With concentric tube column MRS 255.
Apparatus for fractionation of small charge quantities.
The special advantage of the concentric-tube-column are:
extremely low pressure drop
highest separation efficiency
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.

Mains supply: 230 V, 50 – 60 Hz
Weight: approx. 31 kg
Dimensions (w x h x d): approx. 0.90 x 0.75 x 0.50 m
