The Need for Nitrogen in Fresno Pharmaceutical and Biotech Applications


We’ve written before about the uses Nitrogen gas (N2) in the food and beverage industry. As you may expect, though, given the commonness of this gas in our atmosphere, nitrogen has many other equally advantageous uses. Fresno Oxygen & Welding Supplies/Barnes Welding Supply, your Fresno PurityPlus® Partner, is especially active, for instance, in producing nitrogen for the pharmaceutical and biotech industries.

Pharmaceutical manufacturers and biotech firms most often employ nitrogen in a practice dubbed blanketing to help maintain or boost the quality of packaged medicines, medical supplies, medical devices, and biological samples. What blanketing does is displace oxygen with nitrogen just before the packaging is sealed. This removes the potential for oxidation, contamination, degradation, and other detrimental side effects resulting from oxygen reacting with various other materials. Nitrogen safeguards 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.

Since nitrogen is a safe, inert gas, it’s used quite often as well to transfer liquid and powdered pharmaceutical materials, which can be unsafe if handled thoughtlessly.

Besides this, nitrogen blanketing is employed to diminish the presence of oxygen – and therefore the threat of fire or explosions – in conditions where combustion is a persistent concern. Pharmaceutical manufacturing facilities, medical laboratories, and hospitals customarily make use of nitrogen generators to control the level of oxygen in the workplace seeing as how generators are more readily 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 here in Fresno has been a main concern for us at Fresno Oxygen & Welding Supplies/Barnes Welding Supply from the first. Contact us today and talk with one of our specialty gas specialists to help verify which of our nitrogen products is most suitable for your application.
