For standarised vitrification
with high-quality results
Vitrification is the most up to date and effective method of freezing oocytes and embryos, regardless of stage. Talk to embryologists about manual vitrification and they will readily agree that the process can be tedious and time-consuming. There is a long learning curve, skills need to be maintained and intense focus is required by the embryologist.
Gavi®, the world’s first automated vitrification instrument, was designed by embryologists who wanted better control over the variables involved in manual vitrification – temperature, embryo handling, cryoprotectant concentrations and balancing equilibration/vitrification timing. Their aim was stage specific, controlled vitrification performed in a standardised way every single time – and they were successful.

Precision and Consistency in Embryo Vitrification and Storage
Created after four years of intensive development, Gavi® is the first technology to automate the critical equilibration step, helping to standardise the complex vitrification process.
Gavi® approaches vitrification in an entirely new way, helping to achieve consistent high-quality results every time.
Consistent and reproducible process
Unique Gavi® Pod
Precise equilibration process
High-quality results
A controlled, closed-system enviroment
Short learning curve
Gavi® helps you to achieve optimal vitrification conditions
There are many critical variables within the vitrification process that can impact embryos’ survival post-thawing – from achieving the right balance between the cryoprotectant concentrations and flow rates to reducing manual handling.

The Gavi® Family
Gavi® comes with a range of supplied accessories including:
Gavi® Operating Tray
Holds the Gavi® Medium Cartidge, Cassete and Tip & Seal Catridge.
Gavi® LN2 Bucket
Holds liquid nitrogen for the final stage of the vitrification process.
Gavi® Tweezers
For a secure grasp of the Gavi® Cassette when dunked into Gavi® LN2 Bucket.
Consumables used with Gavi®
Gavi® Tip & Seal Cartridge
Holds the disposable pipette tip and Pod lid seal.
Gavi® Medium Cartridge
Contains the Gems® vitrification solutions.
Gavi® Cassette
Holds up to four Pods at once, allowing you to vitrify four blastocysts or 8 oocyte/cleavage stage embryos simultaneously
Gavi® Pod
The Gavi Pod is a container with the capacity to hold two oocytes or zygote/cleavage stage embryos or one blastocyst stage embryo during the vitrification, storage and warming processes.
Accessories used with Gavi®
Gavi® Working station
Holds the Gavi® cassette within LN2 to facilitate the removal of single Pods for thawing.
Gavi® Storage Dividers
For use with cryogenic storage canisters, to provide orderly organisation of Cassette and Pods by patient. Available in round or rectangular form.
Greater consistency of results compared to manual methods.
To evaluate the potential improvements from a training and standardisation perspective, survival results across freeze scientists for the early stages of implementation at all Genea labs of Gavi® (2015-2017) and Cryotop® (2009-2010) were retrospectively analysed.
When comparing blastocyst survival, Gavi® reduces the variability of results among embryologists of different experience levels with a particular device.
Gavi® requires reduced technical skill compared to manual vitrification methods, with shorter learning curves, and a reduced time to achieve vitrification competency
Gavi® clinical outcomes:
Evidence lies in the results
Any implementation period gives an opportunity to analyse data and so we looked back. It became obvious how easy Gavi® was to learn and how quickly embryologists were able to achieve benchmark results compared to the manual method.
When analysing the early-stage implementation data for the two techniques we found using Gavi® there was a reduction in the variability of results between embryologists and the period between basic vitrification competency to aspirational competency was reduce.
