50 Liter Rotary Evaporator EX


50L evaporation flask, 20L receiving flask, 7.5kW heating bath, max temperature 180C, 380V 3-phase (customizable)

These rotary evaporators feature a simple and reliable modular design, making it one of the most reliable rotary evaporators in industry. Their open and straight-forward structure also makes them extremely easy to maintain and repair. These evaporators are designed with various safety features (dry-heating shut off, over temperature protection, soft start of rotation, over-current protection) to provide maximized protection during operation.

This is the upgraded (explosion proof) model, which is rated for Exd IIB T4 (equivalent to Class I, Division 1, Group C T4). For extreme conditions, we are able to customize the system to air-driven motor and steam-heated bath, which totally eliminate risks from electrical components.

  • All the wetted components are made of high-quality+ boro 3.3 glass and PTFE, for excellent corrosion resistance.
  • High precision vacuum seal and vapor tube design leads to ultimate vacuum performance (1 mbar end vacuum, < 1 mbar/min vacuum leakage).
  • Modular and straight-forward structure for extremely easy maintenance.
  • High torque motor, high precision worm-gear gearbox, and hand lift components for years of quiet and reliable operations.
  • Easy and straightforward operation of speed and temperature controller.
  • The heavy-duty SS304 support frame and epoxy-coated water/bath enclosure guarantee vibration-free operation.
  • 2-stage triple-coil condenser design with an extra large cooling surface for outstanding cooling efficiency.
  • 1-way check valve automatically turns off when draining the receiving flask. The pressure inside evaporator won’t be changed during draining.
  • The VFD speed controller keeps the motor’s torque at its maximum even during low-speed range.
  • The temperature controller comes with a built-in over-temp monitor, which shuts off heating when bath temperature is 15C higher than set value.
  • Various options and accessories are available (vacuum pump, chiller, vacuum controller, cold trap, etc)
