To achieve the above purpose, the technical solution of the present invention is:

A kind of biological sample transfer tank comprising: tank body, thereon end opening；Cover assembly is set to the tank body opening Place；It include: fixed ring, lower end surface sets the annular groove planted for the tank body upper end, the nearly centre bore two in fixed ring upper surface Side sets hook ring, and fixed ring upper surface outer rim sets location hole；Fixed ring outer wall top is set with respect to the other two sides of two hook rings Holding tank；Fixed ring outer wall lower part circumferentially sets step；Lid, lower end surface center setting one and the fixed ring centre bore For the boss matched as thermal insulator, lid answers the two sides of boss to set through-hole；Lid upper surface sets and connects the two through hole, mentions for placing The U-shaped groove of hand sets portable slot in the middle part of U-shaped groove；Several positioning are circumferentially all provided on the outside of the thermal insulator of the lid lower end surface Pin, and it is inserted in the location hole of fixed ring upper surface outer rim；Handle is in U-shape, and is set in the portable slot, handle two End is equipped with hook portion, and card hole is set on the handle above hook portion, and handle passes through card hole by shaft and is movably connected on the logical of the lid Hole, the hook portion are connected to the hook ring of the fixed ring upper surface centre bore two sides；Grillage, comprising: ontology is opened for about one Mouthful box body, inner wall lower circumferentially projection for place freezing storing box annular convex platform；It symmetrically erects ontology upper surface opening two sides Straight setting pallet distance post；The other two sides of grillage lower end surface opening are symmetrically vertically arranged conduction cooling column；Adsorbent is set to described Bottom in tank body, adsorbent upper surface set the jack that several conduction cooling columns for the grillage are planted.

Preferably, the material of the adsorbent is melamine sponge or aeroge.

Preferably, the material of the thermal insulator is PIR, PUR, EPP, EPS or aeroge.

The utility model tank base is filled with suitable liquid nitrogen, and adsorbent absorption liquid nitrogen keeps tank base to be in for a long time Profound hypothermia environment；Adsorbent is inserted into the grillage lower end, the cold air of lower section liquid nitrogen is entered grillage for conduction cooling, thus preferably Keep the activity of biological sample.

When handle swing to upright position, so that hook portion catches on hook ring, the function of lifting tank body is realized, when by handle When being rotated by 90 ° to horizontal position and being located in arc groove, being hidden in lid for handle is realized, and realize lid and tube body Unlock, can be detached from tank body for lid at this time.

The technical effect of the utility model:

The effect of cold insulation is more preferable in the transport of the utility model biological sample, and upper handle of uncapping has hidden function, to use Person's operation is more convenient simple, reduces the probability of biological sample damage.
