Functionality of the DLW Option

DLW Pumps
From the control point of view, the DLW pumps respond in the same manner
as the Fast Wash Station. The pumps are activated by Power-out Signals. The
electric current setting for the DLW is different; this means that the
corresponding Firmware Objects have to be loaded for the DLW wash station
type. See
further details.
The wetted parts in the pump are made of the following materials:
• Membrane: Kalrez (FFPM)
• Body, Valves: Ryton PPS
The pumps are self priming with a suction lift of up to 3 m water column.
DLW Actuator/Solenoid
The DLW Actuator/Solenoid has the function of separating and completely
shutting-off the lines in the direction of the syringe (sample loading) or the
wash solvent lines.
After opening the DLW Actuator/Solenoid for the wash solvent lines, the
desired wash solvent can be pumped into the system by activating the
corresponding DLW pump.

The wetted parts in the DLW Actuator Solenoid are made of the following
materials:
• Solenoid body: PEEK
• Seal material: FFKM (Simriz)
