To achieve the above object, the utility model discloses carry out improvement optimization to thawing apparatus, the utility model relates to a biological sample device unfreezes contains: a constant temperature water bath comprising: the heat insulation outer shell layer is arranged on the outer surface layer of the constant-temperature water bath; the groove body is arranged in the heat insulation shell layer and is coated by the heat insulation shell material, wherein the edge of the groove body is provided with at least one upper bulge and at least one lower concave slot; and a control box comprising: a heating line for heating and maintaining the temperature of the tank body; the circulating pump is used for driving water in the tank body to flow for heat convection; and the thermometer is used for measuring the environmental temperature of the tank body.

The utility model discloses biological sample device unfreezes still contains the display for show this biological sample's that unfreezes device temperature.

The utility model discloses biological sample device unfreezes still contains biological sample cryovial save set, and biological sample cryovial save set contains a plurality of connection devices for bear the weight of the tubulose container of depositing biological sample, wherein this connection device contains: at least one convex tenon; each connecting device is assembled with the corresponding concave tenon through the convex tenon; a plurality of tubular container placing grooves which are arranged in each connecting device at intervals and are used for placing the plurality of tubular containers; and a plurality of combining clamps, each combining clamp is arranged below each connecting device and extends inwards from the lower edges at the two sides of each tubular container placing groove to fix each tubular container.

The utility model provides a connecting equipment, wherein this cell body of this biological sample device that unfreezes has protruding and at least one concave slot in at least one, and the epirelief card tenon and the concave card tenon butt joint that correspond a plurality of connecting equipment respectively for it is fixed with this a plurality of connecting equipment butt joints.

Through the utility model discloses a convex-concave trip of connecting device and thawing apparatus's last arch and concave slot intercombination can be fixed in the cell body with bearing precious biological sample and be heated evenly, can be applied to the tubulose biological sample of multiple partial shipment, contain animal cell, animal stem cell, respiratory secretion, oral cavity mucous membrane liquid, tear, excrement and urine, urine and environmental sample.
