Description
The binary solvent manager is a high-pressure pump that moves solvent through the system. It provides steady (pulse-free) solvent flow at analytical flow rates. The binary solvent manager delivers solvent at flow rates of 1 mL/min at 103,421 kPa (1034 bar, 15,000 psi) and up to 2 mL/min at reduced pressures to 62,053 kPa (621 bar, 9000 psi). The binary solvent manager can pump two solvents simultaneously.
