Round Bottom Flasks
Specifically shaped for uniform 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 prevent fracturing. Built with temperature resistance, the glassware is an essential piece in reflux set-ups. Primarily used for chemical and biochemical research, the round bottom flasks have short or long neck options.
