience shapes everything we do.
This is a zero-defect business. When a fertility clinic stores embryos or a research lab preserves years of biological samples, there's no margin for error. We've built redundancies into every aspect of our operation so that the inevitable human mistakes don't result in lost material or compromised safety.
We understand the difference between running a welding shop out of nitrogen versus running a fertility clinic out of liquid. It's one thing to inconvenience a welder—it's another thing entirely when patient material is at stake. That's why we focus exclusively on critical-need customers who truly require reliability.
Our business is highly customer-centric and high-touch. The driver who shows up at your doorstep is the most important touchpoint in our business—he represents everything we stand for. We interview 100 candidates to hire one, because we know that when it matters most, it's about whether that person cares, shows up on time, and treats your facility with respect.

These aren't just words on a website. These are the principles we live by every single day.
We've designed our entire business around one goal: you should never have to worry about your gas supply. Multiple backup systems, proactive monitoring, and guaranteed emergency response.
As a family-owned business, every customer matters to us personally. You're not just an account number. We understand the critical importance of your work.
Medical-grade purity, proper certifications, and meticulous handling. We treat every delivery as if lives depend on it—because often, they do.
The driver at your doorstep is the most important touchpoint in our business. We interview 100 candidates to hire one. Our drivers have CDL licenses, TSA background checks, and monthly safety training. High retention means you see familiar faces who know your facility.
We've built our business by doing what other suppliers won't.
Most suppliers use the tank-swapping method: they fill tanks at their facility, transport them to you (losing 20% to evaporation), and swap them out. This means you're paying for gas you never receive, tanks get damaged in transit, and worse—your clean laboratory tank can end up in a dirty welding shop, then come right back to your sterile facility. You have zero control over where your tanks go or what environments they're exposed to.
We fill your tanks 100% full at your location. Your tanks never leave your facility—eliminating cross-contamination risks entirely. No evaporation loss. No transit damage. No contamination from other customers' environments. You get exactly what you pay for, every single time.
We don't wait for you to call us when you're running low. Our AutoFill monitoring system checks your tank levels every 10 minutes and automatically schedules refills before you need them.
You'll receive text notifications when we're on our way and when we're done. You can focus on your research, not your gas supply.
We're so confident in our reliability that we offer a $1,000 guarantee: if you're a customer and reach out between 8am-8pm any day of the week, and we don't respond within 2 hours, we pay you $1,000.
No other supplier will make that commitment. We do, because we know we'll keep it.
As a family business, we're personally invested in your success. We constantly check in with customers to ensure we're meeting your needs. When was the last time your current supplier sent you a survey?
