Specialty Medical Gases for Critical Research

From liquid nitrogen for cryopreservation to CO₂, oxygen, and custom gas mixtures, we supply the medical-grade gases that many of California's research institutions depend on.

PRIMARY FOCUS

Liquid Nitrogen (LN₂)

Our Primary Specialty

Liquid nitrogen is critical for cryopreservation and biobanking applications where failure means losing years of research and potentially life-saving discoveries. We understand that when you run out of liquid nitrogen, you risk losing priceless biological samples—stem cells, tissue samples, research specimens that cannot be replaced.
