Specifications Handix Scientific Circles white Aerosol Devices Spot Sampler Liquid Sampling Module Swab Sampling Method
Optional Liquid Sampling Kit

- Deposits directly onto swabs for concentrated, easy to transfer sample
- Sample directly onto stabilizer (patent pending) for instant DNA/RNA preservation
- Ability to adjust sampling time on each swab from 1 minute to 24 hours

The BioSpot-GEM sampler includes a starter sample kit for immediate use (8 samples).
An impaction well can be added into the sampling column to allow collection to be compatible with methods such as spectroscopy and chromatography.

The BioSpot-GEM sampler includes one impaction well with the base unit.
- Liquid sampling is preferred method for viable capture of bioaerosol
- Particle collection into almost any liquid with collection volume from 300uL to 700uL
- Polycarbonate vials are available in ported and non-ported configurations

Handix Scientific Circles white The BioSpot-GEM uses a patented water condensation growth tube (CGT) to encapsulate airborne particles into liquid water droplets and gently deposit the droplets onto the surface of your choice. This technique substantially improves the efficiency and quality of collection of bioaerosols (<10nm to 10um), sampling directly onto a sterile stabilized swab or directly into liquid.

Whereas other techniques suffer from desiccation, mechanical stress, thermal stress, and re-aerosolization, the BioSpot-GEM sampler is efficient in collecting particles in public settings without distraction. Additionally, the water condensation growth tube technique has been published in many studies specifically searching for viable capture of bioaerosols.
