Most people think IVF is about doctors and operating theatres. The reality is that the outcome of every IVF cycle depends heavily on what happens in the laboratory, specifically on the precision of the cryogenic equipment used to freeze, store, and transport genetic material.
Here is a plain English breakdown of the core equipment stack.
Controlled rate freezers vs vitrification
Two approaches to cryopreservation. Controlled rate freezers cool samples on a programmable temperature curve, slow and precise. Vitrification is ultra rapid cooling, dropping samples to a glassy state before ice crystals can form. Both are used in clinical IVF. Vitrification has become the dominant method for oocytes and embryos.
Storage dewars
Cryogenic dewars hold samples at minus 196 degrees Celsius using liquid nitrogen. No electricity required for temperature maintenance, which removes power failure as a risk factor. The engineering challenge is minimising liquid nitrogen evaporation while maximising storage capacity and organisation.
Dry shippers
For transport, dry shippers are insulated vessels that hold liquid nitrogen in absorbent material, releasing vapour phase nitrogen to maintain ultra low temperatures without free liquid. CryoStork dry shippers from Cryolab are used by IVF clinics and sperm banks worldwide for specimen transport.
The consumables layer
On top of hardware sits a consumables layer. Vitrification straws (open or closed high security systems), cryocanes, goblets, canisters, and labelling systems. Every item must be quality assured and traceable. All Cryolab consumables are UKCA and CE marked, backed by ISO 9001 certification.
Bringing it together
Equipping an IVF laboratory requires a coherent approach where every link in the cryogenic chain, from freeze to storage to transport, maintains unbroken ultra low temperature. Cryolab has spent over 40 years helping UK fertility clinics build and maintain that chain.
