Description

Technical Field

[0001] This utility model relates to the field of biological consumables technology, specifically to a novel sample dispensing tank. Background Technology

[0002] In cell biology and molecular biology experiments, it is often necessary to use multichannel pipettes (multichannel pipettes) to add liquid reagents. This involves using a multichannel pipette to draw liquid reagents stored in the loading tray and add them to the required location. This process usually requires the cooperation of both the multichannel pipette and the loading tray, which is a tool used to transfer liquid reagents.

[0003] However, existing sample loading trays still have some drawbacks, and some practical functions need improvement. For example, the bottom structure of existing sample loading trays is generally a flat surface, making the bottom relatively smooth. When operators use multichannel pipettes to aspirate liquid reagents from inside the sample loading tray, the contact between the multichannel pipette and the sample loading tray causes the tray to be under stress. Combined with the smooth bottom of the tray, the sample loading tray may shift on the platform, thus hindering the liquid aspiration work of the multichannel pipette and greatly reducing the aspiration efficiency of the process. In addition, most existing sample loading trays do not have a corresponding label placement structure. Most operators simply stick the labels directly to the outer shell of the sample loading tray. Because these adhesive labels have a certain degree of stickiness, it often takes a lot of time and effort for operators to remove the labels, which is very inconvenient. Utility Model Content

[0004] To address the problems mentioned above, the present invention aims to provide a novel sample dispensing tank. This tank features several inclined columns with a frosted layer at its bottom to prevent displacement during liquid aspiration by a multi-channel pipette. Furthermore, a label placement slot on the top cover replaces the traditional method of directly attaching labels to the surface of the sample dispensing tank.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel sample dispensing slot includes a top cover and a main box body. The top cover is disposed on top of the main box body. The bottom of the main box body is provided with a first groove. Several inclined columns are disposed inside the first groove. The bottom of each of the several inclined columns is provided with a frosted layer. The top of the top cover is provided with a label placement slot. A label placement opening is provided on one side of the label placement slot.

[0007] Furthermore, a second groove is provided inside the main box, a storage cavity is formed in the cavity above the second groove, a liquid accumulation tank is provided at the bottom of the second groove, and the storage cavity stores the externally provided sampling liquid.

[0008] Furthermore, the inclined column is injection molded to form an integral part with the bottom of the main box, and the frosted layer is fixedly adhered to the bottom of the inclined column.

[0009] Furthermore, the second groove is configured as an L-shaped groove, and the liquid accumulation groove is configured as a V-shaped groove.

[0010] Furthermore, an externally positioned label is placed inside the label placement slot.

[0011] Furthermore, a rim is provided at the bottom edge of the main box body.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) The bottom of the sample tank of this utility model is provided with several inclined columns with a frosted layer to increase the friction between the sample tank and the platform it contacts, so as to prevent the multi-channel pipette from displacing on the platform due to the force on the sample tank and the smooth bottom when it draws liquid from the sample tank. This effectively ensures that the multi-channel pipette can draw liquid from the sample tank smoothly and ensures the liquid drawing efficiency of the multi-channel pipette.

[0014] (2) The top of the cover of this utility model is provided with a label placement slot, and a label placement opening is provided on one side of the label placement slot. The staff can place non-adhesive labels into the label placement slot through the label placement opening, thereby replacing the traditional method of directly pasting labels on the outer surface of the sample tank. This eliminates the need for staff to spend extra time and effort to remove adhesive labels, achieving the effect of saving time and effort. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-3 As shown, a novel sample loading slot is provided in this embodiment of the utility model. The sample loading slot includes an upper cover 1 and a main box 2. The upper cover 1 is closed and disposed above the main box 2. A first groove 3 is provided at the bottom of the main box 2. Several inclined columns 301 are provided inside the first groove 3. The bottom of the several inclined columns 301 is provided with a frosted layer 4. A label placement slot 5 is provided at the top of the upper cover 1. A label placement opening 501 is provided on one side of the label placement slot 5.

[0021] Specifically, the top cover 1 and the main box 2 are both made of polypropylene material. Polypropylene material has the advantage of strong resistance to chemical corrosion and is suitable for storing most polar organic solutions, acidic or alkaline solutions.

[0022] Specifically, the frosted layer 4 is composed of abrasive material.

[0023] The main body 2 of this utility model has a second groove 6 inside, and a storage cavity 7 is formed in the cavity above the second groove 6. A liquid accumulation tank 601 is provided at the bottom of the second groove 6, and the storage cavity 7 stores the externally provided sampling liquid.

[0024] Specifically, the collection tank 601 can collect the remaining sampling liquid inside the storage chamber 7, so that the multi-channel pipette can extract the sampling liquid stored in the storage chamber 7 to the maximum extent.

[0025] The inclined column 301 of this utility model is injection molded and integrated with the bottom of the main box 2, and the frosted layer 4 is fixedly attached to the bottom of the inclined column 301.

[0026] Specifically, the frosted layer 4 increases the friction between the bottom of the main box 2 and the platform it contacts, so that the sample tray can be stably placed on the platform when the sample liquid is drawn up by the multi-channel pipette.

[0027] The second groove 6 of this utility model is configured as an L-shaped groove, and the liquid accumulation groove 601 is configured as a V-shaped groove.

[0028] Specifically, the V-shaped liquid collection groove 601 is adapted to the position of the tip of the externally installed multi-channel pipette.

[0029] The label placement slot 5 of this utility model contains an externally set label.

[0030] Specifically, the externally mounted label is a non-adhesive label, and the overall size of the non-adhesive label is smaller than the overall size of the label placement slot 5, so that the staff can easily place the non-adhesive label into the label placement slot 5 from the label placement opening 501.

[0031] The bottom edge of the main box 2 of this utility model is provided with a rim 8.

[0032] Reference Appendix Figure 1-3 The process of using this novel sample addition tank is as follows:

[0033] When it is necessary to label the sample liquid stored inside the sample tank, the staff will label the name of the sample liquid on a non-adhesive label, and then place the non-adhesive label into the label placement slot 5 through the label placement port 501.

[0034] When it is necessary to extract the sample solution stored in the sample loading tank using a multichannel pipette, first open the top cover 1, insert the pipette tip of the multichannel pipette into the storage chamber 7 to extract the sample solution. After extracting the sample solution in the storage chamber 7 for a period of time, the remaining sample solution will collect in the accumulation tank 601. At this time, the pipette tip of the multichannel pipette can be inserted into the accumulation tank 601 to extract the remaining sample solution, thereby maximizing the extraction of the sample solution stored in the sample loading tank.

[0035] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
