Thermo Scientific Nunc Serological Pipette 10 ml Sterile Lot of 400 Pipettes

Thermo Scientific Nunc 10 mL Standard Serological Pipettes, Sterile (170374N) – Lot of 400

The Thermo Scientific Nunc 10 mL Serological Pipettes (170374N) are high-precision, optical-grade liquid handling consumables designed for accurate volumetric measuring, cell culture media dispensing, and general reagent transfer. Precision-molded from ultra-clear virgin polystyrene, these serological pipettes feature bi-directional bold calibration graduations, including negative graduations for increased volumetric capacity. Equipped with a premium barrier filter plug to prevent fluid overflow and aerosol contamination of pipetting devices, each pipette is gamma-sterilized and individually wrapped in paper/plastic packaging to maintain sterility during aseptic transfers. Supplied as a commercial lot of 400 sterile pipettes (packaged as 2 inner boxes of 200 individually wrapped units), this product delivers certified cleanliness and batch-to-batch consistency for cell biology, microbiology, and clinical diagnostic workflows.

Technical Performance & Physical Design

• High-Clarity Virgin Polystyrene Construction: Precision-extruded from premium polystyrene to ensure maximum optical clarity and accurate visual meniscus alignment during liquid draws.
• Bi-Directional Bold Graduations: Features high-contrast, easy-to-read black ascending and descending scale markings, along with negative graduations that provide an additional 3 mL of working overfill capacity.
• Aerosol Barrier Plug: Outfitted with a premium hydrophobic polyester fiber filter plug at the top mouthpiece to prevent liquid overfill and safeguard electronic pipette controllers from internal contamination.
• Color-Coded ISO Standard Identification: Designed with an orange color-coded top ring and individual packaging accents corresponding to international standards for rapid 10 mL volume identification at the benchtop.
• Individual Paper/Plastic Peel Packaging: Wrapped in easy-peel paper/plastic packaging that facilitates clean, static-free opening inside laminar flow hoods and biosafety cabinets.

Key Benefits & Applications

• Aseptic Tissue Culture Workflows: Ideal for precise volumetric transfers of media, fetal bovine serum (FBS), trypsin, and wash buffers inside biosafety hoods.
• Aerosol & Cross-Contamination Protection: The integrated filter plug safeguards both the sample and the motorized pipette filler from back-flow and cross-contamination.
• Versatile Negative Graduation Range: The extra 3.0 mL negative graduation capacity allows technicians to fill slightly past the 10 mL mark to complete full volume dispenses without changing pipettes.
• Traceable Cleanroom Storage: Individual wrapping ensures that remaining pipettes stay 100% sterile and protected from laboratory ambient dust until the moment of use.
