Cryogenic Tanks and Liquid Nitrogen Storage

LONDON - Jan. 13, 2026 - PRLog -- Maintaining ultra-low temperatures is critical in cryogenic storage. Eggs, sperm, embryos, and other biological samples remain viable only when stored consistently at -196 °C. Even small temperature fluctuations can compromise years of research or clinical work. Across the UK, laboratories and fertility centres rely on cryogenic tanks, LN2 tanks, and dewars to keep specimens safe.

What Are Cryogenic Tanks?

A cryogenic tank is a specialised vessel for storing biological materials at extremely low temperatures using liquid nitrogen (LN₂). These tanks preserve samples long-term by maintaining stable temperatures below -196 °C.

Cryolab's CryoNest® range includes high-quality aluminium and stainless steel tanks designed for minimal nitrogen evaporation. Whether your lab needs a single cryogenic tank or multiple LN2 storage vessels, CryoNest® offers solutions tailored to any workflow.

Dewars and Portable Cryogenic Storage

Liquid nitrogen dewars are versatile for labs requiring both portability and reliability. Sizes range from 1.5 L for compact storage to 20 L or larger for mid- and high-volume operations.

• Small labs benefit from compact dewars that save space.
• Medium-scale labs use 20 L LN2 tanks for routine storage.
• Large facilities invest in high-capacity cryogenic tanks for long-term preservation.

Dewars also work with storage canisters and racks for organised sample management. Portable dewars and dry shippers allow safe transport without compromising cryogenic conditions.

Applications of Cryogenic Tanks and Dewars

Cryogenic tanks, LN2 tanks, and storage canisters are used across multiple fields:

• Fertility clinics: Eggs, sperm, and embryos.
• Biobanks: Cell lines, tissues, and biological samples.
• Research laboratories: Experimental materials and study specimens.
• Pharmaceuticals: Temperature-sensitive compounds.

Correct use of cryogenic tanks and dewars ensures valuable samples remain secure and viable.
