We provide single-use molded assemblies that have ability to provide a consistent and repeatable solution. Because the components are molded from a single piece of material, there is no need for assembly or welding, reducing the risk of variability in the final product. This can improve process efficiency and product quality in biopharmaceutical manufacturing. The molding process involves shaping the polymer material into a specific shape or form, creating a single piece component that is both durable and flexible. The molded components are then assembled into a pre-sterilised assembly, providing a clean and sterile solution for bioprocessing applications.
