Road Map to Implementation of Single-Use Systems

        The Bio-Process Systems Alliance (BPSA) is an organization of equipment suppliers, service providers, and users in the biopharmaceutical industry whose shared mission is to facilitate implementation of single-use technologies in biomanufacturing processes. A key focus of BPSA’s core activities is to educate users and develop guides that help safeguard the quality of drugs and therapies produced with single-use process technologies. As an extension of its technical guides and white papers, BPSA realized the importance of developing…

Polymers and Additives Used in Fabrication of Disposable Bioprocess Equipment

The materials used to fabricate single-use processing equipment for biopharmaceutical manufacturing are usually polymers, such as plastic or elastomers (rubber), rather than the traditional metal or glass. Polymers offer more versatility because they are light-weight, flexible, and much more durable than their traditional counterparts. Plastic and rubber are also disposable, so issues associated with cleaning and its validation can be avoided. Additives can also be incorporated into polymers to give them clarity rivaling that of glass or to add color…

Effect of Sterilization on the Mechanical Properties of Silicone Rubbers

    Silicone rubber is widely used in the pharmaceutical industry, where sterilizability is an essential requirement for all fluid transfer equipment. Pharmaceutical products are sterilized frequently and repeatedly by high-level energy and/or chemical vapor to eliminate bacterial surface contamination. Such treatments may also affect the molecular structure of silicone rubbers, causing changes in their physical properties and performance. Several studies on this topic have been reported; until now, however, no systematic investigation has been performed on the effect of…
