How Distillation Works: Classic Lab Setup Explained #1368344 (License: Personal Use)

This black-and-white line drawing depicts a classic laboratory distillation apparatus, featuring a round-bottom flask heated over a Bunsen burner, a long delivery tube leading to a spiral condenser immersed in a water bath, and a final collection pitcher catching the condensed distillate. The coiled condenser design maximizes surface area for efficient cooling and phase change from vapor back to liquid. Such setups were historically used for producing spirits, essential oils, and purified solvents.
