Anti-pollution type bacterial culture device for microbial experiment

Abstract

The invention discloses an anti-pollution type bacterial culture device for a microbial experiment. The culture device comprises a culture box, a culture dish, a rubber tube, a stop base, a stop push rod, a rack bar, a chute, a sliding rail, a gear, a motor, a vacuum pump and a one-way valve, wherein the rubber tube is arranged on the upper part of the culture box and communicated with the interior and exterior of the culture box; the stop base is arranged on one side of the rubber tube; the stop push rod is arranged on the other side of the rubber tube and fixedly connected with one end of the rack bar; the chute is formed in the rack bar and positioned in the sliding rail; the rack bar is connected with the gear; the gear is connected with the motor; and the vacuum pump is connected with the culture box through the one-way valve. Medicines are added into the culture dish in the middle of the rubber tube by an injector, and the rack bar is driven by the motor after addition completion, so that the rubber tube is extruded onto the stop base by the stop push rod so as to be closed. Then, the rubber tube is vacuumized by the vacuum pump, pollution in the culture box is avoided, the operation is convenient, the culture result is kept accurate, and the culture device has high popularization and application value.

Description

technical field [0001] The invention relates to a biological experiment device, in particular to an anti-pollution type bacterial culture device for microbial experiments. Background technique [0002] Bacterial culture is a technique that artificially grows and reproduces bacteria. Bacteria are widely distributed in nature, with a large number and many types. They can benefit human beings or become the cause of disease. Most bacteria can be cultivated artificially, that is, they are inoculated on the culture medium to make them grow and reproduce. The cultured bacteria are used for research, identification and application. Bacterial culture is a complex technique. Prior Art In biological experiments, bacteria are usually cultured in a bacterial incubator, but in the process of adding agents, it is inevitable that they will contact with the air or cause interference with other bacteria, thereby affecting the results of bacterial culture. Therefore, there is room for impro...
