It is used for cleavage stage embryo culturing; （1）The dish marks numbers, each number matches with corresponding freezing recovery culturing liquid droplet, easy to identify, no need other mark in the bottom of the dish; （2）Each placed cleavage stage culturing liquid droplet has a circle area, each area has a slight undercut; （3）Add corresponding blastocyst culturing liquid droplet into the area, which prevent the droplet compatible by shaking at droplet preparation、covering oil & transfer process. Unique double dishes design:Can reduce amount of using mineral oil;‚Can prevent an overflow of mineral oil at move process, which affect the embryo growth & development; ƒSingle dish bottom is conducive to cleavage stage embryo assisted hatching.
