CryoStork vs CryoNest — Which Cryogenic Vessel Does Your Laboratory Actually Need?

Image
It is one of the most common questions in IVF and research laboratory procurement — what is the difference between a liquid nitrogen dry shipper and a cryogenic storage vessel, and which one do you need? The answer is simpler than most people expect. The CryoNest® is your on-site storage solution. The 95-litre CryoNest® XL holds significantly more samples than a standard 47-litre tank without increasing your laboratory footprint, with extended hold times and easy sample access built in. It stays in your lab. The CryoStork is your transport solution. Available in 2 to 10 litre capacities, it absorbs liquid nitrogen into its inner lining — meaning no free liquid, no spillage risk, and full IATA compliance for international air freight. It leaves your lab with your samples. The simplest rule: samples staying in your facility go in a CryoNest. Samples leaving your facility go in a CryoStork. Cryolab supplies both ranges worldwide to IVF clinics, fertility laboratories, research facilities ...

Complete Guide to Oocyte Vitrification UK | Cryolab

Image
Oocyte vitrification is the gold standard egg freezing technique used by IVF clinics across the UK. Using ultra-rapid cooling at -196°C, vitrification achieves post-thaw survival rates of 80-95% — far superior to older slow-freezing methods. Key equipment for UK IVF labs includes validated vitrification kits such as the CBS HSV Kit, CBS High Security Straws for closed system vitrification, cryogenic storage dewars, and full cryogenic labelling systems for HFEA traceability compliance. All UK fertility clinics performing oocyte vitrification must be HFEA licensed. Closed vitrification systems are increasingly required under HFEA infection control guidelines. Cryolab supplies a complete range of vitrification equipment and IVF consumables to fertility clinics and research laboratories across the UK. Read the complete guide including open vs closed systems comparison, HFEA regulations, post-thaw survival rates, FAQ and equipment recommendations: Full guide → cryolab.co.uk/complete-guide-o...

Cryogenic Accessories & Supplies Consumables

Image
  Walk into any serious life science, biobank, or industrial laboratory, and you’ll see that the cryogenic workflow is much more than a single piece of equipment. It is an ecosystem, held together by carefully chosen cryogenic accessories and consumables that make safe, repeatable, and compliant low-temperature work possible. Quick Definition:   “ Cryogenic “  refers to temperatures below −150°C (−238°F). At these extremes, standard lab materials behave very differently, which is why specialist accessories and consumables are essential. Understanding Accessories vs. Consumables Cryogenic accessories are durable, reusable items that support operations over time — insulated gloves, face shields, liquid nitrogen dispensing canes, dewar vessels, storage racks, and transfer equipment. Cryogenic  supplies consumables  are items that are used up and replaced regularly, including cryovials, straws, labels, O-rings, and disposable PPE such as aprons and sleeve protectors...

What Every IVF Lab Should Know About Sperm Straws

Image
  When it comes to cryopreservation in an IVF setting, there is no room for compromise. The straws used to store embryos and sperm are not mere consumables they are the last line of defence between a patient’s sample and the outside world. Choosing the right ones matters enormously. This guide covers everything you need to know about high security straws for embryo and sperm storage: how they work, why the CBS design has become the industry benchmark, and what to look for when sourcing embryo storage straws in the UK. What Are High Security Straws? High security straws are specialised cryogenic tubes designed for the long-term storage of biological material — primarily embryos and sperm — in liquid nitrogen (LN2). Unlike standard open-ended straws, high security straws feature a hermetically sealed design that prevents cross-contamination between samples and eliminates the risk of LN2 ingress. This sealed construction is critical in a regulated IVF environment. The Human Fertilisat...

CryoStork Dry Shipper: Complete Guide to Pricing, Models & Cryogenic Transport

Image
  When it comes to the safe transport of biological samples at cryogenic temperatures, not all dry shippers are equal. Whether you are shipping embryos between fertility clinics, moving cell lines between research institutions, or transporting valuable biobank material across the country or overseas, you need a dry shipper you can trust absolutely. CryoStork® Series of Dry Shippers has been designed from the ground up for exactly this purpose delivering safe, secure, and efficient transportation of biological samples in the liquid nitrogen (LN₂) vapour phase. Available in a range of sizes from 2 litres up to the V10, there is a CryoStork dry shipper for every application and budget. This guide covers everything you need to know: how dry shippers work, what the CryoStork range offers, dry shipper price expectations, and how to choose the right model for your needs. What Is a Dry Shipper and Why Does It Matter? A dry shipper is a specialist cryogenic container designed to keep biolog...

Liquid Nitrogen Dewar for IVF & Cell Storage

Image
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...

Best Gloves, Cryo-Markers, Dipsticks and PPE | Cryolab

Image
Handling cryogenic materials demands specialised equipment to protect both staff and valuable samples. Cryogenic laboratory gloves and liquid nitrogen gloves provide the insulation needed to prevent frostbite and injuries while working with ultra-low temperature substances. Combined with face shields, lab PPE, and the Cryo-Apron 24″ X 42″ CA42, these gloves form a reliable safety barrier. Durable Cryomarkers for Lab Organisation Clear labelling is crucial in cryogenic environments.  Cryomarker  Fine Tip ensures permanent and legible marks on vials, tubes, and containers, even at extremely low temperatures. Available in black or assorted colours, these markers reduce the risk of sample misidentification and streamline lab organisation. Accurate Liquid Nitrogen Measurement with Dipsticks Maintaining correct liquid nitrogen levels is vital for sample preservation.  Dipstick  provides a safe, manual method to measure storage levels accurately. Many labs pair it with ultr...
