Falcon Nylon Cell Strainer 40 um Individually Sealed Case of 50 Filters

Falcon® 40 µm Sterile Nylon Cell Strainers (352340) – Case of 50

The Falcon® 352340 Cell Strainer is a premium, research-grade laboratory consumable engineered to isolate clean single-cell suspensions from complex tissues, primary organ digests, or cellular aggregates. Injection-molded with a color-coded polypropylene housing, this device features a highly uniform **40 micrometer (µm) nylon mesh matrix** that provides reliable particle retention without cell shearing. Its unique structural frame matches standard 50 mL conical centrifuge tubes perfectly, enabling rapid, gravity-assisted or vacuum-accelerated filtration workflows. Supplied as a commercial facility case of 50 individually sealed units, this sterile single-use component is standard hardware for high-throughput flow cytometry, stem cell processing, and primary cell line isolation loops.

Technical Performance & Architecture

• Uniformly Spaced Nylon Mesh Trough: The straining surface is woven from high-strength nylon filaments featuring an absolute 40 µm mesh opening rating. This layout effectively retains cell clumps, connective tissue debris, and large cell aggregates while allowing single target cells to pass undamaged.
• Standard 50 mL Conical Fitment: The outer housing features an engineered lip and seating ring that seats flat against standard 50 mL conical tubes. This prevents fluid bypass, shifting, or airlocks during fast, high-volume wash steps.
• Aseptic Blister Package Isolation: Every cell strainer arrives gamma-irradiated and sealed in a standalone, medical-grade paper-plastic blister pouch. This ensures that the strainer remains completely free of ambient dust and cross-contamination until the package is opened within a biosafety cabinet.
• Molded Finger Tab Handle: Designed with an integrated, elongated plastic grip tab. This allows operators to easily insert and extract the strainer from the 50 mL conical tube using forceps or gloved fingers without touching the inner fluid track or sterile rim.

Key Benefits & Applications

• Flow Cytometry Sample Clarification: The premier choice for clearing cellular aggregates, tissue clumps, and debris from blood, spleen, or lymph node samples prior to cell sorting or FACS analysis, preventing instrument nozzle clogs.
• Primary Stem Cell Isolation Loops: Provides a gentle, non-shearing filtration method for gathering mesenchymal stem cells, neural clusters, or primary tumor cells from enzymatic or mechanical organ dissociation pools.
• Immunology & Spleen Dissociation Protocols: Ideal for quickly filtering single-splenocyte suspensions during antibody screening, immune cell profiling, or cell culture expansion prep routines.
• **Streamlined Cleanroom Tracking:** Each standalone sterile pouch is printed with the manufacturer lot code and expiration metric to support complete, audit-ready batch traceability.

Falcon® is a registered commercial trademark of Corning, Inc. Catalog number 352340 specifies the blue-coded 40 µm configuration. For working with larger cellular targets or thicker tissues that require coarse filtration steps, companion 70 µm white (SKU 352350) or 100 µm yellow (SKU 352360) variants must be integrated into the procurement pipeline instead.
