Millipore Lynx® ST Aseptic Connector

Overview

The Millipore Lynx® ST Aseptic Connector is an engineered single-use component designed to establish rapid, reliable, and fully validated sterile fluid path connections between stainless-steel process equipment (e.g., bioreactors, pumps, chromatography skids) and disposable fluidic systems—including tubing assemblies, storage bags, and filtration cassettes. It operates on the principle of mechanical compression-sealing combined with pre-sterilized, gamma-irradiated polymer interfaces, eliminating the need for steam-in-place (SIP) or clean-in-place (CIP) cycles during system setup. Unlike traditional aseptic connection methods relying on operator-dependent manual techniques—such as flame-sealing or open-tubing splicing—the Lynx® ST delivers consistent, repeatable sterility assurance by physically isolating the internal fluid pathway until engagement, thereby preventing environmental contamination and minimizing human intervention error. Its design complies with core requirements for closed-system bioprocessing under current Good Manufacturing Practice (cGMP) guidelines and supports risk-based quality management frameworks aligned with ICH Q5A(R2), ISO 13408-1, and ASTM F1640 standards for sterile barrier integrity.

Key Features

• Gamma-irradiated (25–45 kGy) and certified sterile upon delivery—no additional sterilization required prior to use
• Robust polymeric housing with integrated O-ring seals and precision-machined stainless-steel ferrules for high-integrity mechanical coupling
• Available in multiple configurations: straight, elbow, and Y-branch variants; compatible with standard sanitary fittings (e.g., Tri-Clamp® 1.5″, 2″, 3″, and DIN 11851)
• Validated for pressure ratings up to 3 bar (43.5 psi) and temperatures ranging from –20 °C to +60 °C during operation
• Leak-tested per ASTM F2096 bubble emission test and verified for microbial retention using Brevundimonas diminuta challenge (≥10⁷ CFU/cm²) per ISO 11140-4
• Designed for single-use only—eliminates cross-contamination risk and removes validation burden associated with reprocessing

Sample Compatibility & Compliance

The Lynx® ST connector is compatible with a broad range of single-use bioprocess components, including polyethylene (PE), ethylene vinyl acetate (EVA), and thermoplastic polyurethane (TPU) tubing; gamma-stable polyolefin storage bags (e.g., Mobius® C-Flex®, Pure-Flex®); and low-protein-binding filters. It meets material biocompatibility requirements per USP and cytotoxicity testing, and its extractables profile has been characterized per USP and . The device is manufactured under an ISO 13485-certified quality management system and supports regulatory submissions requiring documented traceability, lot-specific sterility certificates, and endotoxin limits ≤0.25 EU/mL (LAL test, USP ). It is routinely deployed in processes subject to FDA 21 CFR Part 11-compliant electronic record environments when integrated with qualified data acquisition systems.

Software & Data Management

While the Lynx® ST connector itself is a passive hardware component, its integration into digitally enabled bioprocess workflows is supported through compatibility with industry-standard electronic batch records (EBRs) and manufacturing execution systems (MES). Each connector is supplied with a unique serialized label enabling traceability via barcode scanning into LIMS or MES platforms. Sterility certificates, gamma irradiation reports, and material compliance documentation are accessible through Millipore’s online product portal and can be automatically linked to batch records during system assembly. For customers implementing digital twin strategies, dimensional and material specifications are available in STEP and IGES formats for CAD-based process modeling and risk assessment (e.g., FMEA).

Applications

• Aseptic transfer of cell culture media, buffers, and harvest streams between stainless-steel vessels and single-use bioreactors
• In-line sampling for process analytical technology (PAT) monitoring without breaking system sterility
• Connection of downstream purification modules (e.g., TFF cassettes, chromatography columns) to upstream bioreactor outputs
• Closed-system filling of final drug substance into cryo-bags or formulation vessels
• Integration into continuous bioprocessing trains where uninterrupted fluid path integrity is critical

FAQ

Is the Lynx® ST connector suitable for high-shear or viscous fluid transfer?
Yes—its low-pressure-drop internal geometry and smooth bore surface minimize turbulence and shear stress, making it appropriate for sensitive monoclonal antibody (mAb) solutions and viral vector suspensions.
Can Lynx® ST connectors be used in GMP clinical manufacturing?
Yes—they are widely deployed in Phase I–III clinical supply chains and have supported multiple BLA submissions with documented validation packages.
What documentation is provided with each shipment?
Each lot includes a Certificate of Conformance, Gamma Irradiation Report, Sterility Test Report (per USP ), and Endotoxin Test Report (per USP ).
Are custom configurations or labeling options available?
Yes—Millipore offers OEM co-branding, custom port orientations, and integration-ready kits with pre-attached tubing and bag ports upon request.
How should unused connectors be stored?
Store unopened packages at 15–25 °C in dry, dark conditions; avoid exposure to UV light or ozone-generating equipment to preserve polymer integrity.
