We are delighted to share some exciting news - a remarkable conservation charity working to cryopreserve the genetic material of endangered species before it is too late.  Nature's SAFE runs a frozen wildlife biorepository, safeguarding biological samples from some of the world's most threatened animals. The CryoStork® V10 will help them transport these precious specimens safely in the field, without the need for free liquid nitrogen.  In the words of our Director, Sian Louise Barker: "Their commitment to the conservation and long-term cryopreservation of endangered species is nothing short of inspiring."  If you are a partner, distributor, or organisation that works with cryogenic equipment and would like to explore supporting Nature's SAFE, please reach out to us or visit them directly. Every piece of equipment matters.   Learn more at cryolab.co.uk    #Conservation #EndangeredSpecies #Cryogenics #NaturesSAFE #CryoStork #Biodiversity 

  For decades, sperm motility has been assessed manually under a microscope. While this method is widely used, it has clear limitations. Human observation introduces variability, fatigue, and subjective interpretation. CASA systems have changed this by using imaging technology and software algorithms to analyse sperm movement objectively. These systems evaluate thousands of sperm in seconds, providing consistent and repeatable results. As IVF demands increase, automation is becoming essential for modern andrology laboratories. 👉 Read more: https://cryolab.co.uk/sperm-motility-analysis-equipment/

  If you're an embryologist, a fertility nurse, or a clinic manager who wants a clear explanation without the lecture, here it is. A vitrification carrier is the small device that holds an egg (or embryo) during the ultrarapid freezing process that is vitrification. The carrier matters because how quickly the sample cools determines whether ice crystals form. No crystals = surviving cells. The carrier needs to hold a tiny volume so the cooling is fast enough. The warming protocol is the carefully choreographed process of getting the egg out of vitrified storage and back to a state where it can be fertilised. You remove the cryoprotectants through a series of dilution steps while managing the osmotic shift to avoid rupturing the membrane. Do it wrong and the egg doesn't survive. Do it right and survival rates are consistently above 80%. The practical takeaway: use a matched vitrification and warming kit. The kits are designed and validated together. Mixing brands or improv...

  Let's be real: most people only google 'what is sperm cryopreservation' after a doctor has just mentioned it to them, which means they're probably sitting in a car park somewhere trying to absorb information quickly. So here's the clearest version possible. Sperm cryopreservation means freezing sperm cells in liquid nitrogen at -196 degrees Celsius so they can be stored and used later. Before freezing, the sperm is analysed (concentration, movement, shape) and mixed with a protective solution that stops ice crystals from destroying the cells. It's then cooled at a carefully controlled rate and stored until n eeded. Why does it matter? Because it lets people preserve fertility before chemotherapy, before deployments, before vasectomy, before the years when sperm quality naturally declines. Frozen samples stored properly can remain viable for decades. When it's time to use the sample, it's thawed, assessed again, and prepared for IVF, ICSI, or inse...

If you work in an IVF lab or manage a research facility with cryogenic storage requirements, you have probably stood in front of a liquid nitrogen vessel at some point and quietly wondered if there is something better out there. Spoiler: there usually is. Cryolab makes two distinct families of LN2 storage vessels, and they are built for quite different jobs. CryoNest® Series available in 95-litre (XL), 145-litre (XXL), and 175-litre (XXXL) configurations is for labs that need scale. High sample volumes, multiple clinicians accessing the vessel throughout the day, long-term storage of embryos, oocytes, and sperm across a large patient base. The proprietary internal rack system means up to 30 compartments of organised, accessible storage in a footprint that would surprise you. Explore it at cryolab.co.uk/product-category/storage-vessels/ CryoCan Series three models: the 30-6, 47-6, and 47-10 is for labs where compactness matters as much as capacity. The 30-litre CryoCan 30-6 fits i...

If you work in fertility medicine, cell banking, or biological research in the UK, you've probably wrestled with the question of which dry shipper to trust with your most critical samples. After looking at what's available from cheap imports to premium research-grade dry shippers — the CryoStork by Cryolab stands out for a few specific reasons that matter in clinical practice. First, the hold time is genuinely reassuring. Extended hold means extended margin for error when logistics go sideways (and they do). Second, IATA P650 compliance is properly documented — not just claimed. Third, and maybe most importantly for UK-based users: there's an actual support team you can reach who understands cryogenics, not just a returns portal. Dry shipper price will always be a factor in procurement decisions. But when the cost of a failed shipment can run to tens of thousands in lost samples, clinic liability, or patient harm the conversation changes. Worth enquiring: cryolab.co.uk
