Embodiment Construction

[0028] The funnel-shaped digestion tube plug body proposed by the present invention has a plug body that can extend to the inside of the digestion tube, and a connecting portion arranged on the upper part of the plug body. The inner wall of the funnel-shaped digestion tube plug body is in the shape of a tapered funnel, the bottom forms a drain hole, and the outer peripheral surface of the connection part forms a columnar body that matches the mouth of the digestion tube. The present invention overcomes the defects in the prior art by extending the plug body into the digestion tube, and connecting the connection part with the digestion nozzle well, thereby effectively controlling the loss of reagents in the digestion tube during the high-temperature digestion process. Volatility, no need to remove the plug body when adding digestion solution, suitable for automatic liquid addition operation of automatic digestion instrument.

[0029] In addition, the outer peripheral surface of...

Abstract

The invention relates to a funnel-shaped digestion tube plug body which is provided with a plug body and a connecting part, wherein the plug body can extend into a digestion tube; the connecting part is arranged at the upper part of the plug body; the inner wall of the funnel-shaped digestion tube plug body takes the shape of a cone funnel; a drainage hole is formed in the bottom of the funnel-shaped digestion tube plug body; and a cylindrical object matched with a tube orifice of the digestion tube is formed on the outer peripheral surface of the connecting part. According to the invention, the full-automatic control of a digestion system in the digesting process can be met; a reagent can be automatically added into the digestion tube without taking down the plug body; the volatilizing quantity of the reagent in the digestion tube in the high temperature digesting process is also reduced; the condensation reflux quantity of the reagent is effectively increased; the pollution to the air is reduced; and the operation safety is improved.

Description

technical field [0001] The invention relates to a digestion pipe plug body, in particular to a funnel-shaped digestion pipe body which is convenient for adding liquid into the digestion pipe and can increase the condensed return flow rate of the liquid in the digestion pipe. Background technique [0002] Digestion: also known as wet digestion, is a method of destroying organic or reducing substances in a sample by using acid or lye and heating. Digestion tube: Equipped with graphite digestion instrument, it is used to hold the sample to be digested and the acid (alkali) solution. The material is generally polytetrafluoroethylene (PTFE). [0003] At present, the digestion tubes equipped with known graphite digestion instruments are all open-ended design, and the volatilization of reagents cannot be controlled during the high-temperature digestion process. 1. The concentrated alkaline solution is distributed from the digestion tube into the experimental space, which will not ...
