Corning 9186 Aspirating Pipet 2 ml Polystyrene Individually Wrapped Case of 1000 Pipets

Corning Costar 2 mL Polystyrene Aspirating Pipets (9186) – Case of 1000

The Corning Costar 9186 is a cleanroom-grade, completely ungraduated liquid handling utensil engineered specifically for aseptic aspiration, media evacuation, and biological waste removal loops. Molded as a seamless, single piece from exceptionally clear virgin polystyrene, these 2 mL pipets are entirely unplugged (without a cotton or fiber filter) to facilitate continuous vacuum suction. Provided pre-sterilized and individually wrapped inside a high-volume factory case of 1000 units, this validation-ready configuration guarantees strict fluidic isolation and eliminates the risk of sample carryover in critical cell culture lines.

Technical Performance & Design

• Seamless One-Piece Construction: Molded as a uniform polystyrene unit without structural joints or internal weld seams. This completely smooth interior channel prevents liquid pocketing, ensuring unrestricted fluid dynamics under active vacuum.
• Ungraduated and Unplugged Fluid path: Designed deliberately without volumetric markings or internal cotton matrix barriers, eliminating any particulate components that could trap infectious aerosols or obstruct high-velocity suction streams.
• Aseptic Round Tip Geometry: Engineered with a smooth, rounded tip configuration that facilitates precision fluid drawing from the absolute perimeter corners of tissue culture vessels without gouging growth surfaces or damaging delicate adherent cells.
• Individually Wrapped Purity Envelopes: Each pipet is housed inside a dedicated, peel-to-open plastic/paper pouch to assure sterile integrity right up to the exact moment of processing inside biosafety cabinets.

Key Benefits & Applications

• Cell Culture Supernatant Removal: Provides the perfect sterile pathway for clearing spent media layers from multi-well clusters, culture dishes, and roller bottles prior to down-stream washing or trypsinization.
• Aseptic Fluid Aspiration Loops: Connects easily with standard silicone or rubber laboratory vacuum lines via standard pipet controllers or inline vacuum manifold adapters.
• Cross-Contamination Prevention: The economical disposable format bypasses resource-intensive washing, rinsing, and sterilization verification steps required for reusable glass pasteur pipets.
• Eco-Conscious Manufacturing Compliance: Produced in Corning facilities that are completely covered by renewable energy attribute certificates (EACs), aligning with modern corporate green procurement initiatives.
