Description

Technical Field

[0001] The utility model relates to the field of laboratory equipment, in particular to a colorimetric tube rack used for high-temperature digestion. Background Art

[0002] In the fields of chemical analysis, environmental monitoring, and biological sciences, high-temperature digestion experiments are common sample pretreatment methods. This method uses a high-temperature and high-pressure environment to quickly dissolve or decompose organic and inorganic substances in the sample, providing convenience for subsequent analysis and testing. However, in high-temperature digestion experiments, how to ensure the safety and stability of colorimetric tubes and prevent them from breaking or leaking due to high temperature and high pressure has always been a challenge faced by experimenters.

[0003] At present, there are many experimental equipment for high-temperature digestion on the market, such as high-pressure digestion pots, microwave digestion instruments, etc. These equipment not only provide a high-temperature and high-pressure environment, but are also equipped with corresponding sample containers, such as digestion tubes, colorimetric tubes, etc. However, these sample containers often have the following problems during high-temperature digestion: the top of the container is not tightly sealed, causing the sample to leak or evaporate at high temperature, affecting the experimental results.

[0004] Most existing methods for solving this problem are to strengthen the connection between the colorimetric tube plug and the colorimetric tube, such as wrapping a reinforcing material around the outside of the colorimetric tube plug. However, under high temperature and high pressure conditions, the colorimetric tube plug will still pop out, resulting in inaccurate experimental data. Utility Model Content

[0005] In order to solve the above problems, an embodiment of the utility model provides a colorimetric tube rack capable of preventing the plugs of colorimetric tubes from popping out during a high-temperature digestion experiment.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a colorimetric tube rack for high-temperature digestion, comprising a base, a positioning module for fixing the colorimetric tube is arranged in the base, and a pressure cover for pressing the colorimetric tube is arranged above the base.

[0007] As a further improvement of the above technical solution:

[0008] The base comprises a bottom plate, support rods are arranged on both sides of the bottom plate, and the positioning module is detachably connected to the support rods.

[0009] The positioning module comprises a partition plate arranged parallel to the bottom of the base, the partition plate is provided with a through hole for passing the colorimetric tube, and the support rod is provided with a positioning pin for connecting the partition plate.

[0010] A cross bar is arranged above the pressure cover, and two ends of the cross bar are respectively detachably connected to two support rods.

[0011] A threaded hole is arranged in the middle of the crossbar, an adjusting screw is arranged in the threaded hole, and a connecting sleeve corresponding to the position of the adjusting screw is arranged on the upper part of the pressure cover.

[0012] The bottom of the base and the lower surface of the pressure cover are both provided with buffer pads.

[0013] The beneficial effects of the embodiments of the utility model are as follows: 1. The colorimetric tube rack for high-temperature digestion includes a base, a positioning module for fixing the colorimetric tube is arranged inside the base, and a pressure cover for pressing the colorimetric tube is arranged above the base. The design of the pressure cover can enhance the fixation of the colorimetric tube plug. Compared with the existing method of increasing the connection strength with the colorimetric tube by wrapping cotton cloth around the outside of the colorimetric tube plug, the design of the pressure cover can more directly and effectively prevent the colorimetric tube plug from popping out during the high-temperature digestion process, and the structure is simple, and multiple colorimetric tube plugs can be pressed at one time. Compared with the conventional method, the time used is shorter, which improves the working efficiency.

[0014] 2. A cross bar is provided above the pressure cover, and both ends of the cross bar are detachably connected to two support rods. A plug-in sleeve is provided at one end of the cross bar, and a positioning pin used in conjunction with the plug-in sleeve is provided at the upper end of one of the support rods. A locking bolt is provided at the other end of the cross bar, and a threaded sleeve used in conjunction with the locking bolt is provided at the corresponding upper end of the support rod. When the colorimetric tube needs to be installed, the locking bolt is opened, and then the pressure cover is rotated to one side to avoid the position. Alternatively, both ends of the cross bar can be connected to the cross bar by locking bolts. When the colorimetric tube needs to be installed, the two locking bolts can be opened to remove the pressure cover. BRIEF DESCRIPTION OF THE DRAWINGS
