Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of experimental reagent kits, in particular to a 96-well plate auxiliary operation device. Background Art
[0002] The 96-well plate is a widely used experimental consumable material with a large usage volume. It can be used for biochemical analysis and cell experiments in pharmaceutical research and development, such as polymerase chain reaction. A typical structure of a 96-well plate includes a rectangular well plate body and a sample well integrally formed on the well plate body. The bottom of the sample well is closed, and a container with a certain volume can be formed for sample addition. Among them, 96 blind holes are opened on the plate well body. The 96 blind holes are divided into 12 columns, and each column has 8 blind holes. The distance between two adjacent blind holes in the vertical or horizontal direction is the same.
[0003] However, there are no obvious markings between the wells of the 96-well plate, and several problems will be encountered when adding various reagents: First, when adding samples, you need to concentrate on counting or remembering the positions of the wells you want to add, and you may easily get tired and dizzy during the operation, which may lead to adding samples to the wrong wells and causing sample waste; second, some wells need to be protected from light after adding samples, but experimenters cannot operate in a dark room, so these wells that have been added with reagents have to be exposed to light, and they have to wait until all the wells are processed before they can be covered with lids to avoid light, which may affect the experimental results; third, for some experiments with a small number of samples, experimenters only need to operate certain columns of sample wells, but it is not easy to find which wells have samples. Utility Model Content
[0004] The utility model aims to provide a 96-well plate auxiliary operation device to solve the problems that the existing 96-well plate is easy to add wrong samples and cannot be protected from light in time.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] The basic technical solution provided by the utility model is:
[0007] A 96-well plate auxiliary operation device comprises an end cover covering the 96-well plate, the end cover being provided with a plurality of strip-shaped through holes, and each of the strip-shaped through holes corresponds to a column of sample wells, a first opening communicating with the strip-shaped through holes is provided on one side of the end cover, and a second opening communicating with the strip-shaped through holes is provided on the other side of the end cover; an upper light shielding plate and a lower light shielding plate for covering the strip-shaped through holes are slidably connected to the end cover, and the lower light shielding plate is located directly below the upper light shielding plate.
[0008] Principles of basic technical solutions:
[0009] Each strip-shaped through hole corresponds to a column of sample holes, and the sample holes are exposed, which is convenient for adding samples from the strip holes into the sample holes. A first opening connected to the strip-shaped through hole is provided on one side wall of the end cover, which is convenient for the upper light shielding plate to slide in or out of the end cover. A second opening is provided on the side wall of the end cover opposite to the first opening, which is convenient for the lower light shielding plate to slide in or out of the end cover. The lower light shielding plate is located below the upper light shielding plate, so that the lower light shielding plate can be pulled to expose a sample hole. After adding the sample, the upper light shielding plate can be pushed to cover the sample hole.
[0010] The beneficial effects of the basic technical solution are:
[0011] (1) By setting two layers of shading plates, it is possible to cover one sample hole when adding one sample, so that light can be avoided in time during the experiment, thereby increasing the accuracy of the experimental results; in addition, the shading plate also serves as an indicator. The experimental operator can know which sample hole the sample is added to according to the position of the shading plate, without having to remember the position of a sample hole specifically. It is easy to use and is not easy to add the wrong sample, which reduces the workload of the experimenter and improves the experimental efficiency;
[0012] (2) The sample wells with added samples are all covered by the upper light shielding plate, while the sample wells without added samples are only covered by the lower light shielding plate. For experiments with a small number of samples, the experimenter can easily find a few rows of sample wells to operate based on the light shielding plate;
[0013] (3) The materials used in the device of the utility model are easy to obtain and inexpensive, and the device is simple to manufacture and easy to use.
[0014] Preferably, first sliding grooves adapted to the thickness of the upper light shielding plate are formed on both side walls of the strip-shaped through hole, and the upper light shielding plate is slidably connected in the first sliding grooves.
[0015] Through the above arrangement, the first slide groove is adapted to the thickness of the upper shading plate, and only the slide groove needs to be opened on the end cover, which reduces the process flow, facilitates manufacturing, and is easy to use; and the upper and lower walls of the slide groove can also limit the up and down movement of the shading plate.
[0016] Preferably, the two side walls of the strip-shaped through hole are further provided with second slide grooves adapted to the thickness of the lower shading plate, the second slide grooves are located directly below the first slide grooves, and the lower shading plate is slidably connected in the second slide grooves.
[0017] Through the above-mentioned setting, the second slide groove is adapted to the thickness of the lower light shielding plate, and only the slide groove needs to be opened on the end cover, which reduces the process flow, facilitates manufacturing and is easy to use; and the upper and lower walls of the slide groove can also limit the up and down movement of the lower light shielding plate; and the lower slide groove is located directly below the upper slide groove, which is convenient for processing and manufacturing.
[0018] Preferably, the first slide groove has the same size as the second slide groove; the first opening has the same size as the second opening.
[0019] Through the above arrangement, the first slide groove and the second slide groove have the same size, which is easy to manufacture, and the upper shading plate and the lower shading plate can be used alternately. In case the upper shading plate or the lower shading plate is lost, there can be a replacement; the first opening and the second opening have the same size, and the shading plate can slide into the slide groove from the first opening or the second opening, increasing the convenience of use.
[0020] Preferably, the size of the end cap is larger than that of a 96-well plate.
[0021] Through the above arrangement, the size of the end cap is larger than that of the 96-well plate, so that the end cap can be covered on the 96-well plate to fix the end cap, and the operation is simple.
[0022] Preferably, the number of the strip-shaped through holes is 12.
[0023] Through the above arrangement, there are 12 strip-shaped through holes, that is, the length direction of the strip-shaped through holes extends along the width direction of the 96-well plate. In this way, the length of the light shielding plate is shorter, which is convenient for manufacturing, and the space occupied during the experiment is smaller, saving space.
[0024] Preferably, one end of the shading plate is connected to a handle, and the handle is provided with an anti-slip protrusion.
[0025] Through the above arrangement, a handle is provided to facilitate pushing and pulling of the sunshade, and an anti-skid protrusion is provided on the sunshade to prevent slipping.
[0026] Preferably, the upper end and the side end of the strip-shaped through hole of the end cover are provided with indicator marks for marking the order of the sample holes.
[0027] The above arrangement makes it easy to identify the position of the sample hole.
[0028] Preferably, the upper shading plate and the lower shading plate are both made of polyvinyl chloride.
[0029] Through the above arrangement, polyvinyl chloride is easily available at a low price. BRIEF DESCRIPTION OF THE DRAWINGS
