Description

Technical Field

[0001] The utility model relates to the technical field of laboratory appliances, in particular to a liquid separation and purification device for multi-stage cleaning of solutions. Background Art

[0002] In the daily laboratory experiments, washing and liquid separation are the most frequently used separation, purification and impurity removal methods, which are usually operated with a separatory funnel. However, if you want to achieve the ideal purification and impurity removal effect in the experiment, you often need to wash, separate and purify multiple times. For example, in the process of making nano calcium carbonate by microemulsion method, it is necessary to transfer the mixed solution that generates calcium carbonate precipitation to a separatory funnel for stratification, take the upper solution and wash it with deionized water for 3 times, add ethanol to precipitate it, and then centrifuge it, and disperse the precipitate in n-hexane to form a transparent solution, so as to obtain the nano calcium carbonate product. The multiple washing process is cumbersome and intermittent, time-consuming and laborious, and many utensils are used, which is easy to cause pollution. In addition, in daily experiments, when the solution is often separated into two layers in the separatory funnel, the target solution to be used is the upper solution. First, the lower solution needs to be discharged, and then the upper solution is discharged. The required drainage time is long, which greatly affects the experimental efficiency.
