Overview

What liquid nitrogen is, and why the grade matters

Liquid nitrogen is nitrogen held at around minus 196 C, cold enough to freeze most things on contact and compact enough that one vessel holds what would otherwise take a wall of cylinders. It is the same inert gas as the compressed product, delivered in a form that makes volume affordable.

Customers move to liquid for one of two reasons. Either they need the cold itself, for cryopreservation, food freezing or shrink fitting, or they need so much nitrogen gas that filling and swapping cylinders has become the real cost. In the second case the vessel simply vaporises back to gas at the point of use.

We deliver liquid nitrogen in vessels and tankers across Bhiwadi, Delhi NCR, Rajasthan, Haryana and the wider industrial belt, with vessel size matched to your actual consumption and route planning that accounts for normal evaporation loss rather than ignoring it.

Applications

Where liquid nitrogen is used

CryopreservationStorage of biological samples, cultures and semen at cryogenic temperature.
Food freezingCryogenic freezing, crust freezing and chilling in food processing.
Inerting at volumeVaporised back to gas for continuous blanketing and purging duty.
Shrink fittingCooling components for interference fits in engineering assembly.
Laboratory coolingCold traps, sample preparation and instrument cooling.
Bulk gas supplyOn site vaporised supply where cylinder handling no longer keeps up.
Handling

Handling and safety

Liquid nitrogen causes severe cold burns on contact and expands to a very large volume of gas as it warms, displacing oxygen in an enclosed space. Use insulated gloves and a face shield, never seal it in a closed container, and keep storage and decanting areas ventilated with oxygen monitoring where appropriate.
