Reprocessing flexible fiber endoscopes in-use studies supports the effectiveness of Micro-Cide 28 HLD in actual use. (ASTM 1518-94 protocol). In addition, a simulated use-test was conducted to support the contact condition for high-level disinfection of endoscopes at 25°C at 25 minutes. The results demonstrate the effectiveness of Micro-Cide 28 HLD to kill M.Terrae dried on flexible fiber endoscopes.

(Studies were performed after 28 days of simulated re-use following prescribed AOAC testing methods).
