Asahi-Thin Film Evaporator-Blue Label

For heat sensitive, high boiling products, and high molecular weight materials! This apparatus can make uniform thin-film. You can choose the standardized (Blue Label) or custom-made (Gold Label) product depending upon your needs.


Minimum Thermal Decomposition Perfect for Highly viscous products & Heat sensitive products
Natural compound
High Evaporation Efficiency Easy to be evaporated
Uniform Rotating Wiper System The thin film is formed by the centrifugal force for shorter residence time.
Uniformed Thin Film Higher Evaporation Efficiency
The uniform liquid film is created on the heating surface via the use of glass tube.
Grease-less Monitor the Process Visually The main body of the evaporator is made of Borosilicate glass 3.3.
Greaseless Valve and Joints No Contamination
Easy Installation
Grease-less Magnetic Sealed Bearing Gas & Vacuum tight
Consistent torque throughout entire temperature range
Easy cleaning and maintenance
Maximum Jacket Temperature Temperature Range Up to +230℃
Upgradable up to + 300 ℃ when changed wiper, gasket and o-rings
Easy connection to equipment The system can be easily connected to the existing overhead stirrer, thermostat and vacuum pump.
(Not include overhead stirrer, thermostat and vacuum pump)
