Ketron™ LSG FG PEEK (Life Science Grade & Food Grade) stock shapes are made from unfilled PEEK resin that is pre-assessed for biocompatibility. The stock shapes are also pre-assessed for biocompatibility for up to 24 hours contact with body and tissue according to USP VI and ISO 10993. Some color variations are also pre-assessed for use in wetted contact applications in bioprocessing. Standard food approvals include the FDA 21 CFR § 177.2415, while this specific FG type has the EU 10/2011 Food Grade as an extra feature.
Ketron™ LSG FG PEEK (Life Science Grade) shapes exhibit high stiffness and mechanical strength. The components are also sterilizable by means of steam (autoclave), dry heat, EtO (ethylene xxide), plasma and gamma and X-ray irradiation. The additional food grade compliance (based on food-related migration tests) makes this material an excellent candidate for applications in the bioprocessing fields, such as manifolds, valves, connectors, lids and adapters.
