Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the present invention is described clearly and completely.

[0035] Such as figure 1 As shown, a laboratory acid tank device includes a cylinder body 1, which is a cuboid structure, and the acid liquid used for cleaning glassware is filled in the cylinder body, and the height of the acid liquid is usually less than or equal to half of the height of the cylinder body. The body 1 is provided with a cover 2, which is used to seal the cylinder body to prevent the evaporation and volatilization of the acid liquid. The cover is also provided with a handle 21, an air inlet valve 22, and a liquid filling hole 23, and the liquid filling hole 23 is covered Has hat 24. When adding liquid to the cylinder, you can open the cap, use the liquid filling hole to add acid or neutralizing lye into the cylinder, and insert the stirring head into the liquid filling hole for stirring operation, effectively preventing the liquid from splashing ...

Abstract

The invention discloses an acid cylinder device for a laboratory, which comprises a cylinder body, acid liquor for cleaning glassware is contained in the cylinder body, a cover is arranged on the cylinder body, a bracket is obliquely and fixedly arranged on the outer wall of the cylinder body, a hooking tool for taking and placing the glassware is movably placed on the bracket, and the hooking tool comprises a long rod; a handle is arranged at the tail of the long rod, a straight hook is fixedly connected to the head of the long rod, the included angle between the straight hook and the long rod ranges from 60 degrees to 120 degrees, and the length of the long rod is larger than or equal to the height of the cylinder body. According to the acid cylinder device, the operation of taking and placing glassware by experimenters is greatly facilitated, and the harm of acid liquor to human bodies is remarkably reduced.

Description

technical field [0001] The invention specifically relates to an acid tank device for a laboratory, belonging to the technical field of chemical detection. Background technique [0002] In the chemical detection laboratory, it is often necessary to analyze and determine the trace elements in the sample, such as the analysis and determination of the content of heavy metal elements in the water sample. In the process of determining trace substances, it is necessary to avoid the pollution introduced by the glassware itself as far as possible. Usually, the glassware needs to be specially treated before the measurement—acid bubble. The types of acids used in acid bubbles are also different according to the measurement items. Nitric acid is generally used for the determination of metal content in samples; sulfuric acid is generally used for the determination of organic substances in samples; hydrochloric acid is generally used for the determination of biological and nutrient salts...
