The Pope Scientific range of distillation and filtration equipment for labs, pilot plants and production processing is available in the UK from Labtex.
With 50 years of design and manufacturing experience, Pope’s short path/wiped film stills, evaporators, molecular stills, fractional distillation columns and Nutsche filter dryers can be found working in R&D laboratories, universities, small & large corporations throughout the world.
The company’s Scientific Short Path/Wiped-Film Stills (WFS) and Wiped-Film Evaporators (WFE) successfully separate volatile from less volatile components for oils, fats, chemicals, polymers, nutraceuticals and fragrances etc. with a gentle process utilising the thin-film wiping action of feed liquid through a heated cylindrical vacuum chamber with high vacuum (i.e. vacuum distillation/evaporation).
Key features include:
- Short residence time of the feed liquid
- Significantly lowered temperature due to high vacuum capability, and
- Optimal efficiency in mass and heat transfer
The brief (seconds) exposure of feed liquid to heated walls is due in part to the slotted wiper design which forces the liquid downward with strict control of residence time, film thickness and flow characteristics.
The Wiped Film-Short Path process for distillation is designed to result in efficient thermal separation with minimum product decomposition and maximum product quality result. The process offers superior performance to flash evaporators, falling film stills, rotary evaporators, and similar equipment in any processing application where heat-sensitivity is a factor.
