Description

Fisherbrand Disposable Plastic Laboratory Syringe – 20 mL, Luer Lock Tip, Polypropylene, Sterile, No Needle (MPN: 14955460)

Expiration Date: 2022-11-26.

The Fisherbrand 14955460 (also cataloged as 14-955-460) is a premium, single-use 20 mL plastic laboratory syringe precision-engineered for small-volume fluid filtration, sample aspiration, and controlled dispensing. Fabricated from medical-grade, inert natural polypropylene, this three-part manual syringe features a high-purity concentric Luer Lock tip configuration. This threaded closure mechanics creates a highly secure, leak-proof attachment when coupled to standard female Luer hubs, inline syringe filters, fluidic adapters, or stopcock manifolds. Supplied individually wrapped inside aseptic paper/plastic peel blister pouches, this non-toxic syringe guarantees a pristine, contaminant-free fluid path for demanding biochemical, physical, and analytical research applications.

Technical Performance and Design

• Threaded Luer Lock Stability: Outfitted with a precision-molded, centralized Luer Lock tip collar. The threaded physical locking mechanism establishes a tight mechanical link that prevents high-pressure blowout or fluid spraying when pushing viscous liquids through ultra-fine syringe filters.

• Three-Part Polymer Gasket Assembly: Built using a smooth-gliding three-part layout composed of a clean polypropylene barrel, a matching structural piston plunger, and an elastomeric rubber sealing gasket. This internal jacket prevents fluid bypass while remaining entirely latex-free and pre-lubricated with a trace layer of biocompatible silicone oil.

• High-Contrast Volumetric Graduations: Features permanent, bold black scale lines imprinted running up the clear exterior barrel wall. This layout supports rapid, error-free liquid metrics alignment and exact fluid-level tracking down to fractions of a milliliter.

• Validated Gamma Sterilization: Processed via validated gamma irradiation protocols to secure an industry-standard aseptic baseline. Every unit is independently housed within a sealed blister wrapper to defend against ambient shop dust or external biological pollutants.

Key Benefits and Applications

• Syringe Filter Sample Preparation: The ideal pressure-driver vessel for forcing aqueous solutions, analytical extracts, or biological buffers through 13 mm and 25 mm syringe filter membranes prior to HPLC or ICP-MS analytical passes.

• Controlled Media Dispensing: Extensively utilized within cell culture hoods to cleanly draw, measure, and transfer up to 20 mL of cell culture broths, chemical additives, and complex enzyme reagents into downstream collection setups.

• Bypassed Cross-Contamination: The single-use disposable layout completely clears the facility of multi-hour hot cleaning cycles, decontamination washes, and carryover validation liabilities linked to legacy reusable glass syringes.

• Ergonomic Plunger Flanges: Designed with extra-wide mechanical finger flanges along the upper rim and a broad plunger top button, giving technicians a steady, non-slip grip when handling fluids with damp nitrile laboratory gloves.
