Cryopreservation equipment in an IVF laboratory covers four functional categories: freezing systems, storage vessels, consumables, and monitoring infrastructure. Each category must be sourced to the appropriate clinical standard for use with human gametes and embryos under an HFEA licence.
Freezing systems include controlled rate freezers, which cool samples at a defined programmable rate typically between minus 0.3 and minus 10 degrees Celsius per minute using a computer-controlled liquid nitrogen injection system, and vitrification workstations equipped with liquid nitrogen-cooled handling surfaces. Vitrification has largely replaced controlled rate freezing for oocytes and embryos in UK clinical practice, though controlled rate freezing remains the standard for sperm and certain tissue types.
Storage vessels include open-necked liquid nitrogen dewars for short-term working stock and long-term vapour or liquid phase storage dewars for clinical sample repositories. The CryoNest range from Cryolab is designed for IVF clinical storage, featuring low evaporation rates, organised racking systems, and vacuum integrity backed by a multi-year warranty. Consumables include vitrification carriers and straws, cryocanes, goblets, canisters, cryovials, and sample identification labels rated to minus 196 degrees Celsius. All consumables used in a licensed UK IVF unit must be UKCA and CE marked where applicable.
Monitoring infrastructure includes continuous temperature and liquid nitrogen level monitors with remote alarm capability, calibrated thermometers, and documented maintenance records. The HFEA Code of Practice Section 17 sets out specific requirements for equipment maintenance and quality management in licensed storage facilities. A full cryopreservation equipment range for IVF clinics is available from Cryolab at cryolab.co.uk.
