Manual Rotary Evaporators

Rotary Evaporator PILOTVAP®

The PILOTVAP® is a patented pendulum system rotary evaporator.


  • Excellent suitable for recovery of solvents
  • Problem-free distillation of high boiling solvents
  • Distillation of large amounts of solvent
  • Concentration of extracts
  • Drying of powders
  • Concentration of fractions coming from HPLC
  • We would be glad to develop with you customer specified solutions.


All PILOTVAP®-Systems can be modified to the fully automated rotary evaporator POWERVAP®.

Technical Details of the PILOTVAP®

Rotating flask

  • The floating rotating flask reduces mechanical stresses, to achieve constant tightness and a powerful distillation result,
    even under permanent operation (see pendelum system)
  • Hydraulic damping system for the rotating flask with drive system (patented), to increase the performance,
    when drying powders
  • Surface treated glass flanges for maximal vacuum stability

Sealing system

  • High performance sealing system
    – PTFE / glass
    – Service life approx. 20,000 hours of operation
    – Final vacuum better than 0.1 hPa (when empty)
    – 3 years warranty
  • Sealing system STACONSEAL, patented (option)
    – Final vacuum better than 0.01 hPa (when empty)
  • By means of the novel sealing system, a very good solvent recovery rate will be achieved

Protection Systems

  • Vapor temperature alarm, to automatically shut off the water bath
  • Implosion protection hood for the rotating flask, made of transparent polycarbonate
  • The pendulum system makes the rotating flask float in the water bath, to guarantee highest performance, easy handling and maximal reliability

Controller GUARD (standard)

  • Manual or automatic vacuum control
  • Control of the aerating valve (air- or nitrogen inlet)
  • Vapor temperature control
  • Speed control with slow acceleration mode
  • Control of the water bath temperature
Controller SCU (option)
  • Speed control with slow acceleration mode
  • Control of the water bath temperature (option)
  • Vapor temperature control (option)

Technical features of the process controller GUARD

  • Manual vacuum control with ACCEPT function to easily select the SET value
  • Automated vacuum control
  • Emergency SHUT OFF and aeration at overpressure (alarm)
  • Temperature control of heating bath
  • Vapor temperature control
  • Pulse aerating
  • Speed control with slow accelerating mode
  • Automated speed control (patented/option)
  • Torr/hPa (mbar) selector
  • RS232-interface
  • USB-interface (option)
  • Output for vacuum pump (solid state)
  • Coolant temperature indicator (option)
  • Capacitive keyboard – chemically resistant
  • Control of foam by pulse dosing (patented/option)
  • STACONSEAL sealing monitoring device for vacuum values better than 0.1 hPa – excellent for high boiling solvents and best product qualities (patented/option)
  • Customer specified solutions (option)
