Fisherbrand Aspirating Pipette 2 ml Case of 200 Pipets

Description

Fisherbrand Disposable Aspirating Pipette – 2 mL, Transparent Polystyrene, No Graduations, Unplugged, Sterile (MPN: 14955135)

The Fisherbrand 14955135 (also cataloged as 14-955-135) is a premium, single-use 2 mL aspirating pipette engineered for fluid transfer, media aspiration, and general washing protocols in cell culture and clinical diagnostic workflows. Molded from ultra-pure, crystal-grade transparent polystyrene, this pipette is purposefully designed without volumetric graduations and features an open, unplugged top (no cotton or polyester plug). This specific architecture makes it highly optimized for routine vacuum aspiration lines, liquid waste removal, and quick media addition steps, eliminating the risk of internal fluid hang-up or vacuum line clotting caused by standard fibrous filter plugs.

Technical Performance and Design

• Unplugged Fluid Path Efficiency: Formulated without internal cotton or polyester plugs, allowing for rapid, unhindered continuous vacuum suction without the risk of wet-out filter blockages stalling aspiration lines.

• Pristine Non-Graduated Optical Clarity: The smooth, crystal-clear polystyrene body contains no printed ink markings or molded scale steps. This design maximizes visual clarity inside the tube, helping researchers track cells, interfaces, or particulates during fluid draw passes.

• One-Piece Seamless Construction: Fabricated using an advanced single-piece molding technique that eliminates structural weld seams. This eliminates sample trapping and minimizes internal fluid shear forces when working with delicate primary cell lines.

• Individually Wrapped Aseptic Protection: Processed via validated gamma irradiation to achieve a 10⁻⁶ Sterility Assurance Level (SAL). Each unit is enclosed in a medical-grade paper/plastic peel-to-open sleeve to ensure complete aseptic delivery into sterile laminar flow hoods.

Key Benefits & Applications

• Cell Culture Media Waste Removal: The industry-standard tool for vacuum-drawing spent media supernatant away from multi-well plates, petri dishes, and culture flasks prior to feeding steps.

• Centrifuge Pellet Washing: Highly effective for gently drawing off washing buffers and supernatant following sample centrifugation, without disturbing delicate cellular or nucleic acid pellets.

• Cross-Contamination Mitigation: Shifting from reusable glass Pasteur pipettes to these single-use disposable units removes laboratory cleaning overhead and prevents cross-batch biomaterial carryover.

• Universal Pipette Controller Fit: Standardized upper stem sizing ensures a secure, leak-proof mechanical fitment when inserted into automated motorized pipetting guns or manual safety bulbs.
