Distillation operation: It is often used in distillation experiments, especially for distilling small amounts of liquid. The pear-shaped design allows for more complete evaporation and condensation of the liquid during the distillation process, reduces liquid residue, and improves the purity of the fraction.
Rotary evaporation: It is a common accessory for rotary evaporators. During the rotary evaporation process, the liquid in the flask is heated while rotating, forming a thin film, which increases the evaporation area and accelerates the evaporation rate of the solvent.
Organic synthesis reaction: As a reaction vessel, it is suitable for some organic synthesis reactions that require heating and stirring and have high requirements for the mixing of reactants. The smaller bottle mouth makes it easier to install instruments such as agitators and thermometers to accurately control the reaction conditions.
