6″ SS Wiped Film Distillation System
A stainless-steel short-path wiped film system that distills and purifies heat-sensitive botanical fractions in seconds under deep vacuum, with no thermal damage.
Description
The 6″ SS Wiped Film Distillation System is a stainless-steel short-path still for purifying heat-sensitive botanical fractions. A heated rotor spreads the feed into a thin film on the vessel wall, so material evaporates in seconds under deep vacuum and condenses on an internal condenser. The result is a clean, high-clarity distillate with almost no thermal exposure, and stainless steel moves more than double the volume of a comparable glass unit.
Key figures
Thin film, seconds of heat
Feed enters the top of the heated cylinder and a low-speed wiper spreads it into a thin, even film on the inner wall. Under deep vacuum the volatile fraction flashes off almost immediately and condenses on a two-stage internal condenser with a cold trap, while the heavier residue runs down and out through a ball valve.
Because the material is exposed to heat for only seconds rather than the long residence time of a pot still, delicate, heat-sensitive compounds survive the process intact. The short path between evaporator and condenser keeps the operating pressure low, so distillation happens at the lowest possible temperature.

Frequently asked questions
A short-path technique where the feed is spread into a thin film on a heated wall and evaporated in seconds under vacuum, then condensed nearby. It purifies heat-sensitive material with minimal thermal exposure.
A pot still holds material at heat for a long time, which degrades delicate compounds. Thin film exposes it for only seconds, so the distillate stays cleaner and higher quality.
Roughly 2.0 to 5.0 litres per hour, fed in 5 L manual batches, with continuous discharge through a ball valve.
The evaporator runs up to 225 °C and the system pulls down to an ultimate vacuum of 1.0 Pa, with a dual-stage pump reaching 1 × 10⁻³ mbar.
304 stainless steel with a food-grade polished interior, PTFE flat seals and Pt100 sensors, controlled by a PLC.
