What is a Single Use Assembly / Bag Assembly in Bioprocessing?

A single use assembly is a combination of different components (ie tubing, single-use bags, fittings) which are assembled together based on a customer’s requirements. Single use assemblies are widely used in biopharmaceutical manufacturing, especially for processes that involve fluid transfer, mixing, filtration, containment and final fill.
