Connectors

Connectors are critical components in modern bioprocessing and cell culture systems, enabling secure, sterile, and efficient integration of tubing, manifolds, sampling ports, and fluid transfer assemblies. These small but vital parts are essential for maintaining closed, aseptic pathways in upstream and downstream operations, supporting applications such as media addition, harvest, sampling, buffer exchange, and product transfer. Used extensively in biopharmaceutical manufacturing, vaccine production, cell and gene therapy, and industrial biotechnology, high-quality connectors are key to ensuring fluid integrity, process sterility, and compliance with GMP and ISO standards. Connectors come in various formats—including luer locks, quick-connects, aseptic disconnects, genderless fittings, barbed connectors, and Tri-Clamp fittings—to accommodate a range of tubing types, flow rates, and system configurations. Materials such as polycarbonate, polypropylene, polyethylene, PVDF, and stainless steel are selected for their biocompatibility, chemical resistance, thermal stability, and compatibility with gamma irradiation or autoclaving. In single-use bioprocessing systems, sterile connectors allow for closed system transfers, minimizing contamination risks during batch processing or scale-up. Many models are pre-sterilized and ready-to-use, and are designed to be welded, clamped, or clicked into place without compromising sterility. Some feature genderless designs for simplified connections and reduced inventory complexity, while others include built-in caps or seals for safe fluid disconnection. Whether used in perfusion systems, sampling workflows, TFF loops, or buffer prep, reliable connectors enhance process efficiency and flexibility. They also support modular system design, enabling labs to adapt quickly to changing production needs or integrate automation. At Wasteless Bio, we offer a wide selection of surplus and new sterile connectors from trusted manufacturers. Each listing includes key specifications such as material type, tubing compatibility, pressure rating, connection style, and sterility assurance method. By sourcing connectors through Wasteless Bio, bioprocessing facilities can reduce equipment costs, ensure aseptic processing, and promote sustainable, closed-system manufacturing through reusable and responsibly sourced components.
