[0002] Well plates are common laboratory consumables, especially 96-well plates, which are widely used in cell culture, nucleic acid extraction and quantification, enzyme-linked immunosorbent assay (ELISA), immunofluorescence assay, and mass spectrometry. Although 96-well plates can be used with automated equipment such as pipettes and ELISA readers to automate sample addition and detection, the relatively high price of such equipment makes them costly for projects with limited budgets or small-scale research projects, thus limiting their widespread use.
[0003] In practical applications of 96-well plates, most laboratories still use manual direct sample addition. Especially when multiple wells already contain liquid, adding more liquid inevitably leads to the possibility of omissions or incorrect additions, affecting the accuracy of the test results, thus impacting the experimental progress and increasing experimental costs.
[0004] Therefore, there is an urgent need to develop a well plate holder with marking function, which can reduce the probability of missed or incorrect sample addition when adding samples to a 96-well plate. Utility Model Content

[0031] This utility model provides an orifice plate support with marking function. A movable indicator rod is set on the frame to mark the orifice positions that need to be filled with liquid, so as to avoid operators missing or adding liquid in the wrong place and reduce the probability of misoperation. In addition, the tilt angle of the frame can be adjusted by the support to make it easier for the operator to see the liquid filling status in the orifice plate.
[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0033] Example
[0034] Please refer to the reference. Figures 1 to 3 This embodiment provides a perforated plate support with marking function, including a frame 1 and an indicator rod 2;
[0035] The frame 1 has several holes for mounting the perforated plate, and each of its two adjacent sides has a sliding groove 3; each sliding groove 3 has a slider 4.
[0036] Indicator rod 2 is mounted on slider 4. The two indicator rods 2 are used to mark the positions of the holes that need to be filled with liquid.
[0037] Specifically, frame 1 can be made of plastic and is a square plate with square grooves inside. The grooves can be 13cm long and 9cm wide, and the frame 1 is 2.5cm thick. A 96-well plate is installed in the grooves. The pores on frame 1 are large enough to accommodate eight-tube bundles for nucleic acid amplification. Besides holding 96-well plates, it can also be used for eight-tube bundles for nucleic acid amplification in PCR experiments. Target genes extracted in PCR experiments are mostly colorless and transparent, and the sample volume is small. Missed or incorrect additions are often difficult to detect visually. In addition, some samples are not easy to obtain. Using a labeled plate holder can reduce the possibility of errors, avoid wasting valuable samples, and prevent prolonged experimental cycles.
[0038] The holes on frame 1 are formed in square grooves. The holes can be round, and several holes are arranged at even intervals in the horizontal and vertical directions within the grooves. For example, the holes are arranged in eight rows and twelve columns. The holes in the 96-well plate are tubular, and the number and position of the holes on frame 1 correspond to the number of holes on the 96-well plate.
[0039] Two grooves 3 are perpendicular to each other and are respectively opened on the adjacent sides of the frame 1. The grooves 3 can be square grooves. The slider 4 can slide in the groove 3, and the outer side of the slider 4 extends out of the groove 3. The indicator rod 2 is installed on the top surface of the part of the slider 4 that extends out of the groove 3, perpendicular to the top surface of the frame 1. The two indicator rods 2 can mark the specific position on the orifice frame 1. Before the operator adds liquid into the orifice plate, the two indicator rods 2 are moved to the orifice position to be added by the slider 4. After adding liquid, the indicator rods 2 are moved to the next position to be added. After all liquids are added, the two indicator rods 2 are moved back to the starting position, thereby avoiding the operator from missing or adding the wrong liquid and reducing the probability of misoperation.
[0040] In this embodiment, a rotatable elastic buckle 5 is provided on the top side of the frame 1 to fix the perforated plate.
[0041] Specifically, the elastic buckle 5 can be a steel spring clip with a slightly concave front end, which can be used to press the perforated plate. The elastic buckle 5 is installed on the top side of the frame 1 via a rotating shaft. Before installing the perforated plate, the elastic buckle 5 can be rotated outward around the shaft. After the perforated plate is placed into the frame 1, the elastic buckle 5 can be rotated back to press and fix the perforated plate.
[0042] The number of elastic clips 5 can be two pairs, with each pair of elastic clips 5 installed on opposite sides of the top of the frame 1, thereby more stably fixing the perforated plate.
[0043] In this embodiment, the indicator rod 2 is a telescopic rod.
[0044] In practical applications, different models of perforated plates have different thicknesses. When the perforated plate is thicker, it will block the indicator rod 2 on the side of the frame 1. The indicator rod 2 is a telescopic rod, which can be extended to make it easier for the operator to observe the position of the indicator rod 2.
[0045] In this embodiment, a pin hole is provided on the side of the slider 4 facing the slide groove 3, and a spring top pin 6 is embedded in the pin hole. The spring top pin 6 is used to press the slider 4 tightly.
[0046] In practical applications, the spring pin 6 is an existing technology product with a rounded end. The spring pin 6 is embedded in the pin hole, and the head of the spring pin 6 can protrude from the pin hole. When the operator moves the slider 4 to the set position and releases the slider 4, the head of the spring pin 6 will abut against the bottom surface of the slide groove 3, preventing the slider 4 from easily sliding away on the slide groove 3 and improving the positioning accuracy of the slider 4.
[0047] In this embodiment, supports are provided on the bottom sides of the frame 1.
[0048] Specifically, the support includes a base 7, a fixed rod 8, and a telescopic rod 9. The fixed rod 8 is fixedly connected to the base 7, and the fixed rod 7 is rotatably connected to the bottom of the frame 1. The bottom and top ends of the telescopic rod 9 are rotatably connected to the base 7 and the bottom of the frame 1, respectively. The base 7 can be a rectangular long rod, and the fixed rod 8 is vertically fixedly installed on the base 7. The fixed rod 8 can be rotatably connected to the bottom of the frame 1 via hinges, and the top and bottom ends of the telescopic rod 9 can also be rotatably connected to the base 7 and the bottom of the frame 1 via hinges. The telescopic rod 9 can be a product of existing technology. By adjusting the length of the telescopic rod 9, the tilt angle of the frame 1 can be adjusted, making it easier for the operator to observe whether there is liquid in the orifice, and making it easier for the operator to observe the liquid addition status in the orifice during liquid addition.
[0049] In this embodiment, the top adjacent side surface of the frame 1 is engraved with a number to identify the hole number.
[0050] Specifically, the labels can be engraved on the side with indicator rod 2. For example, the rows can be in English letters and the columns can be in Arabic numerals. When recording is required, if there is no number on the well plate, this label can be used to record the test tubes for which liquid was added.
[0051] In this embodiment, the well plate holder with marking function is used by adjusting the tilt angle of the holder, placing the 96-well plate into the groove, and securing the well plate with the elastic clip 5. When adding samples, the two indicator rods 2 can be adjusted to the row and column corresponding to the well position for positioning. The operator then adds the liquid, repeating the above steps to complete the addition of liquid to the next well. This well plate holder with marking function is particularly suitable for wells where liquid is already present. By moving the indicator rods 2, the well positions requiring liquid addition are marked, preventing operators from missing or adding the wrong sample, and reducing the probability of misoperation.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
