Sample Storage in Liquid Nitrogen – Safe and Long-Term

Storing sensitive biological samples places high demands on temperature stability and safety. Using liquid nitrogen (LN₂) as a cooling medium allows cells, tissue and other biological materials to be preserved at cryogenic temperatures over long periods without compromising their structure or functionality. Axon Labortechnik offers cryogenic storage tanks in various sizes, along with matching interior equipment such as cryo boxes and rack systems for clear and efficient sample organization. Whether for small laboratory stocks or large sample collections in research, medicine and biotechnology, we help you find the right system for your specific needs.

Frequently Asked Questions about Sample Storage in Liquid Nitrogen

At what temperature are samples stored in liquid nitrogen?

Liquid nitrogen has a temperature of around −196 °C. In the vapor phase above the liquid nitrogen, temperatures typically range between −150 °C and −190 °C, which is sufficiently cold for many applications.

What is the difference between liquid-phase and vapor-phase storage?

In liquid-phase storage, samples are directly immersed in liquid nitrogen and reach the lowest possible temperature. In vapor-phase storage, samples sit above the liquid nitrogen level within the cold gas, reducing the risk of cross-contamination between samples at a slightly higher temperature.

Which samples are suitable for storage in liquid nitrogen?

Suitable materials include cell cultures, tissue samples, stem cells, germ cells, microorganisms and other biological materials that need to be preserved long-term for research, diagnostics or therapeutic applications.

How do I choose the right tank size for my needs?

The choice depends on the number of samples to be stored, the cryo box format used, and the desired holding time between refills. We're happy to provide individual advice to match capacity and space requirements to your needs.

How are samples organized within the tank?

Rack systems and cryo boxes allow samples to be stored in a structured, easily traceable way. Depending on the tank model, different rack and box formats are available, enabling clear management even of large sample volumes.
