Vacuum for Rotary Evaporators

Requirements:

  • chemical resistance
  • tolerance to condensates
  • precise vacuum control

Notices for Pumpchoosing:

Vacuum at the push of a button:
Find vacuum level, follow vapor pressure, control with precision, all fully automatically

Specific advantages:

  • always the correct vacuum level, irrespective of application size and volume of vapour
  • fully automatic adaptation of the vacuum to actual process parameters (distillation, drying, etc.)
  • shortened process times with high evaporation rate

This and more is offered by the VARIO Pumping Units

Ultimate vacuum 7 mbar:

 

 

 For low-boiling-point solvents, e.g. solvents which formerly could be evaporated by “water-jet vacuum”, e.g. H2O at 20 °C bath temperature
Ultimate vacuum down to 1.5 mbar: For high-boiling-point solvents
Ultimate vacuum 0.6 mbar: For high-boiling-point solvents at low temperature, e.g. DMF for T ≥ 20 °C / DMSO for T ≥ 40 °C
Ultimate vacuum 7 mbar: For low-boiling-point solvents, e.g. solvents which formerly could be evaporated by “water-jet vacuum”, e.g. H2O at 20 °C bath temperature Ultimate vacuum down to 1,5 mbar: For high-boiling-point solvents Ultimate vacuum 0.6 mbar: For high-boiling-point solvents at low temperature, e.g. DMF for T ≥ 20 °C / DMSO for T ≥ 40 °C
