    • PTFE and fluororubber dual sealing ensure high vacuum degree.
    • The exhaust nozzle of the condenser is positioned below for safer connection with the vacuum tube.
    • The rotary vacuum evaporator has a modular design with strong scalability.
    • Convenient lifting operation to avoid movement of the glass parts, ensuring safety and ease of use.
    • The rotational speed and bath temperature are displayed digitally and controlled by PID for high temperature control accuracy.
    • The bath is separated from the 2L rotary evaporator, allowing flexible configuration.


    Rotary evaporators are commonly used in laboratories and industries for efficient solvent evaporation and concentration processes, such as in pharmaceutical research, chemical synthesis, and essential oil extraction.

    Rotary evaporator applications

    Tips: What is the difference between a vertical and a horizontal condenser in a rotary evaporator?

    Vertical Condenser:

    • Orientation: A vertical condenser is positioned vertically above the boiling flask of the rotary evaporator.
    • Design: It consists of a long, vertically arranged glass tube or coil with a larger surface area.
    • Cooling Effect: As the vapors rise from the boiling flask, they come into contact with the cold surface of the vertical condenser, causing them to condense and collect in a separate receiving flask. The vertical orientation allows efficient cooling and condensation of the vapors due to the longer path they have to travel.

    Horizontal Condenser:

    • Orientation: A horizontal condenser is positioned horizontally, extending out to the side of the rotary evaporator.
    • Design: It typically consists of a glass tube or coil arranged in a horizontal configuration.
    • Cooling Effect: The vapors generated in the boiling flask are directed through the horizontal condenser. As the vapors flow along the length of the condenser, they come into contact with the cool surface, which promotes condensation. The condensed liquid is then collected in a separate receiving flask. The horizontal design allows for efficient cooling while providing easier access for maintenance and adjustments.
