Rotary Evaporator POWERVAP

Rotary evaporator

POWERVAP® is a patented, fully automated pendulum system rotary evaporator.

The performance of the POWERVAP® is approx. factor 5, compared with a manual rotary evaporator system, which has the same size of rotating flask.

Technical Details of the POWERVAP®

  • Automatic filling and emptying of the rotating flask (patented).
  • Automatic emptying of the distillate chamber.
  • Generation of a desired product concentration.
  • Floating rotating flask, which contents is controlled by means of an inclinometer (patented).
  • The floating rotating flask reduces mechanical stresses, to achieve by constant tightness, a powerful distillation, even under permanent operation.


  • Precise control of the distillation process. Temperature, vacuum and other process parameters are also controlled, to handle foaming products.
  • Computer controlled reflux.
  • Unattended, safe and consistent operation.

Rotating flask

  • 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.
  • Hexagonal implosion protection system for the condenser, made of transparent polycarbonate.
Rotationsverdampfer POWERVAP

Ex-proof powervap-system


  • Excellent suitable for recovery of solvents.
  • Problem-free distillation of high boiling solvents.
  • Distillation of large amounts of solvent.
  • Concentration of extracts.
  • Concentration of fractions coming from HPLC.
