Product Introduction

SP4-E1 is a compact OEM pump module designed to handle precision liquid handling application. The pump could be mounted with 4 special designed glass syringes from 50ul to 5ml. And the four syringes will run synchronously. The pump is configured with 4 channel solenoid valves for the liquid passage control. It is controlled by an external controller or computer through RS485 or RS232 interface and automates pipetting, diluting and dispensing function.
Flow rates：0.0015ml/min-≤120ml/min
Max. Number of Channels：4
