AT709 Dry microbial penetration tester Used to determine the resistance of materials to bacterial penetration on dry particles in the size range of human dander.
Numerous examples show that bacteria can penetrate shielding materials along with dry organic or inorganic particles, such as bacterial-carrying dander through surgical or clean clothing, and bacteria-carrying particles through packaging materials during storage.
