Syringe Pump SY03B in DK Series

SY-03B Dk series product is a kind of micro-syringe pump with multiple syringes working in parallel in high precision developed by Runze Fluid. Use a stepper motor to drive the syringe and the valve to aspirate and dispense quantitative liquid. The syringe is replaceable. It is a fully programmable pump module with the open framework, which handling fluids from microliters to milliliters with extraordinary accuracy and precision. It can be controlled by an external computer or microprocessor, and with functions in automatic pipetting, dilution and dispensing.
