Asepti-line™ PUPSIT Assembly

The V&W Biotech PUPSIT Assembly is a sterile, single-use fluid management assembly designed to support Pre-Use Post Sterilization Integrity Testing (PUPSIT) of sterilizing-grade membrane filters used in aseptic biopharmaceutical manufacturing processes. PUPSIT is a European regulatory requirement for sterile medicinal products. PUPSIT is a mandatory work step in final fill filtration (final filling) for biopharmaceutical manufacturers. PUPSIT measures the integrity of the sterilizing filter and all the components—filter housing, connections, and support structures—after installation and sterilization, but before the drug manufacturers use it. As part of a effective contamination control strategy in aseptic processing, PUPSIT is one way by which manufacturers help ensure the sterility of their aseptically-filled medicinal drug products. PUPSIT determines the integrity of the sterilizing-grade filter and assembly, including filter housing, support structure, and connections, after the assembly has been installed and sterilized but before it is used to filter product. PUPSIT provides assurance that a sterilizing-grade filter is intact and serves as a safeguard in the final filtration and filling stage of aseptic drug manufacturing. Regulatory standards continue to evolve, requiring more, integrity testing. Thus it becomes increasingly important that manufacturers understand the benefits of PUPSIT, as well as how product and process can both mitigate and contribute to contamination risk. Integrity testing remains crucial to delivering safe and effective drugs to patients, and biomanufacturers must balance evolving regulatory expectations and practical implementation challenges of PUPSIT.
