Multifunctional fixing frame for colorimetric tube

Abstract

The invention discloses a multifunctional fixing frame for a colorimetric tube. The multifunctional fixing frame comprises a base, wherein a support rod is fixedly arranged on the base; the support rod is arranged vertically; the lower end of the support rod is fixedly connected with the base; the middle part of the support rod is connected with a fixed disk; the fixed disk is sleeved on the support rod; the upper part of the support rod is sleeved with a pressure plate; the pressure plate and the support rod are detachably connected; a plurality of fixed holes are distributed in the fixed plate. The multifunctional fixing frame can not only facilitate the daily placement of the colorimetric tube, but also play a certain dust prevention role. When the colorimetric tube is used for performing water bath heating to carry out a digestion experiment, the multifunctional fixing frame can lock the colorimetric tube, maintain the stability of the colorimetric tube, and ensure the accuracy ofdetection results, the easiness and convenience of operation and the experimental safety.

Description

technical field [0001] The invention relates to experimental equipment, in particular to a multifunctional fixing frame for colorimetric tubes. Background technique [0002] When analyzing heavy metal elements such as mercury and arsenic in water, wastewater, and soil, it is usually necessary to use a colorimetric tube to digest the sample in a boiling water bath. In order to prevent the liquid in the colorimetric tube from leaking during the heating process, the experimenter generally uses gauze Wrap the colorimetric tube stopper and colorimetric tube layer by layer, and then fix the gauze on the outside of the colorimetric tube with string. In this method, the experimenter must bandage the contrast color tubes one by one. This process is time-consuming and laborious, which seriously affects the efficiency of the experiment. [0003] In addition, when the colorimetric tubes are taken out after the boiling water bath digestion is complete, the experimenters have to untie th...

Problems solved by technology

In this method, the experimenter must bandage the contrast color tubes one by one. This process is time-consuming and laborious, which seriously affects the efficiency of the experiment.

[0003] In addition, when the colorimetric tubes are taken out after the boiling water bath digestion is complete, the experimenters have to untie the gauze on the colorimetric tubes one by one, and place them on the colorimetric tube fixing frame after corresponding numbers one by one, which is inconvenient and difficult to operate. long time

Moreover, during the digestion process, the colorimetric tube is often tilted or even tilted in the water bath, which brings unnecessary troubles to the laboratory analysis and has certain potential safety hazards.
