A Simplified Design for a Molecular Still of the Horizontal Type


THE use of the horizontal-type still for molecular distillation has been developed by P. Meunier and Y. Raoul1, and has the advantage of being simple in operation. The present apparatus we have designed eliminates the mechanical part usually attached to the still. Indeed, during operation of the horizontal still, tilting of the apparatus is necessary in order to effect the flow of the liquid along the condenser. This repeated operation results in a gradual concentration of the liquid at one part of the apparatus, thus leaving a big area of the condenser ineffective during the distillation.
