Powder Dropper

This device releases micron-sized dust particles at a controlled rate through an aperture in a vibrating crystal. The amount of dust released ranges from a few particles per second up to the choking point of the closed aperture. Our present crystal will pass ~ 5 million particles per second assuming particle diameter of 50 microns. The powder is released by vibrating a piezo crystal at the bottom of a reservoir. The amount of powder or dust that is released is controlled by adjusting the amplitude and frequency of the vibration.
