Dynamic Aerosol and Bioaerosol Generation

Ultrasonic Nozzles for Bioaerosol Generation


Sono-Tek ultrasonic nozzles are often used in aerosol generation processes for early detection of harmful biological agents and environmental monitoring of pollutants. Standoff detection of bioaerosols provides important data for environmental monitoring and consequences of an actual agent release. By spraying dissolved agents in solution using an ultrasonic nozzle, simulations enable spectroscopic data collection to measure concentrations of biological toxins present in the air. These procedures are important for researchers and government agencies in ensuring early warning and rapid response to potential threats.

Aerosol generation using ultrasonic spray also enables evaluation of bioaerosol sensors or filtration devices used to rapidly identify/remove pathogenic agents including: spores, bacteria, viruses, and toxins.

Critical to this testing is the tight control of droplet size and the ability to vary droplet size based on nozzle frequency. To learn more about Sono-Tek ultrasonic nozzle drop sizes and drop distribution, go to http://www.sono-tek.com/drop-size-and-distribution/.

The frequency of the ultrasonic nozzle used and the concentration of the liquid being atomized determine the size of dry particles. Sono-Tek’s aerosol generation nozzle is specially designed with a unique liquid isolation channel that isolates the wetted path all the way to the nozzle tip, further optimizing drop distribution characteristics.

Flange designs are available for easy attachment to spray chambers.
