compared with the existing detection vessel, the microorganism rapid culture detection vessel for food microorganism detection provided by the utility model has the advantages that the detection vessel can be rapidly cultured and detected by rotating the threaded cover, can lead the screw cap to be in threaded connection with the culture dish, ensures that nutrient solution in the culture dish cannot spill when moving and needs to be detected, researchers can press the straw with one hand and pull the pull ring outwards with the other hand, so that the slide block on the connecting rod in the straw can do linear movement in the longitudinal direction, in the process that the slide block slides upwards, nutrient solution is sucked into the suction pipe under the influence of atmospheric pressure, researchers can take out the suction pipe at the moment, align the lower end of the suction pipe opening to the detection plate and then push the pull ring downwards to enable the nutrient solution in the suction pipe to flow onto the detection plate, operation and control are facilitated, thereby solving the problem that the prior art is not easy to control when directly pouring the nutrient solution in the culture dish into the detection plate.

The utility model provides a food microbiological examination is with microorganism fast cultivation detection household utensils, through the sealing washer on the slider, can remove the in-process at the slider, ensure the straw inner wall and do not receive the damage, still do benefit to the air in the discharge straw.

The utility model provides a food is microorganism fast cultivation and detection household utensils for microbiological examination, the baffle can ensure when not using the straw, and the straw can not fall into in the culture dish.

The utility model provides a food is microorganism fast cultivation and detection household utensils for microbiological examination puts the insulation cover through the cover on the culture dish, can maintain the temperature in the culture dish, is favorable to the growth of microorganism.

The utility model provides a food microbial detection is with microorganism fast cultivation detection household utensils through the scale plate on the heat preservation cover, is favorable to the researcher to inhale accurate nutrient solution content with the straw.
