Wiped-Film Stills & Evaporators

Pope Scientific designs and fabricates basic to complex systems using the wiped-film short-path distillation process (also called thin-film distillation) for stills, evaporators and hybrid configurations that include fractional columns with wiped-film distillation units, centrifugal molecular distillation units, vacuum distillation, condensers, evaporation and processing vessels that meet our customer’s application requirements, with superior results.

Equipment for Molecular Distillation Under High Vacuum
Pope 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, Fragrances, etc., with a gentle process utilizing the thin-film wiping action of feed liquid through a heated cylindrical vacuum chamber with high vacuum (i.e. vacuum distillation/evaporation).

Superior Distillation Process For Liquid Separation and Chemical Purification
Efficient thermal separation with minimum product decomposition and maximum product quality are results you can expect using this Wiped Film-Short Path process for distillation, evaporation, concentration, separation, purification or deodorization. The Wiped Film process offers far superior performance to flash evaporators, falling film stills, rotary evaporators and similar equipment, in any processing application where heat sensitivity is a factor.

High quality components, state-of-the-art fittings and materials, and total quality control during all phases of design, fabrication and testing result in processing equipment offering the highest performance possible.
