      Detailed Specs

      The BioSpot-VIVAS sampler performs much like the human lung, providing high-efficiency, gentle collection into liquid through condensation-enhanced inertial deposition. A laminar-flow condensation growth tube (CGT) encapsulates airborne particles into liquid droplets and gently deposits the droplets onto a liquid surface. The air sample flow is 8 L/min, approximating the average rate at which a person breathes. Particles from this flow are deposited into ~2mL of water, buffer, nutrient broth solution or genomic preservative (patent pending). Bioaerosols, including viable viruses, bacteria, fungal spores, toxins, and exhaled proteins are collected with high efficiency independent of their size, shape, or hydrophobicity. The high-fidelity, concentrated samples are ready for lab analysis.

      A New Sampling Approach
      A laminar-flow water condensation particle growth technique substantially improves the collection of bioaerosols (<10nm to 10µm) sampling directly into a liquid medium.
