Fisherbrand Cell Strainer 70 um Individually Sealed 31 Cell Strainers

Fisherbrand 22363548 70 µm Cell Strainer (Nylon Mesh, Sterile, Individually Wrapped)

The Fisherbrand 22363548 is a high-quality laboratory tool designed for the rapid isolation of primary cells and the preparation of uniform single-cell suspensions. Featuring a 70 µm pore size nylon mesh, this strainer effectively removes cell aggregates, clumps, and tissue debris from samples, ensuring the integrity of downstream applications such as flow cytometry and primary cell culture. The strainer is engineered with a specialized polyproplyene frame that features a molded-in tab for easy aseptic handling and a vented design to prevent "air locks" and liquid overflow. Individually sealed and gamma-sterilized, these strainers are a reliable choice for critical research in immunology, oncology, and stem cell biology.

Technical Performance and Design

• 70 µm Precision Nylon Mesh: The evenly spaced, non-reactive nylon pores provide consistent filtration, allowing single cells to pass through while retaining larger tissue fragments and aggregates.

• Universal Conical Fit: Specifically designed to fit perfectly onto standard 50 ml conical centrifuge tubes, providing a stable platform for gravity-fed or pipette-assisted filtration.

• Ergonomic Handling: The extended molded tab allows for secure manipulation with forceps or gloved hands, minimizing the risk of accidental contact with the sterile mesh surface.

• Vented Frame Design: Integrated vents facilitate air displacement during filtration, preventing pressure buildup and ensuring a continuous, fast flow of the cell suspension into the collection tube.

Key Benefits & Applications

• Flow Cytometry Preparation: An essential step for filtering samples prior to FACS or flow analysis to prevent instrument clogging and ensure accurate single-cell data.

• Primary Cell Isolation: Ideal for dissociating cells from organ tissues (e.g., spleen, lymph node, or bone marrow) into a clean, viable suspension.

• Stem Cell Research: Used to remove embryoid bodies or clumps during the maintenance and expansion of pluripotent stem cell lines.

• Aseptic Convenience: Individually wrapped packaging ensures that each strainer remains sterile until the point of use, making them perfect for cleanroom and biosafety cabinet (BSC) workflows.
