Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to an ELISA plate sample adding and drying device. Background Art

[0002] In the enzyme-linked immunosorbent assay (ELISA), the purity, concentration and ratio of the antigens, antibodies, labeled antibodies or antigens involved in the immunological reaction; the type, concentration and ionic strength of the buffer, pH value, reaction temperature, time and other conditions play a key role. Currently, after using a plate washer to clean the ELISA plate in the laboratory, it is still necessary to pat it dry with disposable paper.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent No.: CN220624606U discloses an ELISA plate drying device, comprising a base, an outer wall of the base is provided with a drying mechanism, a rotating motor is fixedly connected inside the base and on both sides of the drying mechanism, an electronic button is installed on the front of the base, and a power plug is installed on the front of the base and on the right side of the electronic button; the drying mechanism comprises a rotating shaft rotatably connected to the center of the outer wall of the base, the outer wall of the rotating shaft and a mounting seat fixedly connected outside the base, a splint is slidably connected inside the mounting seat, and a connecting rod is rotatably connected to the outer wall of the splint. By designing an ELISA plate drying device, the drying mechanism in the device is used to dry the ELISA plate, which solves the problem that after the ELISA plate is cleaned with a plate washer in the laboratory, disposable paper still needs to be used to pat it dry, which is time-consuming and labor-intensive, and has low work efficiency.

[0005] However, the above patent still has some problems in actual use. The most obvious one is that when centrifugal force is used to separate and dry the water droplets remaining on the ELISA plate, the water droplets remaining on the ELISA plate will splash around under the action of centrifugal force. The splashed water droplets fall on the ground around the operation, which can easily cause ground pollution and slippery problems.

[0006] Therefore, we proposed an ELISA plate sample loading and drying device to solve the above-mentioned drawbacks. Utility Model Content

It is convenient to spin-dry multiple ELISA plates at one time, which greatly improves the drying efficiency of the ELISA plates. Then, the driving motor 410 drives the ELISA plates fixed at multiple fixed positions on the rotating drum 3 to rotate. The water droplets remaining on the rotating ELISA plates will fall off under the action of centrifugal force. The design of the waterproof shell 2 can block the water thrown out during the rotation and drying of the ELISA plates to prevent water from splashing everywhere and water droplets from falling on the ground around the operation to cause ground pollution and slippery problems. At the same time, the collected water can enter the drainage hole 6 through the water collecting plate 5, and finally flow into the collection box 8 for collection and cleaning. It is highly practical and worthy of promotion.

[0041] It should be noted that the model and specifications of the drive motor 410 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in the field, so it will not be described in detail.

[0042] The power supply and principle of the driving motor 410 are clear to those skilled in the art and will not be described in detail here.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
