Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological experimental device technology, specifically to a multi-well culture plate sample labeling device. Background Technology
[0002] 96-well plates are a common consumable in biological experiments, mainly used for quantitative PCR, MTT assays, cell culture, and other experiments. The small spacing and dense distribution of wells in 96-well plates, along with the lack of clear markings between adjacent wells, pose significant challenges, especially in cell biology or molecular biology experiments. Adding small amounts of colorless, transparent liquid samples to the 96-well plate requires intense concentration. Operators typically add samples row by row or column by column. During this process, external interference or operator fatigue can lead to missed or repeated additions, affecting the accuracy of the experiment and potentially causing its interruption or failure.
[0003] For example, Chinese patent application number 202121181316.7 discloses a sample labeling device for a microporous culture plate, including a microporous culture plate, a fixing frame, a base, a lamp plate, an LED control circuit board, and a control switch. The base is a box-shaped structure with an open top. The lamp plate is horizontally set in the base, and multiple light guides are vertically arranged on the lamp plate. The microporous culture plate is set in the fixing frame, which is set in the base, and the culture tubes on the microporous culture plate are respectively located in the light guides. The lamp plate is equipped with multiple LEDs, which are located at the lower end of each light guide. The LEDs are connected to the LED control circuit board, which is connected to the control switch. Operating the control switch can make the multiple LEDs light up one by one in sequence. The light from the LEDs is used as an indicator for the addition of liquid samples, avoiding unexpected interference during the addition of medicine that may lead to repeated additions or omissions, thus ensuring the accuracy of the experiment.
[0004] Those skilled in the art have found that existing technologies are complex in structure, high in cost, and inconvenient to use in practice. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a multi-well culture plate sample labeling device that is simple in structure, easy to use, and inexpensive, so as to facilitate the testing personnel to quickly locate the sample wells of the culture plate and overcome the problems of missed or repeated additions.
[0006] To achieve the above objectives, this utility model provides a multi-well culture plate sample labeling device, including a base plate, a limiting structure, and a labeling part. The base plate includes a transparent plate with the same area as the culture plate. The limiting structure is provided on the edge of the transparent plate. The limiting structure is used to fix the position between the culture plate and the base plate so that it does not shift. The labeling part includes a number of label symbols disposed on the transparent plate and corresponding one-to-one with the positions of the wells in the culture plate.
[0007] Furthermore, the identifier is located at the bottom of the transparent plate and is recessed into the transparent plate by etching.
[0008] Preferably, the identification symbols are points set in a one-to-one correspondence with the well positions of the culture plate.
[0009] Preferably, the identification symbols are numbers or letters set according to the one-to-one correspondence of the well positions on the culture plate.
[0010] Furthermore, the limiting structure includes limiting edge strips disposed on the four sides of the transparent plate and extending upward for a certain distance.
[0011] Furthermore, the limiting edge strip is an edge strip with a length less than the side length of the transparent plate, or several short edge strips.
[0012] Furthermore, the limiting structure includes several guide posts disposed on the four sides of the transparent plate and extending upward for a certain distance.
[0013] Furthermore, the identifier is colored with black or fluorescent dye.
[0014] The beneficial effects of this utility model are as follows:
[0015] The transparent plate is used in conjunction with the culture plate with a limiting structure to ensure that the position between the transparent plate and the culture plate is fixed and will not shift or misalign.
[0016] By setting identification symbols at the bottom of the transparent plate that correspond one-to-one with the well positions of the culture plate, the testing personnel can quickly determine the well positions of the culture plate by means of the identification symbols. At the same time, when the testing personnel add sample liquid into the well positions of the culture plate, the sample liquid will form a convex lens shape in the well positions of the culture plate, thereby magnifying the identification symbols located below the well positions of the culture plate. By observing whether the identification symbols are magnified, the status of sample liquid added into the well positions of the culture plate can be determined.
[0017] The transparent plate has a simple structure and low cost. Since the process of use only requires placing the culture plate on the multi-well culture plate sample labeling device of this utility model, the method of use is simple and quick. Attached Figure Description

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.
[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.
[0025] In this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature. The terms "vertical," "horizontal," "left," "right," "above," "below," and similar expressions are for illustrative purposes only and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting the invention.
[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example 1
[0027] like Figures 1 to 3 As shown, a multi-well culture plate sample labeling device includes a base plate 1, a limiting structure 2, and a labeling part 3. The base plate 1 includes a transparent plate with the same area as the culture plate. The limiting structure 2 is provided on the edge of the transparent plate. The limiting structure 2 is used to fix the position between the culture plate and the base plate 1 so that it does not shift. The labeling part 3 includes a number of label symbols disposed on the transparent plate and corresponding one-to-one with the positions of the wells in the culture plate.
[0028] After the sample solution is added to the well of the culture plate, the sample solution will form a convex lens shape in the well of the culture plate, thereby magnifying the identification mark on the bottom plate 1 located below the well of the culture plate. By observing whether the identification mark is magnified, it can be determined whether the sample solution has been added to the well of the culture plate. If the identification mark is magnified, it means that the well has been added to the well. If the identification mark is not magnified, it means that the well has not been added to the well.
[0029] The transparent plate is used in conjunction with the culture plate using the limiting structure 2, which ensures that the position between the transparent plate and the culture plate is fixed and will not shift or misalign.
[0030] The identification mark is set at the bottom of the transparent plate and is etched into the transparent plate; this can prevent the identification mark from wearing off and fading due to long-term use, thus affecting the observation effect.
[0031] The identifiers are points set according to the one-to-one correspondence of the well positions on the culture plate.
[0032] The limiting structure 2 includes limiting strips 21 that are disposed on the sides of the transparent plate and extend upward for a certain distance.
[0033] The limiting edge strip 21 is an edge strip with a length less than the side length of the transparent plate, or several short edge strips.
[0034] The identifiers are colored with black or fluorescent dye. Example 2
[0035] like Figure 1 As shown, as another configuration of the limiting structure 2 in Embodiment 1, the limiting structure 2 includes a number of guide posts 22 disposed on the sides of the transparent plate and extending upward for a certain distance.
[0036] The identifiers are numbers or letters that correspond one-to-one with the well positions on the culture plate.
[0037] By setting multiple guide pillars on the four sides of the transparent plate, the base plate and the culture plate are kept fixed and will not shift or misalign.
[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
