Thin Film Evaporator
High efficiency evaporation
AGI Thin Film Evaporator (also known as Wiped Film Evaporator) is ideal for separating volatile components from heat sensitive, viscous and fouling chemical mixtures. Thin film, under low pressure, reduces the boiling point of chemical components, as well as the hydrostatic pressure, resulting in the evaporation of volatile fraction at low temperatures. The PTFE wipers form a thin film on the evaporation column and push the film downwards with every rotation. This causes the heat-sensitive components to experience short residence time on the evaporation area and minimal thermal degradation.
The all-glass design of our Thin Film Evaporator allows for continuous visual monitoring, and the adjustable feed rate provides control over film formation.
Why should you choose a glass thin film evaporator?
A glass evaporator is ideal for process development and troubleshooting applications. An all-glass design ensures high visibility of the process, as opposed to steel evaporators. This means that any undesired events that might occur during process development can be easily observed and rectified.

Customization possibilities
AGI Thin Film Evaporator can be customized and we are happy to discuss the design of custom features with you in order to meet your specific process requirements. Many applications benefit from adjusting the material properties and/or physical size of the evaporator.
AGI Thin Film Evaporator customisation examples
- Fully corrosion resistance models for aggressive chemical mixture separations E.g., using Hastelloy
- Modifications to evaporation surface area e.g., 0.012 m² (DN 45) or 1.5 m² (DN 450)
- Addition of thermal jacket to feed and receiving vessels
