PILODIST MRS 255 Micro-Distillation

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.
