PILODIST® HRS 500 C semi-micro distillation

PILODIST® manufactures the world famous concentric-tube-column (CTC), an especially versatile distillation column with highest separation efficiency.

The special advantages of the concentric-tube-column are:

  • extremely low pressure drop
  • highest separation efficiency
  • minimum hold-up
  • all-glass construction
  • static design (no rotating parts inside the column)

The separation efficiency in the concentric-tube-column is based on the physical principle of the mass transfer betwen 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.
