In this letter we describe a simple device built from a laboratory ultrasonic generator and a glass capillary that can 'jet' samples of dry powder of mass down to 0.05 mg. Placed over a three-axis table, it provides an ink-jet printer for powders. It can be used for any application requiring precise placement of powder samples but our primary interest is its use in so-called second generation solid...
This communication describes a method for both on/off and flow rate control of dry powders in open capillaries using acoustic vibration. In a glass capillary attached to an electromagnetic transducer, the wave characteristics of the forced vibration control both flow rate and switching of powder flow. The valve is free from relative movement of parts that may wear or seize in the presence of fine...
