Contec announces Critical Site Wipes, polyester 4-in x 4-in wipes that contain 70% USP-grade isopropanol and 30% USP-grade purified water. The low-linting, nonwoven 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 presaturated wipes create a repeatable, consistent technique and provide a one-step process that can be used in place of sterile, individually wrapped alcohol preparation wipes, which can be sources of contamination. The low-profile, resealable, cleanroom-compatible packaging allows for quick access and easy closure.
