Round-Bottom Flask - Laboratory Glassware for Chemical Reactions #1458682 (License: Personal Use)

This illustration depicts a standard round-bottom flask made of heat-resistant borosilicate glass, featuring a spherical base to distribute thermal stress evenly during heating. The flask includes a narrow neck sealed with a blue rubber or plastic stopper, commonly used in distillation setups, reflux reactions, and solvent evaporation. Its design prevents localized overheating and allows efficient stirring or connection to condensers and adapters.
