Waters Acquity Binary Solvent Manager

The Waters Acquity UPLC Binary Solvent Manager delivers solvent compositions for binary gradient methods at flow rates of 0.01 to 2.0 mL per minute.  The binary solvent manager's two pump channels permit quick solvent changeovers at a flow rate of 4.0 mL per minute. Low-volume degasser channels (480 µL internal volume), automated solvent-selection valves, and an automated vent valve make the quick changeovers possible.  The Solvents Tray accommodates up to four chromatographic solvents, two Sample Manager wash solvents and one Binary Solvent Manager Seal wash solvent


  • In-line filters upstream of a primary check valve
  • Waters Intelligent Intake Valve
  • Automated priming functions
  • Daily system-setup routines.
