レトルト(蒸留器具)
A device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. 

The liquid to be distilled is placed in the vessel and heated. The neck acts as a condenser, allowing the vapors to condense and flow along the neck to a collection vessel placed underneath.
