Saint-Gobain's Marathon Diaphragms Achieve USP Class VI, Benefitting Medical Device Manufacturers
Saint-Gobain's Marathon diaphragms were recently certified as USP Class VI compliant, in which the plastic resin material passed Class VI certification for particular use in medical devices and expected to produce favorable biocompatibility results.
USP defines six plastics classes from I to VI, with VI being the strictest, and their class plastic tests are designed to assess the biological reactivity of various types of plastics materials in vivo. To meet the requirements for Class VI certification, which require the most extensive testing, a specific “in vitro” study (based on the USP General Chapter <87> biological reactivity test to determine potential cytotoxicity)
