It is used for blastocyst 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 freezing recovery culturing liquid droplet has a circle area, each area has a slight undercut; (3) Add corresponding blastocyst culturing liquid droplet into the area, which can 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 blastocyst formation efficiency; ƒSingle dish bottom is conducive to laser assisted shrivel before blastocyst freezing.
