Operating Principle of PI Nanodispensers
This video shows the operating principle of Physik Instrumente (PI)’s Nanodispenser. The drives used for nanoliter or picoliter dosing devices must function with high-operating frequencies of up to several kHz and at the same time create the kinetic energy needed to produce minute droplets without subsequent nebulization, dripping, or satellite formation.
Piezo actuators can switch valves directly. They can also work against a closing spring or a flexible tube for volume displacement.
