Valves are essential components in bioprocessing systems, providing precision fluid control across a wide range of sterile applications, including bioreactors, filtration setups, buffer preparation units, and fluid transfer manifolds. These components play a critical role in directing, regulating, and isolating process fluids in both stainless steel and single-use systems, ensuring aseptic processing, operational safety, and process consistency in biopharmaceutical manufacturing, vaccine production, cell therapy, and industrial biotechnology environments.
Valves used in life sciences are engineered for high sterility, cleanability, and chemical resistance, and are available in several formats including diaphragm valves, pinch valves, ball valves, butterfly valves, and check valves. Diaphragm valves are particularly common in bioprocessing due to their hygienic design and minimal dead volume, making them ideal for media control, CIP/SIP processes, and batch isolation. Pinch valves, on the other hand, are widely used in single-use systems, as they can control flow by compressing flexible tubing without direct fluid contact—preserving sterility and simplifying integration.
Valves are made from FDA- and USP Class VI-compliant materials such as stainless steel, polypropylene, PVDF, and EPDM or silicone elastomers. They are compatible with a wide range of pressures, temperatures, and flow rates and are designed for integration into automated control systems, enabling real-time process adjustments via PAT tools and PLC platforms.
In upstream bioprocessing, valves regulate nutrient feeds, gas inputs, and media transfers. Downstream, they control flow during chromatography, filtration, or formulation. Many valves are offered as single-use, pre-sterilized assemblies for fast deployment in cleanroom settings, eliminating cleaning validation and reducing turnaround times.
At Wasteless Bio, we offer surplus and high-quality valves from trusted manufacturers. Each listing includes detailed specifications such as valve type, connection style, material compatibility, actuation method, and pressure/temperature ratings. By sourcing valves through Wasteless Bio, laboratories and manufacturers gain access to cost-effective, precision fluid control solutions while advancing sustainability through equipment reuse in modern bioprocessing operations.
