Manual micro-distillation system MRS 255

Apparatus for fractionation of small charge quantities with concentric tube column MRS 255. The special advantage of the concentric-tube-column are: extremely low pressure drop highest separation efficiency minimum hold-up all-glass construction static design (no rotation) The separation efficiency in the concentric-tube-column is based on the physical principle of the mass transfer between vertically rising vapour and the spirally trickling film of liquid in a concentric annular gap made of glass. The column consists of two concentrically melted-in, especially selected and calibrated glass tubes. The Concentric-tube-column is perfectly suitable for the separation of temperature sensitive substances.
