Advance to Anschütz-Thiele

Distillation advance according to Anschütz-Thiele with NS 29/32 connections for the condenser (top left) and the receiver flask that can be exchanged during the distillation (bottom).

The thrust to Anschütz- Thiele , also thrust by Thiele-Anschiitz called, is a glass dish in chemical laboratories, which allows for a vacuum distillation to remove any number of fractions, without the vacuum to have to pick up during the distillation. This is done using three valves or vacuum cocks.

The Anschütz-Thiele is of great importance in preparative organic chemistry for the separation of high-boiling mixtures by distillation on a laboratory scale. It is named after the chemists Richard Anschütz and Johannes Thiele . A device that is the same in function but slightly different in design is the Perkin triangle, which is used in the English-speaking area.

A simpler alternative to the Anschütz-Thiele in terms of operation and design is the spider .
