HPLC-GPC-Pumps

HPLC - Pump SDS 9414I

The HPLC-Pump SDS 9414I is a dual plunger solvent delivery system. The mechanical design includes short plunger stroke technology with only two check valves. This results in low pulsation, typically observed with dual plunger pumps.

The microprocessor controlled speed regulation results in a very accurate constant drive of the motor. Through a mathprogram the processor regulates the pressure compressibility of the eluent continously.
HPLC-Pump SDS 9414I
The pump is equipped with an automatic control system which can be programmed in two different working modes (constant flow rate or constant pressure). Furthermore the pump is equipped with an analog and serial interface through which the pump can be controlled externally.
