Description

Biological fungus cultivation detection sampling device Technical Field The utility model relates to the technical field of biological bacteria cultivation detection, in particular to a biological bacteria cultivation detection sampling device. Background With the rapid development of biotechnology, the research on microorganisms is getting deeper and deeper. During the cultivation of biological species, samples need to be periodically taken from the culture medium to monitor its growth status or for further analysis. The utility model discloses a microbial agent detection sampling device, which is disclosed in China patent No. CN219670496U and comprises a sampling tube, wherein a fixing plate is fixedly arranged at the top of the sampling tube, a rotating shaft is rotatably arranged in the sampling tube and penetrates through the fixing plate, the liquid to be sampled can be further filtered through a filter screen, the liquid to be sampled is prevented from being stirred when the sampling tube is used for sampling, impurities are led to be taken along with the liquid, the detection result is influenced, the rotating shaft can be prevented from being fixed in a disorder way after rotating the conical tube through a limiting ring, the later stage cannot be aligned to the sampling tube, and the rotating shaft can be connected with the conical tube through a fixing rod, so that the conical tube is driven to be sampled downwards by the rotating shaft. In view of the above related art, the device has some drawbacks in practical use, particularly when treating a sample with a shallow liquid surface. Since its design requires that the liquid must diffuse through the top of the cone into the interior for sampling, this means that it is necessary to ensure that the liquid to be tested has sufficient depth to cover the inlet of the cone during operation, otherwise the sampling process will not be completed effectively. This requirement for liquid depth limits the application range of the device, especially when facing shallow liquid samples, and may lead to sampling failure or insufficient sampling amount, thus reducing the overall use effect and applicability, and therefore, it is necessary to provide a biological bacteria cultivation detection sampling device to solve the above technical problems.
