Precision dispense piston pump is a type of small volume precision syringe pump with the flexible control options of the encoder, drier, solenoid valve, it is mostly equipped in medical analysis systems for delivering fluids in microliters or milliliters with very high precision, wetted materials are corrosion resisting and biocompatible for most chemicals or solvents, small footprints and high-cost performance make it a very special choice for medical or lab systems.
