Chemical experiments: In organic synthesis, inorganic synthesis and other experiments, it is used to accurately control the dripping speed and dosage of liquid reagents to control the reaction process and improve the reaction yield.
Separation and purification: Using its liquid separation function, it can separate immiscible liquid mixtures, such as separating oil and water from oil-water mixtures; it can also be used for extraction operations to extract target substances from mixtures.
Gas preparation: In some gas preparation experiments, liquid reactants can be dripped into the reaction vessel through a constant pressure separatory funnel, while balancing the system pressure to ensure the safety and smooth progress of the experiment.
