The Need for Nitrogen in Portland Pharmaceutical and Biotech Applications


We’ve talked before about the uses Nitrogen gas (N2) in the food and beverage industry. As you may gather, though, given the prevalence of this gas in our atmosphere, nitrogen has many other equally advantageous uses. Cryo-Source, your Portland PurityPlus® Partner, is particularly active, for instance, in providing nitrogen for the pharmaceutical and biotech industries.

Pharmaceutical manufacturers and biotech firms generally use nitrogen in a procedure known as blanketing to help preserve or enhance the quality of packaged medicines, medical supplies, medical devices, and biological samples. In blanketing, nitrogen ends up supplanting oxygen prior to the packaging being sealed. This eliminates the potential for oxidation, contamination, degradation, and other detrimental side effects resulting from oxygen reacting with other kinds of materials. Nitrogen sustains product or sample sterility and integrity. It also helps preserve and protect products during transport. Specimen containers, blood supplies, and doctor’s test kits are examples of products most often packaged with nitrogen.

Nitrogen being a safe, inert gas, it’s employed quite commonly as well to transfer liquid and powdered pharmaceutical materials, which can be unsafe if handled negligently.

Besides this, nitrogen blanketing is employed to diminish the presence of oxygen – and thus the possibility of fire or explosions – in environments where combustion is a constant concern. Pharmaceutical manufacturing facilities, medical laboratories, and hospitals routinely employ nitrogen generators to govern the level of oxygen in the workplace seeing as how generators are more simply and accurately controlled than high-pressure gas cylinders.

Meeting the pharmaceutical and biotech industries’ need for ultra high-purity and ultra carrier-grades of nitrogen here in Portland has been a top priority at Cryo-Source from the first.
