The Claisen adapter is a laboratory apparatus used in organic chemistry for performing Claisen condensations. It is an adapter that connects two round-bottom flasks of different sizes, with the larger one placed on top and the smaller one placed below. The adapter has two openings, one for the insertion of a thermometer and the other for a condenser.

During a Claisen condensation, the reaction mixture is heated in the larger flask while the smaller flask contains a drying agent to prevent the reaction mixture from becoming too moist. The adapter allows for the reaction mixture to be easily transferred from the larger flask to the smaller flask, where it is allowed to cool and crystallize.

The Claisen adapter is a useful tool for conducting reactions under anhydrous conditions, which is essential for many organic reactions. It can also be used for other types of condensation reactions, such as the aldol condensation.
