To meet stringent bioburden and endotoxin limits demanded by critical medical device applications, New England Tubing Technologies utilizes dedicated reverse osmosis (RO) purified water throughout our manufacturing process.
A reverse osmosis system uses a semi-permeable membrane that allows the passage of water molecules, but not most of the dissolved salts, organics, bacteria, and pyrogens. However, the water must be “pushed” through the RO membrane by applying pressure greater than the naturally occurring osmotic pressure. When pressure is applied to the concentrated solution, the water molecules are forced through the semi-permeable membrane while the contaminants are not allowed through.
By actively controlling upstream water purity we mitigate microbial and pyrogenic contamination at the source. This ensures your custom extrusion and components consistently satisfy downstream biocompatibility.
