Description

Technical Field

[0001] The utility model relates to the technical field of magnetic stirring separation equipment, in particular to a magnetic stirring separation equipment for purifying laboratory water samples. Background Art

[0002] In laboratory research, the analysis and testing of water samples is an important part of obtaining water quality information, assessing environmental conditions, and conducting various scientific experiments. As a necessary pretreatment step before analysis and testing, water sample purification directly affects the accuracy and reliability of subsequent experimental results.

[0003] Traditional laboratory water sample purification methods and equipment have exposed many problems in practical applications. On the one hand, the conventional stirring equipment has a single function, and it is impossible to ensure that the purification reagent is evenly dispersed in the water sample during the stirring process, resulting in insufficient purification reaction, making it difficult to completely remove the pollutants in the water sample, seriously affecting the purification effect. For example, when treating industrial wastewater samples containing a variety of complex pollutants, due to uneven stirring, the concentration of purification reagents in some areas is too low, and it is impossible to fully react with the pollutants, thereby reducing the overall purification efficiency and quality. On the other hand, the existing separation means are cumbersome and complicated to operate. During the separation process, the experimenter is often required to manually transfer the water sample many times, which not only consumes a lot of time and energy, but also easily introduces external impurities during the operation. For example, when using filter paper to filter and separate impurities, if the operation is improper, the filter paper may break, causing impurities to mix into the purified water sample; or in the process of pouring the water sample, impurities such as dust in the surrounding environment may fall into the water sample, interfering with subsequent experimental analysis, and failing to provide high-quality purified water samples for scientific research. Therefore, those skilled in the art provide a magnetic stirring separation device for laboratory water sample purification to solve the problems raised in the above background technology.
