AGI Thin Film Evaporators

High efficiency evaporation
at lab-scale
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.

– Short residence time

– Minimal thermal degradation

– Low pressure of up to 0.1 mbar (abs.)

Wiper system
PTFE wiper blades spread the feed on the evaporation column to form a thin film. The grooves of the wiper blade are angled in such a way that, in addition to thin film formation over the evaporation surface area, it moves the film downwards with every rotation.

- Short residence time on the evaporation surface

- Gentle distillation at low temperature

- Less damage to the heat sensitive chemical fraction 

- Low fouling on the evaporation surface

Evaporation performance
Different components evaporate at different rates in both thin film and short path evaporators. We studied the evaporation rates of different solvent types, which you can see in the graph on the right.

Difference between Thin Film and Short Path Evaporator
The main differences between AGI Thin Film and Short Path Evaporator are the operating pressure and the position of the condenser.

AGI Thin Film Evaporator has an external condenser and can operate from 0.1 mbar (abs.) to atmospheric pressure.

AGI Short Path Evaporator has an internal condenser co-axially positioned alongside the wiper and evaporation surface area. It can operate from 0.001 mbar (abs.) to atmospheric pressure.

The difference in pressure is due to the pressure drop that occurs when the vapor travels from the evaporating area to the condensing area. For our Short Path Evaporator, this distance is shorter compared to our Thin Film Evaporator. This means that AGI Short Path Evaporator can operate at very low pressure compared to AGI Thin Film Evaporator.

Easy installation and dismantling
AGI Thin Film Evaporator can be easily installed without the use of complex tools or steps. The rotary wiper can be easily removed for cleaning and reinstalled.

- Easy to clean and maintain

- Prevents cross-contamination from batch-to-batch
