These advanced microprocessor-controlled syringe pumps are designed especially for low, pulse-free flow rates. All pumps have a simple menu-driven setup for preset rate and volume control plus automatic shutoff, with the last settings stored in memory. Dispense volume is tracked and displayed continuously. When the preset volume has been dispensed, the pump shuts off automatically. Infusion pumps in the KDS200 series have built-in RS232 and TTL interfaces. Infusion/withdrawal models feature independent rate and volume settings for both infusion and withdrawal plus the selection of five different modes of operation. Programmable models can control the pump from seconds to days, change flow rates, pause, ramp rates up or down automatically, control outputs and respond to external TTL signals. Warranty: 1 year.
