Description

Technical Field

[0001] The utility model relates to the technical field of laboratory equipment, in particular to a recovery device for containing waste liquid pipette tips. Background Art

[0002] In the fields of biotechnology, pharmaceuticals, chemistry, chemical engineering, etc., the separation of pipette tips and waste liquid is a routine operation in laboratories, analytical testing rooms or workshops. Operators often use single-channel or multi-channel pipettes to aspirate the reacted solution, and this solution needs to be dispensed into a special waste liquid container, and then the pipette tips are dispensed into another waste container. This operation requires the preparation of two containers and an operation of draining the liquid, so there are deficiencies of cumbersome, laborious and time-consuming operations. Or, the operator can dispense the pipette tips together with the waste liquid into one container, but after the operation, the pipette tips still need to be separated from the waste liquid, so there is also the problem of time-consuming and laborious. It can be seen that under the conditions of existing laboratory equipment, both treatment methods have drawbacks and waste time and manpower during or after the operation.

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0023] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model; the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] Referring to Figures 1-3 , an embodiment provided by the present utility model: A recycling device for containing waste liquid suction heads includes a collection cup 1. The collection cup 1 is cylindrical and has an open top. One side of the outer surface of the collection cup 1 is fixedly connected with a handle 2. On one side of the top of the collection cup 1 away from the handle 2, there is a liquid pouring port 3. The liquid pouring port 3 is in an inclined opening form, which is convenient for pouring liquid. A filter 4 is nested inside the collection cup 1. The filter 4 is also cylindrical and has an open top. The outer diameter of its main body is slightly smaller than the inner diameter of the collection cup 1, so that it can be conveniently placed inside the collection cup 1. At the bottom position of the filter 4, there are liquid passing holes 5. And at the top of the filter 4 and above the collection cup 1, there is an upper edge 6 of the filter. The outer diameter of the upper edge 6 of the filter is larger than the outer diameter of the collection cup 1, so that the filter 4 can be stably carried on the top of the collection cup 1. At the side position of the upper edge 6 of the filter, there is a filter handle 7 fixedly connected. The setting of the filter handle 7 can facilitate the hand-held taking of the filter 4.

[0025] There are multiple liquid passing holes 5 and they are evenly distributed at the bottom position of the filter 4. The aperture of the liquid passing holes 5 is 3 - 5 mm, and the total covered area of the liquid passing holes 5 accounts for 30 - 60% of the bottom area of the filter 4. The aperture of the liquid passing holes 5 can be 5 mm, and the covered area ratio is 60%. In this way, the waste liquid can uniformly and stably enter the collection cup 1 through the liquid passing holes 5.

[0026] The height of the filter 4 is 55 - 65% of the height of the collection cup 1. The height ratio can be 60%. This ratio can ensure that the filter 4 has enough space to accommodate the pipette tips and can also ensure that the collection cup 1 has enough space to hold the waste liquid flowing out automatically.

[0027] The materials of the collection cup 1 and the filter 4 are both polypropylene. Polypropylene has the advantages of low production cost, light weight, resistance to corrosion by acid, alkali, salt solutions and various organic solvents, and can withstand high-pressure steam sterilization.

[0028] Working principle: When using the recycling device for holding waste liquid pipette tips, first use a single-channel or multi-channel pipette to aspirate the reacted solution (i.e., waste liquid), and then insert the pipette tip with waste liquid (such as 20 μL, 200 μL, 300 μL, 1 mL, 5 mL) into the filter 4. Under the action of gravity, the liquid will flow down through the liquid passage hole 5 and enter the collection cup 1. After all the experimental operations are completed, hold the handle 2 and gently shake the device to make the remaining liquid in the pipette tip and on its outer wall flow down through the liquid passage hole 5. Then, grasp the filter handle 7 and pour the pipette tips in the filter 4 into the trash can. Hold the handle 2 and pour out the waste liquid inside the collection cup 1 through the pouring port 3. Through the above simple operations, the separation of waste liquid and solid waste pipette tips can be easily achieved.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
