Liquid Nitrogen Dewar for IVF & Cell Storage


When it comes to protecting irreplaceable biological samples embryos, sperm, oocytes, stem cells, and tissue the quality of your liquid nitrogen dewar can make all the difference. Whether you’re running a busy IVF clinic, a fertility research facility, or a hospital cell-banking programme, choosing the right cryogenic storage dewar is one of the most critical decisions you’ll make.

The Cryolab CryoNest® Series has been purpose-built to meet the demands of modern biological laboratories combining exceptional LN2 storage capacity, innovative proprietary rack systems, and long-term reliability in a compact, cost effective design that outperforms any standard 20L liquid nitrogen dewar or 50L liquid nitrogen dewar on the market.

What Is a Liquid Nitrogen Dewar?

A liquid nitrogen dewar also called an LN2 storage vessel, cryogenic dewar, or nitrogen storage dewar is a specialised, vacuum-insulated container designed to safely hold liquid nitrogen at ultra-low temperatures (−196°C). In IVF and reproductive medicine, these vessels are used for the long-term cryopreservation of biological samples including embryos, sperm, eggs (oocytes), and tissue biopsies.

Unlike standard industrial dewars, biological-grade LN2 storage tanks must offer precise temperature stability, flexible racking systems, and robust clinical safety certifications — requirements that sit at the heart of the CryoNest® design philosophy.

CryoNest® Series: High-Capacity LN2 Storage Vessels

Cryolab CryoNest Series of Racked LN2 Storage Tanks are designed to optimise efficiency, storage capacity, and ease of use. The Series includes three distinct models, each with a compact and versatile design that enables easy sample access, maximises space, and dramatically reduces the storage cost per patient:

  • CryoNest XL ideal for growing clinics ready to move beyond a standard 20 litre liquid nitrogen dewar
  • CryoNest XXL the most popular model, offering an exceptional capacity-to-footprint ratio
  • CryoNest XXXL the ultimate large liquid nitrogen dewar for high-volume IVF and cell storage programmes

All three models range from 95 to 175 litres in size capable of holding significantly more samples than a standard 47L tank — yet they maintain an almost identical footprint, with much longer hold times.

Why Upgrade from a Standard 20L or 50L Liquid Nitrogen Dewar?

Many IVF labs start out with a 20 litre liquid nitrogen dewar or a 50L liquid nitrogen dewar — practical for smaller volumes, but quickly outgrown as patient numbers rise. Frequent LN2 refills increase costs, and limited rack capacity creates storage headaches. The CryoNest® Series solves all of these challenges in one step:

  • Far greater sample capacity – store significantly more samples than a standard 47L or 50L dewar
  • Longer hold times – reduce the frequency and cost of liquid nitrogen refills
  • Lower storage cost per patient – a major operational saving for busy IVF clinics
  • Same compact footprint – no need to reconfigure your existing lab layout
  • Compatible with all sample types – straws, goblets, cryotubes, ampoules, blood bags, and well plates

Proprietary Racking: The Most Versatile Cryogenic Storage Dewar System Available

One of the defining features that sets the CryoNest® apart from other liquid nitrogen dewar for cell storage options is its proprietary internal rack system — lightweight, retractable, and designed for effortless sample access even during busy clinic sessions.

The racks are compatible with a wide range of storage configurations, enabling laboratories to store:

  • Straws in daisy goblets or on canes
  • Ampoules
  • Cryotubes in boxes
  • Blood bags
  • Well plates

This flexibility makes the CryoNest® one of the most versatile and cost-effective dewar nitrogen storage vessels in the world, meeting the needs of IVF clinics, blood banks, tissue banks, stem cell facilities, and research laboratories equally well.

Certified Quality & Industry-Leading Warranty

Every CryoNest® LN2 storage tank comes with the certifications and guarantees you need when protecting irreplaceable samples:

  • UKCA & CE marking – fully compliant for UK and European clinical environments
  • Industry-leading 5-year vacuum warranty – the best-in-class standard for LN2 storage vessels
  • 2-year parts warranty – complete peace of mind on all components
  • Optional roller bases – available for all three models for easy repositioning

Who Is the CryoNest® Series Designed For?

CryoNest® is the ideal liquid nitrogen dewar for cell storage across a wide range of professional settings:

  • IVF & fertility clinics (NHS and private) – maximise sample storage per square metre
  • Hospital cell banking units – UKCA/CE-certified cryogenic storage dewar solutions
  • Stem cell & tissue banks – flexible racking for multiple container types
  • Research institutions – high-capacity LN2 storage with minimal maintenance overhead

Frequently Asked Questions: Liquid Nitrogen Dewars for IVF & Cell Storage

What is the difference between a 20L and a 50L liquid nitrogen dewar?

A 20 litre liquid nitrogen dewar suits smaller labs or transport needs, while a 50L liquid nitrogen dewar offers greater hold time and capacity. Both are significantly outperformed by the CryoNest® Series, which starts at 95L and stores far more samples per litre of LN2 used – at a lower cost per patient.

Can I store embryos and sperm in the same liquid nitrogen dewar?

Yes. CryoNest’ s flexible racking accepts multiple sample types simultaneously – embryos in straws or vitrification devices, sperm in high-security straws, and oocytes — all within the same cryogenic storage dewar.

What hold times do the CryoNest® LN2 storage tanks offer?

CryoNest Series offers significantly longer hold times than standard 20L or 50L liquid nitrogen dewars, reducing refill frequency and lowering operational LN2 costs. Contact Cryolab for model-specific technical specifications.

Is a liquid nitrogen dewar the same as a cryogenic dewar?

Yes the terms are interchangeable. A liquid nitrogen dewar, cryogenic storage dewar, LN2 vessel, and dewar nitrogen storage container all refer to the same type of vacuum-insulated vessel designed for ultra-low temperature biological storage.

What is a liquid hydrogen dewar vs a liquid nitrogen dewar?

A liquid hydrogen dewar stores liquid hydrogen, typically used in industrial and aerospace applications. A liquid nitrogen dewar is used in biological and medical settings for cryopreservation. For IVF and cell storage, liquid nitrogen dewars are the standard.

Do Cryolab dewars comply with UK regulations? Yes. All CryoNest® tanks carry full UKCA marking for the UK market and CE marking for Europe, ensuring compliance with medical device, clinical, and health & safety regulations.

Why the Right Vit Kit Changes Everything in the Lab

  Vitrification sits at the heart of assisted reproductive technology, giving embryologists a dependable way to preserve oocytes, embryos and sperm with high survivability after warming. The method is widely recognised as one of the most effective cryopreservation techniques in reproductive medicine, as outlined in general reference sources such as the vitrification overview on Wikipedia:   https://en.wikipedia.org/wiki/Vitrification What this really means is that both the method and the equipment must work in harmony. The CBS High Security Vit Kit has become a familiar choice in IVF labs for exactly that reason. It’s available as sperm vitrification kits, oocyte vitrification kits, vitrification oocyte kit options and full embryo vitrification kits, giving teams the flexibility to match tools to their workflow. Components and design A standard vit kit includes a high-security straw, a capillary tube with a pre-formed gutter, coloured handling rods and a plastic insertion devi...
