Liquid nitrogen is a critical consumable for any IVF laboratory. Unlike most laboratory consumables, a disruption in nitrogen supply is not simply inconvenient. It is a patient safety issue. Storage dewars that are not topped up regularly will eventually reach low nitrogen levels and continuous monitoring alarms will trigger.

For UK IVF clinics, the choice of liquid nitrogen supplier involves several considerations.

Medical or research grade nitrogen is the appropriate specification for IVF use. Medical-grade liquid nitrogen is typically specified at a purity of 99.998 percent or higher.

Supply reliability matters enormously. A supplier who can guarantee delivery within a defined window, including contingency arrangements for delivery failures, is preferable to one whose service is inconsistent. Ask prospective suppliers specifically what their contingency is if the scheduled delivery cannot be made.

Contract terms should cover delivery frequency, minimum and maximum quantities, emergency top-up arrangements, and the specifications of the nitrogen being supplied. Most clinics top up on a weekly or fortnightly schedule depending on their consumption.

Maintain a minimum buffer. Most cryogenic equipment specialists recommend maintaining at least two weeks of buffer nitrogen supply capacity across your storage dewars so that even a delivery gap does not bring any dewar to a critical level.
