The auxiliary container bench to stock liquid nitrogen during the procedure of vitrification of oocytes and embryos and highly

摘要

The present invention relates to a thermos flask used for storage in liquid nitrogen deamostras vitrified oocytes and embryos.Before its final storage in bottles containing the cryogenic liquid.This vessel arises as an alternative to currently used methods, which are difficult to clean, occupy space or you 'IL end up wasting the cryogenic liquid for rapid evaporation.The thermos flask is composed internally of the proposed styrofoam material that keeps for a long time the cryogenic liquid without evaporating.And out of stainless steel or plastic resistant to low temperatures, which facilitates its asepsis.The box is compact, and it does not occupy much space in the chapels of laminar flow and stands in general.The housing has a fitting system where a support composed of stainless steel or plastic resistant to low temperatures will be attached.This support is used paramanter tubes 15 and 50 milliliters inclined.The tubes have holes which allow the entrance of cryogenic liquid.What keeps the samples properly cryopreserved and makes the tube does not bóie in the canister of the nitrogen tank liquid.Accordingly, the present invention is a practical alternative for vitrification of oocytes and embryos.
