RP-TX peristaltic pump
RP-TX peristaltic pump size


Peristaltic pump based on the Ring Pump principle with stepper motor for dosing or pumping very small quantities of liquids. Due to the exchangable pump head, this pump offers a maximum flexibility.

Due to its small dimensions and flow rate, this pump is ideally suited for microfluidic applications.
