Scope of Application

【Operating Instructions】

Protective clothing materials are expected to come into contact with aerosols generated by contaminated liquids. Therefore, it is necessary to determine their resistance to the penetration of contaminated liquid aerosols to characterize the protective effect of the material against contaminated liquids.The Contaminated Liquid Aerosol Penetration Tester is used to test the microbial barrier properties of medical protective clothing or sterile medical device packaging materials under conditions specified in standard tests.The product consists of: a test chamber, a biological safety cabinet, a microbial aerosol generator, a sample filtration assembly, and a vacuum control system. The product features simple operation and intelligent control.
