[0002] A chemistry laboratory is an important place that provides conditions for chemical experiments and scientific research. Distillation apparatus is a commonly used device in chemistry laboratories, used for distillation. Distillation is a typical unit operation that was first industrialized to separate homogeneous liquid mixtures. It achieves the separation and purification of components by heating to form a vapor-liquid two-phase system and utilizing the differences in volatility of the components in the mixture.
