Fisherbrand Disposable Plastic Laboratory Syringe - 1 mL, Luer Lock Tip, Polypropylene, Sterile, No Needle (MPN: 14955456)

Expiration Date: 2022-11-21

The Fisherbrand 14955456 (also cataloged as 14-955-456) is a premium, single-use 1 mL plastic laboratory syringe precision-engineered for small-volume fluid filtration, micro-sample aspiration, and high-accuracy dispensing workflows. Fabricated from medical-grade, inert natural polypropylene, this three-part manual syringe features a high-purity concentric Luer Lock tip configuration. This threaded mechanical connection establishes a highly secure, leak-proof link when coupled to standard female Luer hubs, micro-inline syringe filters, fluidic manifolds, or low-volume chromatography adapters. Supplied individually wrapped inside aseptic paper/plastic peel blister pouches, this non-toxic syringe guarantees a clean, contaminant-free fluid path for demanding biochemical and analytical research applications.

Technical Performance and Design

• Threaded Luer Lock Micro-Stability: Outfitted with a precision-molded, centralized Luer Lock tip collar. The threaded physical locking mechanism prevents high-pressure blowout or fluid spraying when forcing micro-volumes through ultra-fine syringe filters or dense analytical lines.

• Three-Part Polymer Gasket Assembly: Built using a smooth-gliding three-part layout composed of a clear polypropylene barrel, a matching plunger piston, and an elastomeric rubber sealing gasket. This internal jacket blocks 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 along the slim exterior barrel wall. This layout supports rapid, error-free liquid alignment and exact fluid-level tracking down to fractions of a milliliter for small dosing lines.

• 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 protect against ambient shop dust or external biological pollutants.

Key Benefits and Applications

• Micro-Filter Sample Preparation: The ideal pressure-driver vessel for forcing micro-volume aqueous solutions, protein extracts, or biological buffers through small 4 mm or 13 mm syringe filter membranes prior to HPLC or analytical injections.

• Controlled Reagent Additions: Extensively utilized within biosafety hoods to cleanly draw, measure, and transfer up to 1 mL of sensitive cell culture reagents, active enzymes, or working small-molecule standards.

• 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 wide mechanical finger flanges along the upper rim and a stable plunger top button, giving technicians a steady, non-slip grip when handling fluids with damp nitrile laboratory gloves.
