Fisher Scientific Serological Pipette 25 ml Polystyrene Case of 200 Pipettes

Fisherbrand® 25 mL Clear Polystyrene Serological Pipettes, Individually Wrapped (13-678-11) – Case of 200

The Fisherbrand® 13-678-11 is a large-volume, research-grade liquid handling consumable designed for precise fluid aspiration, media preparation, and large-scale volumetric dispensing. Precision-extruded from high-purity virgin polystyrene, these 25 mL serological pipettes feature a uniform internal diameter that guarantees excellent meniscus stability and a strict calibration tolerance of $\pm 2\%$. Each pipette incorporates a non-binding polyester filter plug that blocks fluid overflow and aerosol migration from entering electronic pipetting controllers. Supplied as a commercial case of 200 individually paper-plastic peel-wrapped units, this sterile, single-use model provides an absolute aseptic barrier for upstream cell culture maintenance, bioprocessing, and clinical diagnostic workflows.

Technical Performance & Architecture

• Bi-Directional High-Contrast Graduation Scale: Features permanent, bold printed markings calibrated to deliver (TD). The dual-scale typography displays ascending and descending fluid levels, supplemented by negative graduations extending down to provide an additional 10.0 mL of overfill volume capacity.
• Aerosol Barrier Polyester Plug: Outfitted with a premium, friction-fitted synthetic filter matrix inside the mouthpiece socket. This barrier intercepts unexpected liquid backflow and dynamic aerosol migration, protecting the internal filter and piston mechanics of motorized pipet fillers from cross-contamination.
• Seamless One-Piece Construction: Advanced manufacturing processes eliminate structural weld joints or internal seams along the pipette barrel. This seamless geometry minimizes fluid retention, drastically reduces sample-shearing friction, and suppresses tip-dripping tendencies during large-volume cell 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.
