Description

Technical Field

[0001] The utility model belongs to the technical field of microbiological laboratory appliances, and particularly relates to a bacterial colony observation device. Background Art

[0002] Colony refers to a group of daughter cells visible to the naked eye with certain morphological and structural characteristics formed by a single or a few microbial cells growing and multiplying to a certain extent on the surface or inside of a suitable solid culture medium, with the mother cell as the center. Observation of colonies mainly involves observing the morphology of the colonies, including the size, shape, edge, gloss, texture, color and transparency of the colonies. Colony morphology is one of the important bases for classification and identification of microorganisms.

[0003] At present, most of the observations of colonies in culture dishes in microbiological laboratories are done with the naked eye, magnifying glass or microscope. This method is relatively simple, but there are many limitations, such as 1. Observation with the naked eye and magnifying glass cannot play a protective role and there is a risk of spreading contamination; 2. The observation magnification is not large, and the colonies after the magnification cannot be observed. For example, some colonies are extremely small or embedded in the culture medium, which is not easy to observe. The edges of some colonies have important distinguishing value and need to be magnified to a certain magnification to be observed; 3. Microscope observation has high cost, cumbersome operation process, and it is not easy to move the culture dish during the observation process; 4. External light is difficult to control during the observation process, especially when ultraviolet light is needed to excite the colonies to produce fluorescence, the ultraviolet light source is not easy to control; 5. Generally, the observation of colonies is carried out in a biological safety cabinet, and the glass barrier of the biological safety cabinet affects the observation line of sight and the observation effect. Therefore, it is necessary to design an observation device for the observation of bacterial colonies in the laboratory. Utility Model Content

[0004] The utility model aims at the above-mentioned deficiencies of the prior art and invents a bacterial colony observation device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A bacterial colony observation device comprises a box body, supporting feet, an observation window, a bracket, an eyepiece, an iron culture dish placement box, a magnet and a functional lamp, wherein the bottom of the box body is provided with supporting feet; the top of the box body is provided with an observation window, and the eyepiece is provided on the observation window through the bracket; the iron culture dish placement box is placed in the box body, and the bottom of the box body is provided with a magnet for controlling the movement of the iron culture dish placement box; the functional lamp is provided on the top surface of the box body.

[0007] The observation device designed in the utility model adopts eyepiece observation, and the culture dish is placed in the box and the culture dish can be moved as needed to facilitate observation of bacterial colonies, while also providing sufficient light support for observation.

[0008] Furthermore, the functional lamps include incandescent lamps, 280nm ultraviolet lamps and 360nm ultraviolet lamps. The incandescent lamps are used to provide illumination for observation, the 280nm ultraviolet lamps are used for disinfection and sterilization inside the box, and the 360nm ultraviolet lamps are used to excite the colonies to produce fluorescence.

[0009] Furthermore, it also includes a side window. The box body is provided with a side window, and the side window is used to add reagents to the culture dish or add or reduce the culture dish during the observation process.

[0010] Furthermore, a plurality of iron culture dish placement boxes are arranged in the box body, so that a plurality of bacterial colonies can be observed at the same time.

[0011] Furthermore, it also includes a hydraulic telescopic rod, and the bottom plate of the box body is a movable bottom plate. The movable bottom plate is movably arranged up and down by the hydraulic telescopic rod. During observation, the distance between the culture dish and the eyepiece diameter can be controlled as needed.

[0012] The advantages of the utility model are as follows: the observation device of the utility model provides a closed environment for observation of bacterial colonies that can be sterilized and disinfected, and can provide sufficient optional lighting, thereby avoiding the contamination of the environment by the bacterial colonies during observation; during the observation process, the culture dish can be moved forward, backward, left, right, up and down as needed to achieve the best observation angle; the observation device is clearer than observation with the naked eye and a magnifying glass, is cheaper to use than observation with a microscope, and is simpler to operate.
