Description

Technical Field

[0001] The utility model relates to the technical field of cryopreservation tubes, in particular to a cryopreservation tube thawing device. Background Art

[0002] When storing cell culture fluid for a long time, the cell culture fluid needs to be transferred to a cryotube and stored at low temperature using a cryopreservation device. When extracting the cell culture fluid in the cryotube, the cell culture fluid needs to be thawed before extraction. When thawing the cryotube, in order to prevent the cryotube from bursting, the cryotube needs to be placed in warm water at about 37°C for water bath thawing. During the thawing process, the cryotube can be shaken to evenly heat the temperature to improve the thawing efficiency. The above-mentioned cryotube thawing operation process has the following defects: (1) Manually shaking the cryotube increases labor intensity; (2) Only a limited number of cryotubes can be operated at the same time, which is not suitable for large-scale cell recovery; (3) The poor fluidity of warm water during water bath thawing will cause uneven water bath temperature, resulting in uneven thawing effect of the cryotube and poor thawing effect.

[0003] To this end, we propose a cryotube thawing device to achieve the effect of quickly thawing cell culture fluid in cryotubes under water bath heating conditions. Utility Model Content

[0009] Preferably, an inspection door is fixedly installed on the front of the device body.

[0010] Preferably, a controller for controlling the electrical components of the device is fixedly mounted on the device body.

[0011] Beneficial Effects

[0012] The utility model provides a freezing tube thawing device. Compared with the prior art, it has the following beneficial effects:

[0013] 1. A freezing tube thawing device, a rotating shaft is installed at the output end of a motor, supporting frames are distributed on the rotating shaft at equal angles, and rubber sleeves are distributed on the supporting frames at equal intervals for clamping and installing freezing tubes. Multiple rubber sleeves on multiple supporting frames can be used to thaw freezing tubes in batches after installation, and are suitable for large-scale cell recovery.

[0014] 2. In this freezing tube thawing device, a rotating shaft is installed at the output end of the motor. The motor can drive the supporting frame and the rubber sleeve to rotate by driving the rotating shaft to rotate, and then drive the freezing tube to rotate. The motor can be driven up and down by the cylinder to move down to the water bath inside the water bath for heating, so that the automatic rotation of the freezing tube can simulate manual shaking, thereby reducing manpower participation and alleviating labor intensity.

[0015] 3. In this frozen tube thawing device, the water in the water bath is heated by an electric heating plate. During the heating process, the poor fluidity of the water in the water bath will lead to uneven water temperature distribution. The water can be stirred by rotating the supporting frame, so that the temperature of the frozen tube is more evenly distributed, improving the thawing effect. By starting the water pump, the water at the bottom of the water bath can be pumped to the nozzle and sprayed toward the top of the water bath from the nozzle, thereby enhancing the water fluidity inside the water bath, making the water temperature distribution more even, and effectively improving the thawing effect of the frozen tube.
