BioSpot-VITA

Series 308 Bioaerosol Sampler

Purpose

The BioSpot-VITA bioaerosol sampler uses water condensation capture for highly efficient, gentle collection of bioaerosols. Viable airborne disease capture is made more feasible in ambient environments from a lighter, more portable chassis while still maintaining higher sample flow rate.

Applications:

Viable capture of bioaerosol
Airborne disease transmission
Environmental microbiome
Infectious disease surveillance
Biocontamination monitoring in pharmaceutical manufacturing
Defense/Homeland Security bio-surveillance
Non-invasive characterization of particles from exhaled breath

Features

Specifications

Cleanable, rugged, and prepared for most environments, while being 41% lighter and 33% smaller than the existing BioSpot-VIVAS model

High efficiency collection of viruses, bacteria, fungal spores, toxins, proteins, allergens, and other aerosol

Gentle impaction into liquid and minimal heating of airflow maintains microorganism viability upon capture

How does it work?

The BioSpot-VITA bioaerosol sampler uses a patented, three-stage “moderated” condensational system to enlarge aerosol particles and then gently deposit them by inertial impaction. The initial cold “conditioner” establishes a controlled vapor saturated aerosol stream largely independent of the incoming sample flow conditions.

The warm walls of the “initiator” provide a region high of partial pressure of water vapor. Supersaturation occurs in the second region as a result of the difference in the diffusive rates of water vapor and heat transport.

The final cool “moderator” region allows continued droplet growth while reducing the flow temperature and water vapor content. The sampler deposits the droplets into a 2mL, 35mm diameter petri dish, cooled to a temperature convenient to the user.
