intuitive touchscreen works even wearing gloves

Set up is a breeze

Intuitive touch screen interface, even wearing gloves

  • Easy to set up and program
  • 7" capacitive TFT/RGB touch screen with a clear, wide viewing angle
  • Adjust parameters with a simple touch-even with gloves on
  • Operational modes include continuous run, volume dispense, and time dispense
  • Batch control and interval/off time in Volume and Time modes
  • Antidrip and speed ramping available in Volume mode-ensure accuracy and minimize sample loss
  • Easily save and recall up to 50 commonly used protocols, each with a unique name
  • Know when you hit your mark-graphical indicator lets you know when loaded tubing is optimally calibrated

MasterSense monitors your media so you don't have to
