Nitrogen Express Information

Nitrex Specialty Gases is California's most reliable specialty gas supplier, serving biotech research labs, medical facilities, fertility clinics, and industrial customers throughout Southern California. We specialize in liquid nitrogen supply with a fundamentally different approach: we fill your tanks 100% full at your location — eliminating the 15–20% evaporation loss that comes with traditional tank swapping. You pay for what you get. Our proprietary Trust Gnosis™ weight-based monitoring system tracks your liquid nitrogen levels in real time, every 10 minutes, 24/7. We know when you're running low before you do — and we schedule your next delivery automatically. No more emergency calls. No more running out. Our commitment: if we don't respond to an emergency within 2 hours (8am–8pm daily), we pay you $1,000. That's how seriously we take reliability. We serve customers including UCSF, Stanford, UCLA, and leading biotech and medical facilities across California. 📞 (951) 356-4381 | 🌐 nitrexgas.com
