Antifouling sampling device for chemical agent for analytical chemistry

Abstract

The invention belongs to the technical field of antifouling sampling devices, and particularly relates to an analytical chemistry agent antifouling sampling device which comprises a bearing plate, a circular truncated cone is fixedly mounted at the top of the bearing plate, a rotating shaft is fixedly mounted at the top of the circular truncated cone, and a rotating table is rotationally connected to the top of the circular truncated cone through the rotating shaft. A connecting plate is fixedly mounted at the top of the rotating table, a fixed support is fixedly mounted at the top of the connecting plate, a penetrating groove is formed in the surface of the fixed support, a center shaft is fixedly mounted through the penetrating groove, a small cylinder is rotationally connected through the center shaft, and a telescopic structure is fixedly connected to the side face of the small cylinder. A fixing ring is fixedly welded to the tail end of the telescopic structure, a suction pipe is fixedly connected through the fixing ring, the device can be rotated by any angle and adjusted by any length, the next sampling operation can be better carried out, and when sampling is needed, the device can be designed to be inclined by any angle, so that the operation is more convenient.

Description

technical field [0001] The invention belongs to the technical field of antifouling sampling devices, and in particular relates to an antifouling sampling device for analytical chemicals. Background technique [0002] Analytical chemistry is a science concerned with the analysis methods and theories of chemical information such as the composition, content, structure, and form of substances. It is an important branch of chemistry. , to determine the relative content of various components, to study the molecular structure or crystal of the substance. [0003] In the process of experimental research in analytical chemistry, it is usually necessary to sample liquid medicines to analyze their specific components. The inside of the tube realizes the sampling of the liquid medicine. Since the sampling tube is directly placed inside the liquid medicine in this way of taking and placing, it is easy to carry various sundries on the sampling tube, and it is easy to cause the whole liqu...

[0003] In the process of experimental research in analytical chemistry, it is usually necessary to sample liquid medicines to analyze their specific components. The inside of the tube realizes the sampling of the liquid medicine. Since the sampling tube is directly put into the liquid medicine in this way of taking and placing, various sundries are easily carried on the sampling tube, which may easily cause the whole liquid medicine to be polluted.
