Fisher Scientific Serological Pipette 50 ml PS Individually Sealed 75 Pipets

Fisherbrand 13-678-11 50 ml Serological Pipette (Polystyrene, Sterile)

The Fisherbrand 13-678-11 is a premium, high-capacity serological pipette designed for the precise transfer of large liquid volumes in cell culture, molecular biology, and microbiology workflows. Manufactured from crystal-grade virgin polystyrene, these pipettes offer exceptional optical clarity and are calibrated "To Deliver" (TD) with a full-outflow accuracy of +/- 2%. Each pipette is individually wrapped in a paper/plastic "peel-open" pouch to ensure maximum sterility and features a high-performance polyester aerosol barrier plug to prevent pipettor contamination and sample carryover.

Technical Performance and Design

• Exceptional Optical Clarity: The high-quality polystyrene construction provides a clear, distortion-free view of the meniscus, facilitating rapid and accurate volume readings during high-volume liquid handling.

• Ascending and Descending Graduations: Features bold, easy-to-read permanent black ink graduations in both directions, including negative graduations for additional working volume capacity.

• Aerosol Barrier Filter: Equipped with a high-quality bonded polyester plug that acts as a sterile barrier, protecting the internal mechanism of your pipette controller from liquid over-aspiration and aerosols.

• Non-Drip Tip Geometry: The precision-molded tip is engineered to provide consistent drop sizes and prevent accidental "dripping" when transferring low-viscosity liquids or media.
