Description

Combined Biology Bench

technical field

The invention relates to the technical field of biological experiment equipment, in particular to a combined biological experiment platform.

Background technique

At present, in microbial experiments, it is often necessary to use petri dishes. The petri dishes are made of plastic or glass. Because the glass material is transparent, it is conducive to observation. It has a certain amount, strong operability, and easy to clean. It can be recycled, and the general laboratory still uses glass petri dishes more often. In the laboratory, after cleaning the glass petri dishes, they are often piled up directly or turned upside down on the workbench, and dried naturally, which not only takes up space, but also pollutes work surface, and it is easy to cause water accumulation in the culture dish, which is not conducive to the use of the culture dish;

When using the cleaned and sterilized Petri dishes for the isolation and purification of microorganisms and the tissue culture of animals and plants, it is also necessary to operate on a professional sterile ultra-clean workbench. Due to the small space of the existing ultra-clean workbench, during the operation of inverting the culture dish, it is necessary to stack the culture dishes with the medium poured, otherwise it will not be possible to complete the production of many culture dishes and flat plates, and it will take up the ultra-clean work There is a lot of space on the table, which makes it impossible for other personnel to use it. In addition, during the process of pouring the plate, the experimenter needs to open the culture dish with one hand and get close to the flame of the alcohol lamp, and pour the medium with the other hand. It is difficult to grasp the pouring of the medium during the operation. In the process of pouring the culture medium, the petri dish is not firmly grasped and is easy to drop. Together with the poured part of the culture medium, it spills on the test bench, pollutes the test bench, troublesome cleaning, and delays the progress of the experiment. Moreover, the alcohol lamp is placed directly on the work surface, and it is easy to be touched by the experimenter during the experimental operation, which poses a safety hazard.
