BioSim test particles offer safe alternative to live pathogens and surrogate organisms, allowing for on-site simulation testing. Microscopic carrier beads with chemically attached DNA fragments mimic an actual organism when dispensed, collected, and analyzed, but are not harmful and will not cause disease. No personal safety precautions are needed for use. Dispenser holds 30 to 35 sprays.
