Pure-Fit Sterile Connectors

Pure-Fit® SC is connective technology that makes it possible to create true sterile connections anywhere – even outside the clean room environment. It incorporates exclusive Pure-Fit® SIB® (smooth inner bore) technology, which provides a seamless transition between tubings and fittings in order to maintain complete fluid integrity. The silicone valve design at the heart of Pure-Fit® SC allows for easy assembly and leaves no gaps or residue, eliminating problems associated with other systems. The locking mechanism virtually eliminates the possibility of operator error, and also simplifies validation.
