Research syringe pump EVO3

for biomedical researchchromatographylaboratory

Overview
The EVO3 is a programmable, maintenance-free syringe pump designed for precise liquid metering in laboratory and analytical environments. It features a 30 mm stroke driven by a stepper motor and precision lead screw and is available in two mechanical resolutions (3K, 24K). The unit can operate as a standalone controller or be integrated into complex systems.
