Cryopreservation vitrification
WebRapid-i Vitrification System is an aseptic and closed system removing the concerns regarding potential contamination from liquid nitrogen during transport and storage. As the oocytes or embryos do not come in direct contact with liquid nitrogen, there is no need to sterilise liquid nitrogen. WebVitrification is an alternative to cryopreservation by freezing that enables hydrated living cells to be cooled to cryogenic temperatures in the absence of ice. Vitrification simplifies and frequently improves cryopreservation because it eliminates mechanical injury from ice, eliminates the need to …
