VACUUBRAND738400ca. 444 mmca. 243 mmca. 20.6 kg

This VARIO® pumping unit provides precise vacuum control by adjusting the diaphragm pump´s motor speed. It features fully automatic evaporation control at the push of a button. The PC 3003 VARIO provides an excellent ultimate vacuum and is therefore the best solution for evaporations of high boiling solvents even at low temperatures. It combines extraordinary performance with a compact design and very low noise. The separator at the inlet, made of glass with protective coating, retains particles and liquid droplets to protect pump performance. The exhaust vapor condenser at the outlet enables near-100-percent solvent recovery. The on-demand motor speed control results in unsurpassed lifetimes for service parts, such as diaphragms.

Performance features

  • automatic optimization of vacuum levels throughout the process for high process reliability and unattended operation
  • short process times due to powerful pump and zero-fluctuation (hysteresis-free) vacuum control
  • ideal for high-boiling solvents and evaporation at low temperatures
  • easily operated CVC 3000 vacuum controller with clear text menus and integrated venting valve
  • excellent environmental friendliness due to efficient solvent recovery
