    Round Bottom Flasks

    Round Bottom Flasks

    Specifically shaped for constant heat distribution, the round bottom flasks are used for distillation, chemical reactions, heating liquid sample, and storage demands. Manufactured from resistant glass, the spherical containers will spread encountered stress evenly across surfaces to stop fracturing. Built with temperature resistance, the glassware is a necessary piece in reflux set-ups. Mainly used for chemical and biochemical research, the round bottom flasks have short or long neck options.

    Frequently Asked Questions

    Round-bottom flasks are typically used in labs for heating liquids and conducting chemical procedures that need consistent heat distribution, such as distillations and reflux reactions. Their spherical shape provides even heating, eliminating the possibility of localized overheating or "hot patches"

    Flat-bottom flasks are multipurpose lab instruments that are mostly utilised for distillation, light heating, basic chemical reactions, and liquid storage. Without the need for additional supports, they may stand straight on a bench or hot plate thanks to their stable flat base.

    The main purpose of the round-bottom flask in simple distillation is to serve as a vessel for distillation. It is heated and contains the liquid mixture to be distilled, which enables the more volatile component to evaporate and condense in a different collector.
