The invention discloses a microbial
flora screening device, and particularly relates to the field of microbial culture.The microbial
flora screening device comprises an external placement disc, the top end of the external placement disc is fixedly connected with a corresponding clamping frame, the top end of the corresponding clamping frame is fixedly connected with two sets of fixing columns, the interior of the corresponding clamping frame is fixedly connected with a spring, and one end of the spring is fixedly connected with a clamping clamping block; when the
piston positioning push block drives the inclined pushing spring to make contact with the bottom end of the interior of the hollow
piston pipe, the inclined pushing spring is in a compressed state under the pressure of the inner wall of the hollow
piston pipe, the medicament is converted into mist through the
assembly mist spraying performance of the mist spraying connector, and the mist spraying connector located at the upper corresponding through-flow hole sprays upwards; the spraying position sprays towards a farther position due to spraying
inertia, and the spraying connectors located at the lower corresponding through-flow holes spray downwards, so that the microbial colonies located under the spraying position provide nutritional agents, survival agents are comprehensively provided for the microbial colonies, and a good survival environment is provided for the microbial colonies.
