A recently developed minimum volume, absorbent, vitrification device, the Kitasato Vitrification System gives excellent outcomes for in vitro produced bovine blastocysts.

Cryopreservation of embryos is a crucial component of current assisted reproductive technologies (ART). While the ART outcomes for many species have been greatly improved by the introduction of minimum volume vitrification devices, these devices can be difficult to handle and load. To reduce this problem, we recently developed a vitrification carrier which has a highly absorbent surface so that it simply and rapidly removes excess free vitrification solution from the specimen before the cooling step.
