Laboratory microbiological detection culture device

Abstract

The invention discloses a laboratory microbiological detection and culture device which comprises an extraction box, a centrifugal homogenization unit, a preparation unit, a sample liquid transportation and inoculation unit and a culture unit, wherein the extraction box is used for centrifugally homogenizing sample liquid and preparing sample liquid with different concentration gradients; the preparation unit is used for preparing the sample liquid with different concentrations; sample solutions with different concentrations are automatically prepared in the closed extraction box, so that microorganisms introduced when experimenters manually prepare the sample solutions with different concentrations are avoided, and the accuracy of experimental results is improved; in the preparation process, a new pipette is automatically replaced when the sample liquid with different concentrations is sucked each time, so that the concentration accuracy of the sample liquid is ensured.

Description

technical field [0001] The invention relates to the field of medical detection and experimental equipment, in particular to a laboratory microorganism detection and cultivation device. Background technique [0002] In the steps of testing microorganisms in the laboratory, sampling and centrifugation are generally performed first, and then the centrifuged sample homogeneous solution is re-sampled to produce multiple homogeneous solutions of different concentrations, and then the sample solutions of different concentrations are injected into the plate. Add culture medium to the plate, and carry out constant temperature culture to the microorganisms in the sample solution with different concentrations. After the culture is completed, the targeted detection step is carried out. Today's cultivation process is carried out by experimenters entering the laboratory after disinfection. In the laboratory, each step is manually operated by the experimenter. While the operation steps are...

Problems solved by technology

Today's cultivation process is carried out by experimenters entering the laboratory after disinfection. In the laboratory, each step is manually operated by the experimenter. While the operation steps are time-consuming and laborious, there may be residual bacteria. With the experimenter's The respiration process will also produce new bacteria, which may be mixed with other bacteria during the cultivation process, which will affect the results
