Another innovation from Across International and DigiVac:

Concerto: Automatic Vacuum Process Controller | Vacuum control and venting with the touch of a button or twist of a dial

  • Vent chambers with the touch of a button instead of pulling hoses or turning valves
  • Treat material in chamber more gently by implementing kinder ramp rate controls
  • Vacuum Controller with onboard ramp rate recipe control. Set up to 8 recipes based on time and pressure setpoints.
  • Dashboard pushbutton control for START, STOP functionality for each channel allows you to automatically vent or isolate your system with a push of a button

Silver Innovation Award Winner for Instrumentation at PittCon 2020!

The vacuum controller is particularly useful when you are looking to maintain pressure at a certain level as needed for botanical processing and rotary evaporation. Or you need to automate and simplify vacuum chamber pressure control.


  • Control up to 4 chambers with only 1 vacuum pump
  • Applications: rotary evaporators up to 100 Liters,  Falling Film Systems, vacuum chamber research, vacuum ovens/vacuum drying
  • Fine control of target vapor pressure for more precise compound separation through distillation using this state of the art pressure controller
  • Enables using reliable and long lasting rotary vane pumps & dry scroll pumps in applications where diaphragm
    pumps were previously required
  • Keeps vacuum pumps near their base pressure resulting in greater longevity


  • Largest flow paths available to insure maximum flow for faster evaporation
  • Maximize throughput and pump down speed and  with a 17.5 mm vacuum path to each hose barb


  • Automatic Vacuum Process Controller | precise automated control with programmable recipes and graphing of vacuum levels
  • Innovative valve control performs both proportional throttle and bleed vacuum control (vent to atmosphere)
  • The integrated bleed design allows you to quickly vent to atmosphere to stop bumping during processing
  • Numerical readings right on the LCD screen and one touch buttons: VENT, CLOSE (isolate, close all valves) and FULL VAC (fully opens the valve for vacuum pump and closes the vent valve)
