Features

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

Concentrated samples into liquid for high sensitivity analysis, improving LOD/LOQ

High particle collection efficiency with no particle bounce, <10nm to 10um, >90% efficiency

Minimal heating of the airflow minimizes loss of volatile constituents and reduces thermal decomposition

User-controlled temperature of petri dish improves preservation of capture bioaerosol

Heavy-duty design is cleanable, rugged, and prepared for most environments

How does it work?

The BioSpot-VIVAS 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.
