In fields such as biomedical and pharmaceutical applications, various liquids such as a drug solution, a cell suspension, a buffer solution, and a tissue solution are often stored and transported by using a liquid container such as a liquid bag or a liquid bottle. To ensure that the liquid is not contaminated, the container requires a rigorous sterilization process to ensure a sterile environment and is often a disposable consumable. In some high-precision cell suspension processing technologies (such as flow-type electrotransfection), a sample injection container, an electrotransfection device and a sample discharge container are usually connected in a sealing manner through a pipeline to form a set of electrotransfection processing consumables, the sample injection container is used for conveying a cell suspension to be processed to the electrotransfection device, and the sample discharge container is used for receiving the processed cell suspension.

Because the whole set of electrotransfection treatment consumable has larger volume, more pipelines and interfaces, the pipetting operation (sample injection/sample discharge operation) becomes difficult in a sterile environment, and the labor consumption and the working efficiency are low, and the risk of pollution of the cell suspension is increased due to long-time handholding.

The hanging part 3 fixedly connected with the vertical plate 2 can be used for supporting a heavier or larger container (such as a sample injection container 803 or a sample discharge container 804 in electrotransfection treatment consumables), and has higher stability; the hanging portion 3 detachably connected to the vertical plate 2 can be used for supporting a single container (for example, a syringe or a centrifuge tube, which can be used as the sample transfer container 801 or the collection container 802) of a smaller size, so that the positional relationship between the single container and the sample transfer container or the sample discharge container in the electrotransfection treatment consumable can be adjusted at the time of the pipetting operation (sample feeding/discharging operation).

Example 2

As shown in fig. 21-22, this embodiment provides another rack, and the structure, use scenario and use method of the rack are basically the same as those of embodiment 1, and the main difference is that the hanging portion 3 fixedly connected to the vertical plate 2 in this embodiment only includes the first hanging portion 31 and the second hanging portion 32.

When the hook 4 is connected with the vertical plate 2, at least part of the vertical plate 2 is located between the first hanging wall 41 and the second hanging wall 42, the third hanging wall 43 is located in the fixing hole 201 and abuts against the vertical plate 2 at the position corresponding to the bottom of the fixing hole 201, and the first hanging wall 41 is attached to the vertical plate 2, so that the hanging part 3 is stably connected with the vertical plate 2, and shaking is reduced.

Of course, the rack can also be used for two detachable hanging parts 3. As shown in fig. 23, for example, the vertical plate 2 containing ferromagnetic substances is provided with a fixing hole 201, the connection section 301 includes a magnetic attraction portion 7, and the section of the fixing hole 201 is smaller than the section of the magnetic attraction portion 7, so that when the projection of the connection section 301 coincides with the projection of the fixing hole 201, the connection section 301 can be connected with the vertical plate 2 due to the magnetic force as well.

Example 4

As shown in fig. 24-25, this embodiment provides another rack, which is basically the same as embodiment 1, and the main difference is that the top and/or side of the vertical plate 2 of the rack in this embodiment is further provided with a groove 23 for hooking articles, where the groove 23 on the top is opened upwards, and the groove 23 on the side is opened upwards obliquely, so as to facilitate hooking of a smaller component such as a catheter, and further improve the practicality of the rack.

In summary, according to the rack provided by the utility model, the liquid outlet container and the liquid inlet container can be detachably supported on the rack through the liquid outlet support or the liquid inlet support, so that corresponding pipetting operations (sample injection/sample discharge operations) can be conveniently completed, labor can be saved, working efficiency is improved, long-time holding is not needed, and the risk of pollution of cell suspension is greatly reduced.

The above embodiments are provided to illustrate the technical concept and features of the present utility model and are intended to enable those skilled in the art to understand the content of the present utility model and implement the same, and are not intended to limit the scope of the present utility model. All equivalent changes or modifications made in accordance with the spirit of the present utility model should be construed to be included in the scope of the present utility model.
