Mildew and Antibacterial Testing

As living standards improve, consumers increasingly favor indoor materials and items with special functions such as purification, antibacterial, anti-mildew, and anti-algae properties. Thanks to the efforts of researchers and manufacturers, products like antibacterial coatings, anti-mildew wallpapers, antibacterial ceramics, and bacteriostatic water purifiers are becoming common in daily life. Consequently, the demands on the testing capabilities of professional microbiology laboratories have grown significantly.

Since 2004, our laboratory has been jointly accredited by the China National Accreditation Service for Conformity Assessment (CNAS) and the China Metrology Accreditation (CMA). We are one of the earliest laboratories in China dedicated to evaluating the antimicrobial performance of materials and a governing unit of the Zhongguancun Alliance of Advanced Antimicrobial Materials Industry (CIAA). Our core services include testing for antibacterial, anti-mildew, anti-algae, antiviral activity, strain identification, evaluation of microbial purification efficiency, in vitro cytotoxicity testing, and zebrafish testing.
