Fabricated from premium, high-clarity virgin polystyrene, these 2 mL pipettes are intentionally manufactured without graduations and without an internal plug filter. This non-plugged, open-bore architecture maximizes suction throughput and facilitates uninterrupted liquid transfer. Supplied sterile and individually wrapped in a case of 500 pipettes, this product ensures an absolute aseptic barrier for critical cell culture maintenance loops.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePlugless High-Velocity Flow Channel: Designed without a cotton or polyester plug insert, completely eliminating the risk of filter blockage or vacuum restriction during high-volume liquid draw or cell debris extraction.\u003c\/li\u003e\n\u003cli\u003eOptically Clear Virgin Polystyrene: Molded from pure, optical-grade polystyrene resins to provide an unhindered visual path, allowing operators to monitor fluid clarity, capture color transitions, or detect accidental cell pellet uptake.\u003c\/li\u003e\n\u003cli\u003eAseptic Individual Peel-Pack Wrap: Each pipette is hermetically sealed within an easy-to-peel paper\/plastic wrapper.
