The Thermo Finnigan Surveyor LC Pump Plus is a quaternary, low-pressure mixing pump with built-in solvent degassing and pulse dampening systems. The pumping system provides optimum performance in the lower flow rate ranges needed for mass spectrometry. You can run precise gradients from 25 to 2000 uL/min. An extremely low gradient delay volume of 80 uL ensures minimum system cycle times. The integral vacuum degasser offers superb solvent degassing efficiency with less than 500 uL of volume, and the pulse dampener produces stable flow rates with only 3 uL of delay volume.
