Contec introduces Critical Site Wipes, made of polyester and containing 70% USP grade isopropanol and 30% USP grade purified water. The low linting, nonwoven, pre-saturated wipes are suitable for ISO Class 5 environments. Manufactured in Contec’s ISO-registered facility and validated sterile per the Association for the Advancement of Medical Instrumentation, these 4x4 inch wipes create a repeatable, consistent technique with a one-step process that can be used in place of sterile, individually wrapped alcohol prep wipes. The low profile, resealable, cleanroom-compatible packaging provides quick access and easy closure.
