Pope Scientific, Inc. Pope 2" Wiped-Film Molecular Still 40468-02

Efficient thermal separation with minimum product decomposition and maximum product quality; these are results you can expect using Wiped Film - Short Path process for distillation, evaporaton, concentration, separation, purification or deodorization. Performance is superior to flash evaporators, falling film stills, rotary evaporators and other equipment, in any processing application where heat-sensitivity is a factor. Pope Short Path/Wiped-Film Stills (WFS) and Wiped-Film Evaporators (WFE) successfully separate volatile from less volatile components with a gentle process utilizing the thin-film wiping action of feed liquid through a heated cylindrical vacuum chamber. Keys to the superiority of this process include short residence time of the feed liquid, a 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. 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.
