Condensers, Liebig, B19/25 effect 250 mm

A condenser is a piece of laboratory glassware used to cool and condense vapours back into liquid during distillation or reflux processes. It typically consists of an inner tube carrying the vapour and an outer jacket through which cold water flows to remove heat. Condensers help improve efficiency, prevent loss of product, and maintain controlled reactions. Different types (e.g., Liebig, Allihn, Graham) offer varying cooling efficiency depending on the experiment.
