This OEM compact pump module (MSP1-D1) is designed to feature precision liquid handling. It is capable of delivering accurate liquid with flow rates ranging from 0.5 - 150 mL/min or a desired dose volume when using a compatible syringe with an appropriate volume from 0.5 - 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.
