A New Apparatus for the Collection of Tobacco Smoke for Producing Native Tobacco Tar / Eine neue maschinelle Abrauch- und Rauchabscheidungsapparatur zur Gewinnung von „nativem“ Tabakteer

In our opinion mechanical smoke collection traps do not make sufficient allowance for the particular chemical and physico chemical properties of tobacco tar and its constituents, and, therefore, do not produce the tar in its original state. For this reason a new apparatus has been designed which compared to other processes makes it possible to collect the tobacco smoke in a solvent. Our experience has shown that this is the only practicable method of producing a tobacco tar which as far as possible remains unchanged by chemical reactions and is suitable for biological tests. The tobacco smoke is washed out by the solvent in a wash bottle and a suitably diluted tar solution is obtained which is drawn off intermittently. The specially designed smoking apparatus is separately mounted on top so that the smoke passes into the wash bottle by the shortest possible route. The entire machine is built into a framework of angle iron and is mounted on vibration dampers to eliminate oscillation. It enables a large number of cigarettes to be smoked in a very short time
