Description

Technical Field

[0001] The utility model relates to the field of liquid transfer workstations, in particular to a multi-channel liquid transfer workstation. Background Art

[0002] The pipetting workstation is an efficient and reliable experimental tool. Its main function is to move liquids, separate them, and screen drugs in the fields of biochemistry, medicine, and pharmacy. The pipetting workstation can help scientists complete various experiments quickly, accurately, and conveniently.

[0003] The Chinese utility model patent with publication number CN220715907U discloses a multi-channel pipetting workstation, which can extract and transfer multiple liquid samples at the same time through the cooperation of the pipetting component and the liquid collection component without repeating multiple operations, thereby greatly improving the efficiency of the entire pipetting work. However, it lacks the treatment of the liquid collection head after use. Since some experimental liquids are corrosive or toxic, they often need to be disinfected or destroyed after treatment. However, they often need to be transported in the middle to be centrally processed, which is likely to cause cross-harm during the transportation process.

[0004] Therefore, a multi-channel pipetting workstation is provided to solve the above problems. Utility Model Content

[0013] Preferably, in order to facilitate pouring out the liquid collection tube in the storage box, the workstation also includes a flipping mechanism, which includes a hinge fixedly installed on the top of the support plate and the outer wall of the storage box, a slide groove is opened at the bottom of the storage box, and a T-shaped pull rod is slidably installed inside the slide groove, and the T-shaped pull rod consists of a rod part adapted to the slide groove and a handle part fixedly installed at the bottom of the rod part and located below the hollow part of the support plate. After the liquid collection tube in the storage box is disinfected, the T-shaped pull rod is pulled out from under the support plate, and then the T-shaped pull rod is pushed upward, so that the storage box rotates along the hinge to pour out the liquid collection tube for easy collection.

[0014] Preferably, a spring is fixedly installed between one end of the inner wall of the slide groove and the end of the slide groove. The spring is in a tightened state in its natural state. When the T-shaped pull rod is pulled out and released, the spring will automatically contract and pull the rod, so that the handle will automatically contract and reset to the bottom of the support plate. No manual operation is required, and it will not accidentally detach and cause the support plate to flip over. It is safe and reliable.

[0015] (III) Beneficial effects

[0016] This workstation uses a multi-channel pipette to place the liquid collection tube into the storage box, then closes the box cover, and then uses the lifting component to lower the storage box into the liquid storage bin in the processing channel. The disinfectant penetrates into the liquid collection tube in the storage box from the water permeable hole to disinfect it in time. There is no need for intermediate transportation, no risk of cross infection, and it is safer and more reliable.

[0017] In this workstation, after the liquid collection tube in the storage box is disinfected, it is pulled out from under the support plate by pulling the T-shaped pull rod, and then the T-shaped pull rod is pushed upward to make the storage box rotate along the hinge to pour out the liquid collection tube for easy collection.

[0028] When in use, the liquid collection tube 2 is placed in the storage box 43 through the multi-channel pipette 3, and then the box cover 44 is closed. Then, the storage box 43 is lowered to the liquid storage bin 46 in the processing channel 41 through the lifting component. The disinfectant penetrates into the liquid collection tube 2 in the storage box 43 from the water permeable hole 45, and is disinfected in time without the need for intermediate transportation. There is no risk of cross infection, and it is safer and more reliable.

[0029] The lifting component includes a lifting slot 47 provided on the inner wall of the processing channel 41, a screw rod 48 is rotatably installed inside the lifting slot 47, the top end of the screw rod 48 passes through the top of the processing channel 41 and is installed with a motor 49, and a slider 410 fixedly installed with the support plate 42 is screwed on the outer wall of the screw rod 48. When in use, by starting the motor 49, the screw rod 48 rotates, driving the slider 410 to move up and down in the lifting slot 47, thereby driving the storage box 43 on the support plate 42 to be lifted and lowered, so as to bring it into the bottom of the processing channel 41 or the top of the processing channel 41, which is convenient and quick.

[0030] Further, a door 411 is provided near the bottom of the outer wall of the processing channel 41, and the liquid storage bin 46 is plugged into the inner bottom of the processing channel 41 through the door 411. When in use, the liquid storage bin 46 is taken out from the door 411 to facilitate replacement of the disinfectant.

[0031] Furthermore, a heating chamber 412 is provided at the inner bottom of the processing channel 41 below the liquid storage bin 46, and an electric heating tube 413 is fixedly installed inside the heating chamber 412. When in use, the disinfectant or water in the liquid storage bin 46 is heated by the electric heating tube 413, thereby quickly disinfecting the liquid collection tube 2, which is convenient and quick.

[0032] Example 2

[0033] Different from Example 1, Figure 3 and Figure 4 As shown, the workstation also includes a flipping mechanism 5, which includes a hinge 51 fixedly installed on the top of the support plate 42 and the outer wall of the storage box 43. A slide groove 52 is provided at the bottom of the storage box 43. A T-shaped pull rod 53 is slidably installed inside the slide groove 52. The T-shaped pull rod 53 consists of a rod portion 531 adapted to the slide groove 52 and a handle portion 532 fixedly installed at the bottom of the rod portion 531 and located below the hollow part of the support plate 42.
