Bioaerosol Spray and Mist Bioaerosol Creation for Research
Sono-Tek ultrasonic mist platforms are designed for safe, controllable bioaerosol creation in contained research environments. A Bioaerosol Spray produced by ultrasonic atomization generates fine, uniform droplets with a narrow size distribution, supporting repeatable microbiology and aerobiology studies where aerosol particles must be consistent from run to run.
In published laboratory systems, Sono-Tek nozzles serve as the primary bioaerosol generation engine for creating realistic, dynamic aerosol test environments in indoor air and outdoor air simulation work.
Bioreactor Spray for Cell Culture and Aerosol Bioprocessing
Sono-Tek technology is also used as a Bioreactor Spray approach for aerosol-based cell culture and plant-root bioreactor research. Ultrasonic mist enables uniform delivery of nutrients or active solutions to substrates without flooding, helping maintain viability and supporting higher biomass yield in aerosol bioreactor concepts compared with conventional liquid-phase approaches.
Because the process is pressureless and low-velocity, researchers can generate mist bioaerosol conditions while maintaining stable environmental conditions such as relative humidity and air quality inside a chamber or reactor.
Controllable Bioaerosol Creation with Adjustable Particle Characteristics
A key advantage of Sono-Tek bioaerosol creation platforms is controllability. In published systems, ultrasonic atomizers allow independent adjustment of liquid delivery and formulation concentration, enabling precise control of aerosol output and particle size behavior without relying on compressed-air shear.
That control helps researchers tailor:
- Particle size and size distribution
- Aerosol particle concentration (quantification and repeatability)
- Droplet consistency for culturable microbes or non-biological bioaerosol particles
- Test scenarios for sampling/sampler validation and sensor evaluation
- Indoor air, outdoor air, and other environmental condition simulations
These strengths are why U.S. government and university laboratories continue to reference Sono-Tek systems in peer-reviewed bioaerosol, public health, and airborne-particle research.
Stable, Non-Clogging Mist Generation for Long Experiments
Sono-Tek ultrasonic nozzles are non-clogging and designed for extended operation with consistent aerosol output. This stability supports long-duration studies involving microorganisms, airborne bacteria, fungal spores, allergens, or other aerosolized test particles where maintaining repeatable conditions is essential for human health, infectious disease, and indoor environment research.
In 2013, a technical paper was published that referenced Sono-Tek’s equipment for bioaerosol applications.
