The Need for Nitrogen in Pharmaceutical and Biotech Applications


We’ve already discussed the uses Nitrogen gas (N2) in the food and beverage industry. As you might expect, though, given the prevalence of this gas in our atmosphere, nitrogen has lots of other equally beneficial uses. PurityPlus® and its 150 Partners nationwide are particularly active, for instance, in supplying nitrogen to the pharmaceutical and biotech industries.

Pharmaceutical manufacturers and biotech firms typically use nitrogen in a process called blanketing to help preserve or improve the quality of packaged medicines, medical supplies, medical devices, and biological samples. What blanketing does is displace oxygen with nitrogen before the packaging is sealed. This eliminates the potential for oxidation, contamination, degradation, and other harmful side effects resulting from oxygen reacting with various other materials. Nitrogen maintains product or sample sterility and integrity. It also helps preserve and protect products in shipment. Specimen containers, blood supplies, and doctor’s test kits are examples of products most often packaged with nitrogen.

Because 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 improperly.

Finally, nitrogen blanketing is used to reduce the presence of oxygen – and thus the threat of fire or explosions – in environments where combustion is a constant concern. Pharmaceutical manufacturing facilities, medical laboratories, and hospitals routinely employ nitrogen generators to control the level of oxygen in the workplace as generators are more easily and precisely controlled than high-pressure gas cylinders.

Satisfying the pharmaceutical and biotech industries’ need for ultra high-purity and ultra carrier-grades of nitrogen has been a top priority at PurityPlus® from our founding. No matter where you are, you can talk easily with one of our specialty gas experts to help identify which nitrogen product is most suitable for your application.
