This OEM compact pump module is designed to feature precision liquid handling. It is capable of delivering accurate liquid with flow rates ranging from 2.5 µL/min to 1250 mL/min or a desired dose volume when using a compatible syringe with an appropriate volume from 50 µL to 5 mL. The pump module can be controlled by a standalone controller or a computer program communicating through an RS485 or RS232 interface. This OEM module is ideal for auto-pipetting, sample diluting or mixing, and/or sample dispensing in mass spectrometers, flow cytometers, and IVD instruments, etc.
