  • Vitrification device for gametes or embryos
    Patent number: 11785941
    Abstract: A vitrification device for gametes or embryos, wherein, the vitrification straw comprises: a loading rod, wherein the loading rod is a metal rod; a loading strip, wherein, the loading strip is connected with one end of the loading rod. According to the present invention, the loading rod is arranged as metal rod, which avoids embrittlement fracture caused by sudden temperature change when the loading rod is taken out of liquid nitrogen, moreover, the ice crystals that form on gametes or embryos when the loading rod floats out of the surface of liquid nitrogen, affecting the safety of gametes or embryos, the metal material used by this invention can increase the weight of the loading rod, preventing it from floating up in the liquid nitrogen, hence improve safety of gametes or embryos.
