Description

Technical Field

[0001] The utility model relates to the technical field of microbial detection, in particular to a flat-plate bacterial colony counter. Background Art

[0002] In the field of microbiology research and quality control, plate bacterial colony counting is a basic and crucial experimental technique. It is widely used in food safety, pharmaceutical production, environmental monitoring, scientific research and teaching, etc. It is used to assess the degree of microbial contamination in samples and ensure product safety and quality.

[0003] However, in the process of counting bacterial colonies on a plate, manual observation is usually required for counting operations. Since the bacterial colonies are scattered in the container, counting confusion is likely to occur during the process of naked eye observation, resulting in the need to re-count the operation, which brings more trouble to the bacterial colony counting operation. Therefore, the applicant proposes a flat plate bacterial colony counter to solve the above problem. Utility Model Content

Similar or identical parts are denoted by the same reference numerals in the drawings and descriptions. In actual applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in the present invention are intended only to illustrate the present invention and are not intended to limit its scope. Any obvious modifications or variations to the present invention do not depart from the spirit and scope of the present invention.

[0023] See also Figure 1-5 As shown, the present invention proposes a flat-plate bacterial colony counter, comprising a base mechanism 2 and a counting mechanism 3 assembled on the base mechanism 2, and an observation mechanism 1 assembled on one side of the base mechanism 2. The base mechanism 2 comprises a base 201, an interior of the base 201 is provided with a mounting groove 205, an interior of the mounting groove 205 is fixedly provided with a placement rack 208, the counting mechanism 3 comprises a movable rack 305 hingedly mounted on the other side of the base 201, a fixed frame 301 is fixedly mounted on one end of the movable rack 305, a glass plate 302 is fixedly mounted on the inner side of the fixed frame 301, a surface of the glass plate 302 is engraved with a dividing line 306, a transparent sticker 304 is adhered to the top of the glass plate 302, and a plurality of recording plates 303 distributed in a circular array are fixedly mounted on the top of the fixed frame 301.

[0024] Based on the above-mentioned structural setting, the flat bacterial colony counter is composed of an observation mechanism 1, a base mechanism 2 and a counting mechanism 3, wherein the base mechanism 2 can conveniently store the culture dish containing bacterial colonies, and the counting mechanism 3 can be flipped to cover the top of the bacterial colony culture dish, so that the counting mechanism 3 can conveniently assist personnel in counting bacterial colonies. The observation mechanism 1 can magnify the observation area, so that personnel can conveniently observe the distribution of bacterial colonies with the naked eye, thereby improving the accuracy of counting. Specifically, in the working process, by placing the culture dish containing bacterial colonies into the placement rack 208, the bacterial colony culture dish can be conveniently supported, and the fixed frame 301 can be flipped by the movable rack 305. By flipping the fixed frame 301 to the top of the base 201, the glass plate 302 can be covered on the top of the bacterial colony culture dish. The distribution of bacterial colonies in the culture dish can be conveniently observed through the glass plate 302, and the glass plate 302 can be divided by multiple dividing lines 306. Multiple counting zones are provided so that the bacterial colonies in the culture dish can be displayed in each counting zone. By adhering the transparent sticker 304 to the surface of the glass plate 302, the distribution of the bacterial colonies can be observed without affecting the observation. By using the color marker 203 to dot the surface of the transparent sticker 304 at the position corresponding to the bacterial colony, the bacterial colonies displayed in each counting zone are counted one by one, which can prevent confusion and effectively avoid the trouble of recounting due to confusion. A handle is provided on one side of the transparent sticker 304, which can be easily removed from the glass plate 302 after use and can be replaced, which is convenient for the next counting operation. By having multiple recording plates 303 corresponding to each counting zone, the number of bacterial colonies in each counting zone can be easily recorded to avoid forgetting. By adding the number of bacterial colonies in each counting zone, the total number of bacterial colonies can be quickly obtained, which can effectively improve the accuracy of bacterial colony counting and bring more convenience to counting.

[0025] Furthermore, a lighting strip 207 is fixedly mounted on the inner wall of the mounting groove 205, and a reflector 206 corresponding to the placement rack 208 is fixedly mounted on the bottom of the mounting groove 205. The lighting strip 207 can illuminate the mounting groove 205, and the reflector 206 can reflect light onto the bacterial colony culture dish, making it easy to clearly display the bacterial colonies in the culture dish, allowing personnel to more clearly observe the distribution of the bacterial colonies.

[0026] Furthermore, a calculator 202 is placed on top of the base 201, and a color marker 203 is placed on the top of the base 201 and on one side of the calculator 202. The calculator 202 allows a person to easily add up the number of bacterial colonies recorded on each recording board 303, thereby quickly and easily obtaining the total number of bacterial colonies. The color marker 203 allows the position of the bacterial colonies to be easily marked on the transparent sticker 304, thereby facilitating the counting operation.

[0027] Furthermore, the observation mechanism 1 includes a slide 101 slidably mounted on one side of the base 201, and a slide groove 204 is provided on one side of the base 201 for the slide 101 to slide. The slide 101 can slide along the slide groove 204, so that the position of the observation mechanism 1 can be easily adjusted according to the use requirements.

[0028] Furthermore, a sleeve 102 is fixedly mounted on the top of the slide 101, and a telescopic rod 103 is sleeved on the top of the sleeve 102. The telescopic rod 103 can move up and down along the sleeve 102, so that the height of the observation mechanism 1 can be easily adjusted.

[0029] Furthermore, a magnifying glass 104 is fixedly mounted on one end of the telescopic rod 103, and the magnifying glass 104 corresponds to the counting mechanism 3. The magnifying glass 104 can conveniently magnify and display the bacterial colonies, so that personnel can conveniently observe the distribution of bacterial colonies with the naked eye, thereby improving the accuracy of counting.
