Fisherbrand Serological Pipette 5 ml PS Case of 200 Pipets

Fisherbrand® 5 mL Clear Polystyrene Serological Pipettes, Individually Wrapped (13-678-11D) – Case of 200

The Fisherbrand® 13-678-11D is a foundational, research-grade liquid handling consumable engineered for high-accuracy fluid aspiration, cell culture feeding, and chemical reagent delivery. Precision-extruded from premium, optically clear virgin polystyrene, these 5 mL serological pipettes feature a uniform structural bore that guarantees excellent linear accuracy and meniscus stability. Each pipette is equipped with a non-binding polyester filter plug that blocks fluid overflow and aerosol tracking from entering automated pipetting controllers. Supplied as a commercial facility case of 200 individually paper-plastic peel-wrapped units, this sterile single-use model delivers absolute aseptic performance for clinical diagnostics, bioprocessing cleanrooms, and tissue culture installations.

Technical Performance & Architecture

• Bi-Directional High-Contrast Graduation Scale: Features high-contrast printed markings calibrated to deliver (TD) within a strict tolerance of $\pm 2\%$. The dual-scale typography displays ascending and descending volumes, supplemented by negative graduations extending up to an additional 2.5 mL of overfill capacity.
• Aerosol Barrier Polyester Plug: Outfitted with a premium, friction-fitted synthetic filter plug inside the mouthpiece socket. This barrier intercepts unexpected liquid backflow and aerosol migration, safeguarding the internal filter and piston matrix of motorized pipet fillers against cross-contamination.
• Seamless One-Piece Construction: Advanced manufacturing processes eliminate structural weld joints or internal seams in the pipette barrel. This seamless geometry minimizes fluid retention, drastically reduces sample-shearing friction, and suppresses tip-dripping tendencies during slow cell-suspension seeding.
• Aseptic Peel-Pack Isolation: Individually sealed inside a medical-grade paper-plastic blister wrapper. The heavy-duty pouch allows cleanroom technicians to peel open the casing easily and drop the sterile instrument into a laminar flow biosafety hood without producing paper dust or static particulate attachment.

• **Lot-Specific Compliance Tracking:** Every standalone blister wrapper is printed with the direct manufacturing lot number and expiration date metric to ensure seamless compliance tracing inside cGMP biomanufacturing hubs.

Fisherbrand® is a registered commercial trademark of Thermo Fisher Scientific Inc. Catalog number 13-678-11D specifies the individually wrapped 5 mL clear polystyrene pipette. For high-volume discovery screens where individual unwrapping creates operational drag, companion bulk-packed multi-packs or alternative capacity configurations (such as 10 mL or 25 mL variants) must be substituted within the procurement system.
