The Need for Nitrogen in Indianapolis Pharmaceutical and Biotech Applications


We’ve previously covered the uses Nitrogen gas (N2) in the food and beverage industry. As you may figure, though, considering the commonness of this gas in our atmosphere, nitrogen has all kinds other equally advantageous uses. American Welding & Gas, Inc., your Indianapolis PurityPlus® Partner, is particularly active, for instance, in supplying nitrogen to the pharmaceutical and biotech industries.

Pharmaceutical manufacturers and biotech firms most often employ nitrogen in a practice known as blanketing to help maintain or upgrade the quality of packaged medicines, medical supplies, medical devices, and biological samples. Essentially, blanketing replaces oxygen with nitrogen immediately before the packaging is sealed. This removes the potential for oxidation, contamination, degradation, and other detrimental side effects resulting from oxygen reacting with other types of materials. Nitrogen maintains product or sample sterility and integrity. It also helps preserve and protect products during shipping. Specimen containers, blood supplies, and doctor’s test kits are examples of products commonly packaged with nitrogen.

Given that nitrogen is a safe, inert gas, it’s used quite commonly as well to transfer liquid and powdered pharmaceutical materials, which can be hazardous if handled inappropriately.

Besides this, nitrogen blanketing is used to diminish the presence of oxygen – and therefore the possibility of fire or explosions – in conditions where combustion is a real concern. Pharmaceutical manufacturing facilities, medical laboratories, and hospitals as a matter of course use nitrogen generators to control the level of oxygen in the workplace because generators are more easily and accurately controlled than high-pressure gas cylinders.

Satisfying the pharmaceutical and biotech industries’ need for ultra high-purity and ultra carrier-grades of nitrogen here in Indianapolis has been a prime concern for us at American Welding & Gas, Inc. from the get-go.
