The digital, stepper-motor controlled flow and non-circular gears of the 510 ensure smooth and precise flow regardless of back pressure,flow rate setting, or solvent compressibility. The optional extended flow pumpheads allow a larger sample volume and extend the flow range to 22.5 ml/min for semi-preparative applications.
This refurbished Waters 510 HPLC Pump is in great condition. It has been tested at SpectraLab Scientific.
A 90 day warranty is included.
