ULTRASONIC GENERATOR

ULTRASONIC GENERATOR FOR AEROSOL PRODUCTION


Principle :

If an intense beam of ultra sounds is focused near the free surface of a liquid, a fountain is formed which emits an aerosol. The sizes of droplets in his aerosol are uniform, depending on liquid charateristics and ultrasound frequency.

Application :

1. Medical
An effective way to deliver medication via the lungs.

2. Industrial

When a product can be prepared in liquid form production of aerosol is a usefull way to divide a product into very small fractions of uniform size. RBI aerosol generators are used in many applications, for example

- thin layer realisation (optics and micro electronics)
- thin powder production (chemistry)
- chemical reactions between liquid and gas

3. Research laboratories

These aerosols may be used as tracers in turbulent diffusion simulations.

Actual sizes of droplets may be measured by the RBI light scattering granulmeter.
