03 Aug 2011 BFi OPTiLAS, pan-european partner of Ocean Optics, is proud to announce that, expanding the potential applications for its oxygen and pH sensing patches, Ocean Optics has obtained United States Pharmacopeia (USP) Class VI certification for these products. The company’s HIOXY coating for RedEye Oxygen patches and Sol-gel coating for pH applications have successfully met the stringent testing criteria required for this certification.
BFi OPTiLAS – Ocean Optics’ optical O2 and pH sensors are designed for accurate, real-time, in situ measurements in packaging and other enclosed containers. The proprietary sensor coating materials do not consume the sample and can be applied to substrates such as probes, self-adhesive acrylic patches (the format tested for USP Class VI) and microtiter wells. Coating options are available for general lab use, high-sensitivity applications and hydrocarbon-rich environments. Depending on the application, oxygen presence or pH can be visually determined by colour change with a handheld LED, or a fluorometer can be used to make exact measurements.
The USP is a non-governmental standards setting organisation. Class VI is its most stringent testing protocol for classification of plastics used in medicines and other health care technologies. With USP Class VI certification, the biocompatibility, toxicity and extractable of sensor coatings are assured to be compatible with biological and pharmaceutical processes and implantable devices. Testing and certification were provided by NAMSA (Northwood, Ohio).
