Supelco Mobile Phase Degassing System

  • 4 Channel
  • 0-5 ml/min Flow Range
  • Validation output satisfies system compliance
  • Smart sensor detects leaks and communicates with vacuum pump
  • LED indicates degassing status
  • Unprecedented 4 year warranty

The Supelco Mobile Phase Degassing system with its smart sensor not only detects and alerts you to leaks, it also communicates with the vacuum pump. If a change in vacuum is detected due to mobile phase flow rate changes, the pump can compensate by changing its speed. The validation output records vacuum level to satisfy system compliance and validation requirements. The degassing system has a Teflon® AF membrane, with NO-OX™ fittings and tubing.
