destillatsioonipäässe

Destillatsioonipäässe, a Finnish term, translates to "distillation head" or "distillation adapter" in English. It refers to a component used in distillation apparatus, specifically connecting the distillation flask to the condenser. Its primary function is to facilitate the efficient transfer of vapor from the boiling liquid to the cooling surface of the condenser, where it will condense back into a liquid.

This piece of glassware typically features one or more side arms. The main vertical connection allows vapor to rise from the distillation flask. A side arm, often positioned at an angle, serves as the entry point to the condenser. Depending on the specific distillation technique, destillatsioonipäässe might also include additional ports. These can be for inserting a thermometer to monitor vapor temperature, a reflux condenser, or for the addition of reagents during a reaction.

The design of a destillatsioonipäässe can vary. Simple versions are straightforward adapters, while more complex designs might incorporate features like distillation columns or Vigreux indentations to increase surface area and improve separation efficiency. The material is typically heat-resistant glass, such as borosilicate glass, to withstand the temperatures involved in distillation. Proper sealing of the destillatsioonipäässe to the flask and condenser is crucial for preventing vapor loss and ensuring accurate results.
