Thermo Scientific Serological Pipet 5 ml Polystyrene 400 Pipettes

Thermo Scientific Nunc 170355 Serological Pipette – 5 mL, Polystyrene, Sterile

The Thermo Scientific 170355 is a 5 mL serological pipette engineered under the Nunc brand for the precise volumetric measurement and transfer of aqueous solutions. Molded from 100% virgin polystyrene to provide maximum optical clarity, this disposable pipette is utilized for handling cell culture media, biological buffers, and chemical reagents. Each unit is equipped with a synthetic aerosol-barrier plug at the top opening, which acts as a physical safeguard to prevent aspirated fluids from entering and contaminating motorized pipette controllers. Packaged individually in easy-to-open paper/plastic peel wrappers, these pipettes are sterilized by gamma irradiation and certified non-pyrogenic to support demanding in vitro biological assays and routine tissue culture workflows.

Technical Performance and Design

• Precision Graduations: Features bold, easy-to-read bi-directional markings for both aspirating and dispensing. It also includes negative graduations, providing additional working capacity beyond the nominal 5 mL limit.

• Aerosol Barrier Plug: The integrated cotton/synthetic plug stops fluid and aerosols from accidentally entering the mechanical pipet filler, protecting the instrument and completely preventing batch-to-batch cross-contamination.

• Drip-Free Tip: The precision-molded dispensing tip maintains fluid surface tension, preventing liquids from prematurely dripping during transfer to ensure exact volumetric delivery.

• Optical Polystyrene: The high-grade polystyrene construction provides glass-like clarity, enabling laboratory technicians to visually monitor the meniscus and easily spot unwanted air bubbles or particulate matter.

Key Benefits & Applications

• Cell Culture Operations: The standard consumable for aliquoting liquid media, dispensing dissociation enzymes (like trypsin), and washing adherent cell lines within strict Class II laminar flow hoods.

• Universal Compatibility: The standardized top geometry ensures a secure, airtight fit into mechanical pipette controllers, manual pumps, and rubber bulbs from all major laboratory manufacturers.

• Color-Coded Identification: Both the pipette and the individual wrapper feature industry-standard color-coding (blue for 5 mL), allowing users to instantly identify the correct volume size from crowded laboratory storage racks.

• Aseptic Handling: The individual peel-apart wrappers guarantee that the external and internal surfaces of the pipette remain completely sterile until the exact moment of use.
