High quality gases play critical roles in process manufacturing and research and development   for the Life Science, --- Analytical Laboratory and other high technology industries.  The right gases delivered through the right distribution systems  ensure system consistency, product uniformity and quality compliance.


As the best source for cryogenic gases in California, WestAir provides you with materials and support for the systems you use in a variety of applications:




  • Cryogenic freezing of bone marrow, stem cells, pharmaceutical cell lines and other critical samples.
  • Cryogenic condensation for volatile organic compound (VOC) systems needed to comply
    with hazardous air pollutant regulations.
  • Non-freezing direct and indirect cooling for rapid cooling and precise temperature control   needed in reaction and process optimization.
  • Inducing simultaneous nucleation of all the vials inside the freeze dryer chamber. 
  • Freeze-drying (lyophilization of) sensitive, high-value, sterile products such as biologic
    formulations, vaccines and non-aqueous solvent-based drugs.
  • Overcoming dissolved-oxygen limitations in aerobic microbial fermentation systems.
  • Primary and back-up refrigeration equipment.
  • Secondary and tertiary cryogenic back-up systems.

Nitrogen plays important roles in maintaining process quality. You may need gaseous nitrogen for blanketing: protecting processes from moisture intrusion, oxidation, degradation and contamination. Additional uses include purging, pressure transferring, mixing and capturing air emissions. You also need cryogenic liquid nitrogen to control temperature in reactor cooling applications and to preserve biological samples.


Oxygen plays critical roles in cell growth applications in fermenters and bioreactors.

Carbon Dioxide

Carbon dioxide is used for a variety of applications including your bench-top incubators. In manufacturing, you use CO2 in fluid chromatography.  In wastewater treatment application, you need CO2 for self-buffered pH controls.
