Flat-bottom flasks have a stable, flat base, making them ideal for use on lab benches and heating plates. They are commonly used for stirring and mixing. Round-bottom flasks, with their curved base, are designed for even heating and efficient mixing, making them suitable for distillation and reflux processes. The choice between them depends on the experimental requirements and stability needs.
