Single Pump
Pulseless flow
Reciprocating noise is minimized by using specially designed dual plungers connected in series and adopting the newly developed internal pressure damper and check valves. The discharge volume is 18.84 µL/rev. Pulseless flow is achieved by controlling the high density pulse step motor (flow rate range: 1-3000µL/min). Precise gradient curves are drawn even at a low flow rate.
High-precision control
The internal pressure damper makes a pulseless flow (flow rate range: 1-3000µL/min). Accurate gradient curves are attained by the pump system designed for semi-micro flows.
Easy operation by keys on the control panel
Besides PC-controlling, the pump can be operated via the ten-key control pad. Up to 50 steps can be set for flow programming (1-µL/min increments).
Metal-free pump head
The pump heads are made of polyetheretherketone (PEEK) resin. The use of PEEK avoids contamination of metal impurities, which may influence some physiologically active samples.
Software
The pump can be fully controlled by several different types of PC-based software (S-MC, EZChrom Elite, XCalibur, and Analyst).
Automatic purge
Solvent replacement has been greatly improved by employing an automatic purge function, which was not included in the previous model (3001).
