RADIX OPA is a high level disinfectant for reprocessing heat sensitive reusable semi-critical medical devices such as endoscopes, for which sterilization is not feasible. OPA is intended for use in manual (bucket and tray) systems made from polypropylene, acrylonitrile-butadiene-styrene (ABS), polyethylene, glass-lled polypropylene and/or polycarbonate plastics. It may also be used in automated endoscope reprocessors. Activation is not required.
