Preparation device of antibacterial organic petri dish

Abstract

The invention discloses a preparation device of an antibacterial organic petri dish. The device comprises a base, wherein an installation groove with an upward opening is arranged in the base. The installation groove is internally provided with a ventilation and degerming mechanism for replacing bacteria-containing air in the petri dish with sterile gas. The ventilation and degerming mechanism comprises the installation groove, a dish bottom is installed on the installation groove, air inlets penetrating left and right are symmetrically arranged on the left and right sides of the dish bottom,telescopic spray heads which can extend into the air inlets are symmetrically arranged on the left and right sides of the outer side of the dish bottom. The device completely replaces bacteria-containing air in the petri dish by sterile gas, and the sterilized petri dish is packaged to achieve an antibacterial effect. In the preparation process, the operation is simple, the reaction of the deviceis sensitive, the noise in the preparation process is small, and the preparation process is quiet and quick. In addition, the petri dish prepared by the device has long storage time and good antibacterial performance, and is also used for distinguishing unused petri dishes from used petri dishes after pasting glue, does not need additional marks or subarea storage, and is convenient and quick to use.

Description

technical field [0001] The invention relates to the field of biological experiments, in particular to an antibacterial organic culture dish preparation device. Background technique [0002] As we all know, a petri dish is an organic experimental vessel used for microorganism or cell culture. Usually, the petri dish needs to be sterilized before the experiment to avoid the influence of external bacteria on the experiment. At the same time, it needs to be cleaned after use. And store it in a fixed location; general laboratories use high-temperature spray guns or disinfectant water to sterilize, and they will directly contact the air with bacteria, and there are more or less bacteria to interfere with the accuracy of the experiment, while the disinfection and sterilization of petri dishes in large laboratories It needs to be carried out in a sterile room, the construction cost of the sterile room is high, and the versatility is poor for ordinary culture experiments; in addition...

[0002] As we all know, a petri dish is an organic experimental vessel used for microorganism or cell culture. Usually, the petri dish needs to be sterilized before the experiment to avoid the influence of external bacteria on the experiment. At the same time, it needs to be cleaned after use. And store it in a fixed location; general laboratories use high-temperature spray guns or disinfectant water to sterilize, and they will directly contact the air with bacteria, and there are more or less bacteria to interfere with the accuracy of the experiment, while the disinfection and sterilization of petri dishes in large laboratories It needs to be carried out in a sterile room, the construction cost of the sterile room is high, and the versatility is poor for ordinary culture experiments; in addition, because biological experiments often use the method of combined experiments for experiments, the number of petri dishes is large, and the ordinary culture after sterilization Petri dishes need to be marked manually to distinguish non-sterilized petri dishes. The process is cumbersome, and experimenters are easy to misuse non-sterilized petri dishes for experiments; it is necessary to design an antibacterial organic petri dish preparation device to solve the above problems
