a biological test strip

Abstract

The invention discloses a biological test piece, which comprises a casing, a working chamber is arranged inside the casing, a fixing assembly is arranged on the upper end of the casing, and the fixing assembly includes an inner wall on the upper side of the working chamber and is connected with the outside world. The first through hole communicated with the first through hole is symmetrically arranged on the upper end of the housing with respect to the first through hole and the two linkage sliders can slide left and right, and the semi-rubber half rubber fixed on the end of the linkage slider close to the center of symmetry. Circle, the invention can discharge the planktonic bacteria in the working chamber to the outside in advance by increasing the rotation speed of the fan when the test tube containing the microbial stock solution does not enter the working chamber, thereby reducing the interference to the experiment to the greatest extent, and the device can detect and cultivate For the cultivation of microorganisms in the tank, by moving the movable baffle upwards in time, the microorganisms can be supplemented with water to ensure the cultivation and reproduction of microorganisms, and the whole process is carried out in the working chamber and the water supply chamber, so that the photosensitive microorganisms can also be well To cultivate.

Description

technical field [0001] The invention relates to the field of microorganism culture, in particular to a biological test piece. Background technique [0002] Most of the current biological test strips, after obtaining the microbial stock solution, cannot well guarantee the light-shielding properties of some photosensitive microorganisms, and most of the test strips are easily affected by the residual planktonic bacteria in the air during cultivation. Moreover, some microorganisms are more active and have a greater demand for water. Failure to replenish water in time will easily lead to inaccurate culture results. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a biological test piece, which overcomes the conditions such as keeping microorganisms from light, replenishing water, and being affected by airborne planktonic bacte...
