Glass Wiped Thin Film Evaporator

Efficient Solvent Recovery, Perfected by Precision

GWF Glass Wiped Thin Film Evaporator

LAB1ST Glass type Thin Film Evaporator, also known as a Wiped Film Evaporator, is designed for the efficient separation of volatile components from heat-sensitive, viscous, and fouling mixtures. By operating under low pressure, it reduces the boiling point and hydrostatic pressure, enabling the evaporation of volatile fractions at lower temperatures. PTFE wipers ensure a uniform thin film on the evaporation column, minimizing thermal degradation with short residence times.

Key Facts 

​​​

  • Short residence time

  • Evaporation area: 0.1~0.35㎡

  • Heating temperature: RT~250℃

  • Low pressure of ≤0.1Pa [no load], operation vacuum ≤0.1 mbar (abs.)

  • All-glass design allows continuous visual monitoring

Glass wiped film evaporator unit provides a customizable evaporation area ranging from 0.1 to 0.35 ㎡, allowing for flexible operation and efficient processing of various batch sizes to suit different applications. Incorporates a magnetic sealing system that ensures a high vacuum environment, reducing the boiling points of substances and enabling low-temperature evaporation to protect delicate compounds from thermal degradation.

GWF Series

  • High Efficiency: The evaporator is designed to maximize heat transfer with a thin film of liquid on a heated surface, allowing for faster evaporation rates and greater energy efficiency.

  • Low Operating Temperatures: The equipment is capable of operating at reduced pressures, which lowers the boiling point of the liquid and allows for evaporation at much lower temperatures.

  • Short Residence Time: The design of the thin film evaporator ensures that the material spends minimal time on the heated surface, which minimizes the risk of thermal degradation and ensures a higher quality final product.

  • Versatility: Handing a wide range of viscosities and are suitable for processing a variety of materials, from light solvents to high-viscosity resins.

  • Easy to Operate and Clean: The evaporator is designed for ease of operation and cleaning, with a modular design that allows for easy access to internal components.

  • Customizable Configurations: LAB1ST offers customizable options to meet specific industry requirements, such as different heating options (electric, steam, etc.), various materials of construction, and varying capacities.
