Embodiment Construction
[0022] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.
[0023] refer to figure 1 , The first specific embodiment of the present invention provides a digestion colorimetric tube 100 , and the digestion colorimetric tube 100 includes a first tube body 110 , a second tube body 120 and a third tube body 130 . Wherein, the second tube body 120 and the third tube body 130 are located at two ends of the first tube body 110 . The inner diameters of the second tube body 120 and the third tube body 130 are smaller than the inner diameter of the first tube body 110 . A plurality of fixing columns are arranged on the first pipe body 110, such as figure 1 The figure shows a situation where there are four fixed posts, and the fixed posts are the first fixed post 141 , the second fixed post 142 , the third fixed post 143 and the fourth fixed post 144 . The plurality of fixing posts are arrange...

Abstract
The invention provides a digestion colorimetric pipe and digestion colorimetric system. The digestion colorimetric pipe comprises a first pipe body as well as a second pipe body and a third pipe body which are located at double ends of the first pipe body. The internal diameter of the second pipe body and the internal diameter of the third pipe body are less than the internal diameter of the first pipe body. The first pipe body is provided with multiple fixed columns. Multiple fixed columns are alternatively arranged on double opposite sides of the first pipe body at the extension direction of the first pipe body. The second pipe body is provided with several first positioning projections and second positioning projections. The first positioning projections are alternately arranged at one side of the second pipe body at the extension direction of the second pipe body. The second positioning projections are alternately arranged at the other side of the second pipe body and are opposite to the first positioning projections. The digestion colorimetric pipe and the digestion colorimetric system have the characteristic of high heat conduction efficiency, and heating digestion and colorimetric analysis can be carried out simultaneously.
Description
technical field [0001] The invention relates to the technical field of environmental water quality monitoring, in particular to a digestion colorimetric tube and a digestion colorimetric system applicable to environmental water quality monitoring. Background technique [0002] Digestion refers to the use of strong acid or strong base to react the sample under heating conditions to decompose the organic matter or destroy the reducing substances in it, and oxidize the elements of various valence states into a single high valence state or transform them into easily separated inorganic substances. Compounds, while allowing the sample to be concentrated (that is, clear and transparent without precipitation) to facilitate the process of analysis and determination. In the prior art, straight glass tubes are often used for digestion or colorimetry of samples. When heating and digesting, most of them use air heat conduction. The way of using air heat conduction has the defects of l...
