Falcon Centrifuge Tube 5 ml Case of 500 Tubes

Falcon 352058 5 ml Round-Bottom Test Tubes (Polystyrene, Sterile)

The Falcon 352058 is a high-quality 12 x 75 mm test tube engineered for precision and reliability in clinical and research laboratories. Manufactured from crystal-grade virgin polystyrene, these tubes offer exceptional optical clarity, making them the industry standard for flow cytometry (FACS), cell sorting, and high-resolution imaging applications. Each tube features a dual-position snap cap that provides both a vented position for aerobic incubation and a secure, leak-resistant seal for sample transport and centrifugation. Sterile and non-pyrogenic, these tubes are essential for aseptic cell culture workflows and sensitive diagnostic assays.

Technical Performance and Design

• Exceptional Optical Clarity: The polystyrene construction provides a distortion-free transparent finish, which is critical for accurate laser-based detection in flow cytometers and for visual sample inspections.

• Dual-Position Snap Cap: The polyethylene cap features two distinct positions: a loose "vent" position for consistent gas exchange during incubation, and a fully depressed "seal" position for a liquid-tight closure during vortexing and transport.

• Round (U) Bottom Geometry: The precision-molded round base ensures uniform pelleting of cells during centrifugation and allows for easy sample aspiration with automated probes or manual pipettes.

• Strict Manufacturing Standards: Produced under rigorous quality control to ensure dimensional consistency (12 x 75 mm), facilitating seamless compatibility with standard centrifuge rotors and flow cytometer loaders.

Key Benefits & Applications

• Flow Cytometry (FACS): The most widely used tube for preparing and running cell suspensions through flow cytometers like the BD FACSCanto™ or BD LSRFortessa™.

• Cell Culture & Immunology: Ideal for small-scale cell suspensions, dilutions, and immunological assays where a sterile, non-toxic environment is mandatory.

• Laboratory Versatility: Frequently used for RIA, ELISA titrations, and general sample storage where high visibility of the sample is required.

• Reliable Seal: The snap-cap design eliminates the risk of cross-contamination or evaporation, making these tubes suitable for both short-term incubation and high-speed vortexing.
