DEVICE FOR vitrification of oocytes and mammalian embryos

摘要

The invention relates to biotechnology and can be used for vitrification of oocytes, zygotes and embryos of mammals in the early stages of development, particularly cattle embryos produced in vitro. Summary of the utility model: the device comprises two parts, namely a carrier with an open surface for placing the embryo into a microdrop vitrification solution and protective cover thereto. The device is made from standard straws to 0,25 (mini straws) and 0.5 ml (medium straws), used for the cryopreservation of biological material, and standard plugs (plugs) to 0.25 ml straws. The carrier is a closed stopper having a free end and trimmed to about half the length of an oblique cut length of about 1 cm by 0.25 ml straws, which walls have a through-hole and flattened portion immediately adjacent the inner edge portion of gag. Straw 0.5 ml is used as a cover for the carrier-polusolominki.
