  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...

  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...

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...

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...
