Description

Technical Field

[0001] The utility model relates to the technical field of biological instruments, in particular to a bacterial culture dish with a fluorescent scale. The culture dish has the function of directly measuring the size of the inhibition zone and is particularly suitable for microbiology laboratories and medical testing institutions. Background Art

[0002] In traditional bacterial culture, the Kirby-Bauer (KB) disc diffusion method is often used to determine the inhibitory effect of antimicrobial drugs on bacteria. This method involves placing a drug-containing disc on an agar plate coated with bacteria. After a period of incubation, a zone of inhibition forms around the disc. Currently, measuring the size of the zone of inhibition typically requires the use of a ruler or other measuring tool, a method that is not only cumbersome but also prone to errors. Utility Model Content

[0003] The utility model aims to provide a bacterial culture dish with a fluorescent scale, which can solve the problem in the prior art that the bacterial culture dish cannot directly measure the size of the inhibition zone.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A bacterial culture dish with a fluorescent scale comprises a culture dish body. Six scale lines are arranged on the bottom of the culture dish body, namely three horizontal scale lines and three vertical scale lines. The horizontal scale lines and the vertical scale lines are perpendicular to each other. The minimum scale of each scale line is 1 mm, and each scale line is provided with multiple scale marks. The three horizontal scale lines and the three vertical scale lines respectively divide the diameters of two mutually perpendicular culture dishes into four segments of equal length. The scale lines are made of fluorescent material.

[0006] Preferably, the culture dish body is made of transparent or translucent plastic material.

[0007] Preferably, the size of the culture dish body is 90 mm*90 mm.

[0008] Preferably, the scale lines are directly produced on the bottom of the culture dish body by high-precision printing or engraving technology.

[0009] Preferably, the interval between two adjacent scale marks is 5 mm or 10 mm.

[0011] ①Measure the size of the inhibition zone directly on the culture dish without the need for additional measuring tools, simplifying the operation process;

[0012] ②The blue fluorescent scale line is clearly visible, which improves the accuracy and convenience of measurement;

[0013] ③The design of the culture dish makes the measurement process unaffected by ambient light, thus improving the stability of the measurement;

[0014] ④It is suitable for measuring inhibition zones of various sizes and has good versatility and practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example 1

[0021] like Figure 1 As shown, a bacterial culture dish with a fluorescent scale includes a culture dish body 1. The bottom of the culture dish body is provided with six scale lines 2, namely three horizontal scale lines 21 and three vertical scale lines 22. The horizontal scale lines 21 and the vertical scale lines 22 are perpendicular to each other. The minimum scale of each scale line 2 is 1mm, ensuring the accuracy and convenience of measurement. Each scale line 2 is provided with multiple scale markings 23. If the minimum scale is less than 1mm, it is not convenient for naked eye observation. Therefore, the minimum scale of each scale line 2 is not less than 1mm, and can also be set to 2mm or 5mm.

[0022] The three horizontal scale lines 21 and the three vertical scale lines 22 divide the two mutually perpendicular culture dish diameters (L1, L2) into four segments of equal length; the scale lines 2 are made of fluorescent material.

[0023] The scale lines 2 at the bottom of the culture dish body 1 are reasonably arranged and can cover the effective culture area of the entire culture dish to meet the measurement requirements of inhibition zones of different sizes.

[0024] The culture dish body 1 is made of polystyrene material, which has good transparency and chemical stability, and the bottom is flat, which is convenient for observing bacterial growth;

[0025] The scale line 2 is made of a special fluorescent material that emits blue fluorescence under normal lighting conditions, and the fluorescence intensity is sufficient to be clearly visible in a non-ultraviolet light environment;

[0026] Furthermore, the culture dish body 1 is made of a transparent or translucent plastic material to ensure the visibility of the scale lines.

[0027] Furthermore, the size of the culture dish body 1 is 90mm*90mm, which is suitable for agar plates of standard size. The size of the culture dish body 1 can be re-made according to the actual experiment, in order to facilitate observation and various measurements during the experiment.

[0028] Furthermore, the scale lines 2 are directly made on the bottom of the culture dish body 1 by high-precision printing or engraving technology, ensuring the accuracy and durability of the scale lines.

[0029] Furthermore, the interval between two adjacent scale marks 23 is 5 mm or 10 mm, and a smaller interval is helpful for clearly visually observing the minimum scale value.

[0030] The utility model realizes the function of directly measuring the size of the inhibition zone on the culture dish body 1 by arranging a scale line 2 made of fluorescent material at the bottom of the culture dish body 1, thereby improving the efficiency and accuracy of measurement and having good practical value and promotion prospects.
