Rotary evaporator
POWERVAP®

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.

Controller

• 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 dampening 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.

POWERVAP®- Applications:

• 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.
