The Surveyor LC Pump Plus is a dual-piston, quaternary, low-pressure mixing pump with a built-in vacuum degasser and pulse dampener. The pumping system provides flow rates from 0.001 to 9.999 mL/min and can run precise gradients from 0.200 to 2.000 mL/min. The integral vacuum degasser offers efficient solvent degassing while requiring only 500 μL of volume, and the pulse dampener produces stable flow rates while adding only 400 μL of gradient delay volume to the system. The Surveyor LC Pump Plus is a module of the Surveyor HPLC.
