This HPLC pump is gradient designed for pumping up to 3 solvents in various compositions at precisely controlled flow rates and pressures. This unit works in conjunction with SP8700RX HPLC Solvent Module (not included).
You can progam the time, the percentages for your A, B & C samples, flow rate, pressure, you can run the test mode, run your gradients as well as edit and store the files. All this from the clearly labeled touch pad.
The back has a socket for a Labnet plug-in and terminals for 5V AT 20 mA, Run/Grad, Pump Stop & Ground. There is also a cable which has had the connector removed, but presumably went to the solvent module.
Power: 120/240 VAC, 46-63 Hz, 3/1.5 Amps.
