Description

Technical Field

[0001] This utility model relates to the field of biological experimental technology, specifically a quantitative sampling device for microbial experiments. Background Technology

[0002] Microbiological experiments are a series of scientific experiments that study the characteristics, behavior, and interactions of microorganisms with their environment. Quantitative sampling in microbiological experiments refers to obtaining a specific volume or weight of sample from a microbial community using standardized methods for quantity determination and analysis. The sampled sample is placed in a sterile container and clearly labeled with its source, sampling time, and date. The sample is then cultured, counted, or subjected to other analyses as needed. For example, the total number of microorganisms in the original sample can be calculated based on the number of colonies formed on the culture medium after dilution. This method effectively enables quantitative sampling in microbiological experiments to accurately assess the quantity and characteristics of microorganisms.

[0003] When sampling microorganisms, tubes are generally used for extraction. However, manual extraction involves many uncertainties that may lead to quantification failure. Furthermore, the extracted microorganisms are placed directly inside the tube, which can cause them to deteriorate due to prolonged exposure to air, affecting the experimental results. Therefore, a quantitative sampling device for microbial experiments with adjustable sampling and built-in storage functions is designed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a quantitative sampling device for microbial experiments, which has the advantages of adjustable sampling and built-in storage functions. It solves the problems that when sampling microorganisms, a tube is usually used for extraction. Manual extraction has many uncertainties that may lead to inability to quantify the samples, and the extracted microorganisms are placed directly inside the tube, which may cause the microorganisms to be exposed to air for a long time, resulting in deterioration and affecting the experimental results.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned objectives of adjustable sampling and self-storage functions, this utility model provides the following technical solution: A quantitative sampling device for microbial experiments, comprising a lower base and an upper base, with a support column installed between the upper and lower bases. A mounting block is fixedly installed at one end of the upper base, and a sampling mechanism is provided at one end of the mounting block. A placement groove is fixedly installed at one end of the lower base, and a support frame is fixedly installed on the upper side of the placement groove. The mounting block is fixedly installed on the upper side of the support frame. A storage bottle is provided on the upper side of the lower base, with one end of the storage bottle located inside the upper base. A rubber stopper is installed on the upper side of the storage bottle. The microbial sample to be sampled is placed inside the placement groove, or the placement groove can be disassembled, allowing the sampling mechanism to perform real-time quantitative sampling. Upon completion of sampling, the collected microbial sample is promptly stored in the storage bottle on one side, significantly reducing the contact between the microbial sample and air.

[0008] Preferably, the sampling mechanism includes a sampling tube, one end of which is installed inside the mounting block, and a threaded rod is installed inside the sampling tube. A piston, rotatably connected to one end of the threaded rod, is installed on the inner wall of the sampling tube. The threaded connection between the threaded rod and the sampling tube provides good stability and allows the piston to move vertically, thereby enabling quantitative collection of microbial samples.

A protective mold is installed at one end of the fixing bolt, which can reduce damage to the outside of the sampling tube and increase the friction between the bolt and the sampling tube.

[0011] Preferably, a sliding groove is installed on the upper side of the upper base, and the upper end of the storage bottle is located inside the sliding groove. A sliding plate with slidable connection is installed on the inner wall of the sliding groove, and a through hole is opened inside the sliding plate. A magnetic pad is fixedly installed on the lower side of the sliding plate, and the magnetic pad is located at the upper end of the storage bottle. The sliding groove is used to install the sliding plate, allowing it to move inside the sliding groove. The through hole is opened inside the sliding plate for installing a sampling tube, which can increase the stability of the sampling tube. When the storage bottle is sealed, a corresponding rubber stopper is installed at its upper end. An iron ring is installed at the upper end of the storage bottle, and the iron ring is located on the inner wall of the storage bottle. The magnetic pad can increase the attraction between the sliding plate and the storage bottle, thereby restricting the position of the sliding plate.

[0012] Preferably, a handle is fixedly installed on the upper side of the sliding plate, and a limit rod is fixedly installed on the inner wall of the sliding groove, with the limit rod engaging at both ends of the sliding plate. The limit rod and the sliding plate are slidably connected. A baffle is rotatably connected to one end of the sliding groove, and a handle is fixedly installed on the upper side of the sliding plate. Moving the handle on the upper side of the sliding plate causes the sliding plate to move along the inner wall of the sliding groove. The limit rod is used to increase the stability of the sliding plate, allowing it to remain stable. The baffle facilitates the removal of the sliding plate, and one end of the baffle is fixed to the sliding groove by a fixing magnet.
