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.
