Description

Technical Field

[0001] The utility model belongs to the technical field of experimental tools for chemical analysis, in particular to a beaker set for chemical laboratories. Background Art

[0002] Beaker is a common glassware in the laboratory, mainly used for solid-liquid mixing, evaporation and concentration, dissolving substances and chemical reactions. In the experimental process of heating and dissolving solid samples, most samples need to be heated and dissolved for a long time (more than 12 hours) to ensure that the reaction is fully carried out and there are no residual insoluble particles. Then, remove the beaker containing the test solution from the heating device, let it cool to room temperature and proceed to the next step.

[0003] At present, the following problems exist in the experimental process: most solid samples are dissolved in liquid solvents. Because the experiment requires heating and dissolution time is too long, the liquid in the beaker is seriously vaporized and the liquid evaporates; the sample is dissolved at high temperature, and because the liquid evaporates too quickly, new liquid solvent is continuously added during the dissolution process, which may bring in impurities and cause contamination; the beaker containing the test solution lacks a fixed placement point during the cooling process, causing contamination and waste of the test solution; there may be tiny particles that are not completely dissolved in the beaker or tiny chemical reactions continue to occur. Due to problems with the observation position and angle, they cannot be clearly observed and identified, resulting in incomplete dissolution of the sample. Utility Model Content
