Ultra rapid vitrification for improved post-thaw results

VitMaster is a simple to use, portable device which delivers ultra rapid vitrification of material for improved post-thaw results over traditional LN2 plunging techniques.

It is designed for embryos, oocytes and other cell types, and is used in human and animal assisted reproductive technology fields, as well as other biological facilities.

VitMaster minimises cell damage during cryopreservation by safely vitrifying cells at a cooling rate up to 52x faster than traditional plunging, enabling high post-thaw survival rates for sensitive cells including oocytes and embryos at all stages of development.

Straws, even in sealed form, can be cooled safely with an increased cooling rate

VitMaster’s faster cooling rate offers key benefits:

Increased post-thaw survival

An increased probability of cells vitrifying successfully, without the formation of damaging ice crystals.

Reduced chilling injury

A faster passage through the dangerous temperature zone means lipid phase transition is reduced, allowing sensitive cells, including embryos at all stages of development, to be successfully cryopreserved.

Reduced toxicity

Cryoprotectant concentration can be reduced resulting in less toxicity and maximised post-thaw viability.

Larger volumes

Vitrification can be achieved with larger volumes than with traditional plunging.

Consistency of freezing and repeatability

Avoiding traditional system ‘gas pocket’ boiling means results are consistent and repeatable.

Enabling use of a sealed straw system

→ No contamination – elimination of potential liquid nitrogen contamination
→ Safer – no risk of losing material
→ Simpler – preparation and storage of samples are made easier
