Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of laboratory containers, and in particular relates to a reagent sampling device. Background Art
[0002] The reagent sampling device is a device used to sample from a chemical reagent bottle or container. Its main function is to accurately and conveniently obtain the required reagents and ensure the safety and accuracy of the sampling process. The development of the reagent sampling device has undergone a long evolution and is closely related to the course of social development. The sampling of reagents mainly relies on simple manual operations, such as pouring the reagents directly from the bottle mouth or scooping them with a vessel. This method is simple to operate but not accurate enough, and it is easy to cause waste and pollution of reagents. With the advent of the industrial revolution, chemical experiments and production activities have increased significantly, and higher requirements have been placed on the accuracy and efficiency of reagent sampling. Therefore, people began to develop various sampling tools to more accurately control the amount and flow of reagents.
[0003] In the industrial production process, some chemicals are essential raw materials or intermediates, but they may have certain toxicity. During the production process, these toxic chemicals need to be sampled and analyzed to ensure the safety of the production process and the quality of the product. Toxic and corrosive reagents have high safety risks and may cause serious harm to the human body. In actual operation, suction is usually used to sample reagents, which requires the use of two hands at the same time. Using two hands to sample at the same time may increase safety risks. When people handle reagents with two hands at the same time, they may not be able to fully grasp the stability of the reagent container, causing the container to slide or tilt, increasing the risk of splashing or leakage. In this case, the reagent may splash onto the human body or the surrounding environment, increasing the possibility of accidental injury.
[0004] In summary, when sampling toxic reagents, there is a problem that the reagents may drip from the sampling port, endangering personal safety. Utility Model Content
[0005] In view of this, the utility model provides a reagent sampling device, which can solve the problem that when sampling toxic reagents, the reagents may drip from the sampling port and endanger personal safety.
[0006] The utility model is achieved in this way:
[0007] The utility model provides a reagent sampling device, which comprises an air bag, a suction tube and a sampling head, wherein the air bag is fixedly connected to one end of the suction tube, the other end of the suction tube is fixedly connected to the sampling head, the air bag is connected to a collection bucket through a connecting rod, a baffle is sleeved on the suction tube, the air bag is used to control the sampling speed, the sampling head is used for sampling, and the suction tube is used to drain and store the sampled reagent.
[0008] The technical effects of a reagent sampling device provided by the utility model are as follows: by setting an air bag, fingers can be prevented from directly contacting the reagent, thereby reducing the risk of contamination that may be introduced, and the corrosive effect of the reagent on the human body can also be avoided. The air bag enables sampling to be operated with one hand, especially when frequent sampling or operation of other instruments is required, so that experimental work can be carried out more efficiently. Single-handed operation reduces the time and action of changing hands, saving the time of experimental operation, especially when a large number of samples are taken or high-frequency operations are performed, which can significantly improve work efficiency. By setting a collection barrel, the sampling reagent can be effectively stored and can be easily removed, which is convenient for transferring a large amount of reagents at one time.
[0009] On the basis of the above technical solution, a reagent sampling device of the utility model can also be improved as follows:
[0010] Wherein, the sampling head is a cylindrical structure, and a plurality of through holes are arranged on the sampling head, and the through holes are evenly arranged on the sampling head.
[0011] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the multiple through holes enable the sampling head to absorb liquid from different angles, thereby increasing the flexibility and applicability of the operation. The multiple through holes can absorb more liquid at the same time, thereby improving the efficiency of sampling. In particular, in the case of large-scale sampling or rapid operation, the operation time can be reduced and the work efficiency can be improved.
[0012] Furthermore, a blocking piece is sleeved on the suction tube, and the blocking piece is slidably connected to the suction tube.
[0013] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting the baffle, the position of the baffle can be flexibly adjusted to prevent the corrosive reagents from contacting the skin after the entire device is turned over, which may cause burns, irritation or other adverse reactions. The use of the baffle can effectively prevent these substances from flowing onto the hands of people, thereby protecting the health and safety of the experimenters.
[0014] Furthermore, the blocking piece is a semicircular structure, and the blocking piece is a structure that is thick in the middle and thin around the edges.
[0015] The beneficial effects of adopting the above-mentioned improved solution are as follows: the design of the baffle can provide stronger protection, effectively preventing liquid from splashing or flowing to undesired areas, thereby protecting experimenters from contact with harmful liquids. The middle part is thicker, and the overall stability of the baffle is higher, and it is not easy to deform or move.
[0016] Furthermore, the connecting rod is fixedly connected to one end of the airbag, and the other end of the connecting rod is rotationally connected to the collecting barrel via a thread.
[0017] Furthermore, the collecting bucket is provided with a scale.
[0018] Furthermore, the suction tube is made of glass.
[0019] The beneficial effect of adopting the above-mentioned improvement scheme is that the transparent glass facilitates observation of the volume of the sampled liquid.
[0020] Furthermore, the diameter of the through hole is 1-2 mm.
[0021] Furthermore, the through hole is circular in shape.
[0022] Furthermore, the through hole is elliptical in shape.
[0023] Compared with the prior art, the reagent sampling device provided by the utility model has the following beneficial effects: by setting up an air bag, fingers can be prevented from directly contacting the reagent, thereby reducing the risk of contamination that may be introduced, and the corrosive effect of the reagent on the human body can also be avoided. The air bag enables sampling to be operated with one hand, especially when frequent sampling or operation of other instruments is required, and experimental work can be carried out more efficiently. Single-handed operation reduces the time and action of changing hands, saving the time of experimental operation, especially when a large number of samples are taken or high-frequency operations are performed, which can significantly improve work efficiency. By setting up a collection barrel, the sampling reagent can be effectively stored and can be easily removed, which is convenient for transferring a large amount of reagents at one time.
