Description

Technical Field

[0001] The utility model relates to the field of covering films, and particularly to a multi-selection 96-well plate covering film. Background Technique

[0002] A 96-well plate refers to a 96-well sample addition plate. When conducting HLA high-resolution tests, it is necessary to shake the 96-well plate with added reagents at a high speed for 10 minutes to fully mix them. When mixing, the 96-well plate is placed in a microplate rapid oscillator for mixing. This traditional microplate oscillator usually has a plate holder with two holes, four holes, or even six holes, which means that two, four, or six 96-well plates can be shaken simultaneously. However, the tray of this traditional microplate oscillator simply places the 96-well plate flat in the square frame of the tray without a special structure for fixing the 96-well plate. During the shaking process, the 96-well plate is prone to moving and falling off, resulting in the overflow of the liquid inside, not only causing pollution but also being unfavorable for the smooth progress of the experiment. In existing microplate oscillators, the oscillator itself may have a lid, but it cannot prevent the overflow caused by the movement and falling off of the 96-well plate. And during use, the number of covering film plugs cannot be selected according to the actual usage situation. Content of the Utility Model

[0004] A multi-selection 96-well plate covering film provided by the utility model includes: covering film plugs, inner frames, and outer frames. A plurality of inner frames arranged in an array are evenly distributed inside the outer frame. The inner frames intersect horizontally and vertically to form a plurality of frames, and the bottoms of the frames are correspondingly connected to the covering film plugs.

[0005] Preferably, the inner frames are connected in a discontinuous dot pattern.

[0006] Preferably, the shape of the covering film plugs includes a cylindrical shape or a frustum shape.

[0007] Preferably, the cross-section of the covering film plugs is in the shape of a frustum.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] This application uses multiple cover film plugs adapted to a 96-well plate to avoid the volatilization of reagents and cross-contamination between different wells; through the discontinuous dot-connected inner border, it can be flexibly cut, and the number of cover film plugs can be selected according to the actual number of samples. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] By reading the following detailed description of the non-restrictive embodiments with reference to the accompanying drawings, other features, objects, and advantages of the present utility model will become more apparent:

[0016] Figure 1 It is a schematic diagram of the overall structure of the present utility model.

[0017] As shown in the figure: cover film plug 1, inner border 2, outer border 3. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that those of ordinary skill in the art can make several changes and improvements without departing from the concept of the present utility model. These all belong to the protection scope of the present utility model.

[0019] Embodiment

[0020] A multi-selectable 96-well plate cover film provided by the present utility model is applicable to a 96-well plate with a length of 12.8 cm and a width of 8.5 cm, and includes: a cover film plug 1, an inner border 2, and an outer border 3. A plurality of inner borders 2 arranged in an array are evenly distributed inside the outer border 3. The inner border 2 is connected in a discontinuous dot pattern and can be cut according to the actual size of the cover film to be used. The plurality of inner borders 2 intersect horizontally and vertically to form 96 frames, and the frames are square. A cover film plug 1 is correspondingly connected to the bottom of each frame. The shape of the cover film plug 1 includes a cylindrical shape or a frustum shape, and the cross-section of the cover film plug 1 is frustum-shaped. The cover film plug 1 is made of soft rubber material, similar to a wine cork, and is plugged through friction. The cover film plug 1 is adapted to the treatment holes on the 96-well plate to prevent cross-contamination of samples and prevent the volatilization of reagents.

[0021] More specifically, according to the shape of the holes on the 96-well plate (square or circular), the corresponding cover film plug 1 (frustum shape or cylindrical shape) is selected, aligned with the 96 treatment holes, and pressed down. Through the friction between the cover film plug 1 and the treatment holes, the treatment holes can be tightly plugged by the cover film plug 1.

[0022] If it is less than 96 wells, for example, only 12 wells in the same row are used. In this case, we can cut one row of the cover film and cover the corresponding row on the 96-well plate. If 4 wells of the 96-well plate are used, we can also cut 4 cover films of the cover film. According to whether the used wells are in the same row or the same column, select the corresponding cover film. This can avoid waste of the cover film. At the same time, for the wells used in the 96-well plate, there is no need to lift the cover again, which can prevent liquid splashing and contaminating other samples.

[0023] The cover film with discontinuous dot connections, the inner border 2 is similar to the cap of a mineral water bottle. When cutting, scissors can be used, or it can be pulled forcefully by hand. When cutting, it can be cut according to the discontinuous points, and the cut is relatively straight without damaging the adjacent cover film plug 1.
