Device for positioning and aligning a distillation flask in a distilling device

摘要

The device has a controlling and regulation unit for controlling and varying an operation size of a calorific element, such as temperature or electric output of the element to obtain distillation parameters in accordance with a chosen preset standard. An articulated stopper (11) is integrally mounted on a frame (1) of a distilling apparatus, where the stopper cooperates with a spherical shaped coupling end fitting (13) that is fixed on a closure cap (10) and ratchets to an internal part of the stopper.
