OEM Syringe Pumps for Automated Liquid Handling

FOREACH OEM syringe pumps integrate glass-syringe metering with solenoid or rotary valves for reagent dispensing, sample dilution and liquid transfer in automated analytical instruments. The range includes HMD syringe pumps with solenoid valves and HLD syringe pumps with rotary valves, with 30 mm and 60 mm stroke options. Metering-channel counts, valve configurations and fluid connections can be customized for IVD analyzers, laboratory instruments and automated liquid handling systems.

Syringe pump selection should consider the required dispense volume, accuracy and repeatability, together with the number of metering channels, fluid paths and dispensing cycle time. Wetted-material compatibility, installation space and communication interfaces should also be evaluated. Metering channels refer to the syringe-metering units, while valve configurations determine how fluid paths are switched; each should be selected to suit the dispensing and fluid-routing requirements. RS-232, RS-485 and CAN communication options support instrument-controlled aspiration, dispensing and valve switching.

The HMD series uses solenoid valves to switch fluid paths and offers 30 mm and 60 mm stroke options. Single-channel and 2-, 3-, 4-, 6- and 8-channel syringe pump configurations support reagent dispensing, sample dilution and multichannel liquid dispensing. Solenoid-valve configurations and fluid connections can be customized to suit the required fluid circuit. The HLD series uses rotary valves to switch fluid paths, with 30 mm and 60 mm stroke options and customizable valve configurations, including 3-way, 5-way and 9-way rotary valves. These valves connect reagents, diluents, wash liquids and delivery lines for sequential aspiration and metered dispensing.
