WEB EXCLUSIVE Two new antimicrobial PC grades from Bayer MaterialScience, Pittsburgh, use a silver-based inorganic additive to control growth of bacteria on the surface of medical devices. These developmental grades, Makrolon DP1-1868 and DP1-1869, have different levels of efficacy. Stain testing shows that bacteria on untreated PC grow unabated, while bacteria growth on the antimicrobial PC is virtually non-existent. Potential applications include IV access systems, urological devices, and housings for diagnostic and hospital equipment. (412) 777-2000 * www.bayermaterialsciencenafta.com
