What Our Customers Say

"Finding your company was a miracle. We had so many issues with our previous supplier; it was as if they didn't care. With Nitrex, we finally have peace of mind knowing our samples are protected."

"I went to a big competitor before I found Nitrogen Express. The competitor didn't show up as promised, and we thought our cells wouldn't survive over the weekend. We could never recover what was in those tanks. This was Friday night. Jason from Nitrogen Express showed up on Saturday at 8:30am. They're willing to go the extra mile."

"What a stark contrast it has been dealing with your company versus our last supplier. My only regret is that we didn't find you sooner. The reliability and responsiveness are exactly what we needed."

"I have never received the one-on-one support from anyone like I have from you and your company. You treat us like we're your only customer, even though I know you serve many facilities."

"Not having to stress about our liquid nitrogen supply has been very nice. The automatic monitoring and proactive refills mean we can focus entirely on our research."

"We are extremely happy with your service and would never consider using another vendor for liquid nitrogen. The 100% fill guarantee and on-site filling make such a difference."

"The emergency response guarantee isn't just marketing—they actually deliver on it. When we had an urgent need on a Sunday morning, they were there within 90 minutes. Incredible."

"Switching to Nitrex was the best decision we made this year. Our previous supplier's tanks were always only 80% full, and we were constantly worried about running out. Not anymore."

"When I was in trouble, I knew who to call and it was you guys. You always showed up. That's what matters in this business."

"We're done with welding suppliers. We needed a different solution for our clinical material, and Nitrex understood the difference between running a manufacturing facility and running a fertility clinic out of liquid nitrogen."

"Nitrogen Express will make your lab safer. They understand that this is clinical—we're storing patient material, and the liability is significant. They treat it that way."
