Maximise cryosurvival and secure workflows
To be successful with vitrification and exert minimal effect on cell viability, a balance between cryoprotectant concentration, cooling and warming rates as well as volume is necessary.
Working together for you
Our solutions puts you in control. The method, media, device and accessories are all you need to simplify your workflow – from vitrification and storage to warming of oocytes as well as embryos.
Media for every need
We provide media for vitrification and warming of all stages, from oocytes to blastocysts.
Both vitrification and warming are performed at physiological temperature (37°C). This helps to maintain the spindle integrity and viability of oocytes and embryos. Working at physiological temperatures shortens the vitrification time and minimises exposure to cryoprotectants and their potential toxic effects.
Vitrify with confidence
Rapid-i™ is a unique vitrification device. After loading of the embryos onto the Rapid-i, the device is inserted into a pre-cooled RapidStraw™. The air inside the straw is super-cooled by the surrounding liquid nitrogen and the vitrification occurs instantly.
Sealing of the straw is performed after vitrification which makes it easier for the operator to perform the critical dehydration steps of vitrification within the important time frames. When the embryos are to be warmed, the RapidStraw is cut and the Rapid-i retrieved without any contact with surrounding materials, allowing for safe aseptic handling.
Everything in one place
The Rapid-i Vitrification System is an integrated, convenient and closed system for vitrification.
The device, media and supporting accessories in the system are developed to function together.
Colour coded straws
To simplify identification and cryostorage management, the Rapid-i straws are available with five different colour codes; blue, green, red, yellow and transparent.
Work with convenience, speed and stability

Vitrify at physiological temperature
RapidVit™ and RapidWarm™ media are used at 37˚C to maintain physiological temperature during dehydration and re-hydration procedures. Read a blog post on why 37⁰C is the optimal temperature for vitrification.
Easy handling of oocytes and embryos
Loading the Rapid-i is as simple as it is smart. By holding embryos with surface tension in a defined and minute volume, vitrification in super-cooled air occurs instantly without contact with liquid nitrogen. During warming, oocytes and embryos come off easily into the warming solution. We have collected our best tips & tricks for successful vitrification in a blog post.
Numerous publications show that Rapid-i Vitrification System provides excellent outcomes after vitrification of all stages, from oocytes to blastocysts. Independent published studies show that Rapid-i Vitrification System performs equally well as open vitrification systems and provides safe storage. 1,2
