A Study of Liquid Dispensing Head Using Fluidic Inertia

概要

A nanoliter dispensing head based on a novel principle has been proposed. In this dispensing head, a piezo ceramics transducer moves a glass capillary holding liquid in the direction of dispensation. As a result of this movement, pressure waves are generated in the capillary, resulting in the dispensing of a small droplet from the nozzle. In order to understand the basic performance of this head, we have studied the effect of voltage waveform application to the piezo ceramics transducer on droplet formation. We have also studied the effect of sample liquid volume in the capillary on droplet formation and the effect of sample liquid viscosity on droplet properties. Under typical dispensing conditions, the volume of a drop was 1nl and the coefficient of variation was 5%. [DOI: 10.1143/JJAP.41.3442]
