Piezos Enable Faster Solution Switching

Wednesday, December 29th, 2010

Piezos are suitable for fast switching, as they offer electromagnetic quietness, good repeatability, high reliability and fast speeds. However, fast acceleration can mean recoil forces excite vibration in the pipette and both piezo and stepper actuators have suffered from these in the past, causing unwanted, repetitive solution switching for many milliseconds. Engineers ...
