Fisherbrand Tweezers 120 mm Long Polystyrene Blue Case of 500 Tweezers

Fisherbrand 14-955-029 General Purpose Tweezers – 120 mm, Polystyrene, Blue

The Fisherbrand 14-955-029 is a disposable, general-purpose laboratory tweezer designed for the precise handling of small samples and delicate parts where metal contact must be avoided. Measuring 120 mm in length, these distinctive blue tweezers are manufactured from a durable blend of standard and High-Impact Polystyrene (HIPS). Unlike their white counterparts, the 14-955-029 model features smooth, non-serrated tips (without teeth), making them ideal for handling soft, fragile, or easily scratched materials. Supplied non-sterile, they offer a cost-effective solution for everyday benchtop tasks, eliminating the labor of cleaning metal instruments and significantly reducing the risk of cross-contamination between samples.

Technical Performance and Design

• Non-Metal Construction: Ideal for protocols that require non-metallic, non-magnetic handling to prevent chemical reactivity, ion leaching, or magnetic interference with sensitive equipment.

• Smooth, Toothless Tips: Specifically engineered with flat, smooth tips for gripping delicate specimens, membrane filters, or electronic components without piercing or marring the surface.

• High-Impact Blend: Constructed from 67% Polystyrene (PS) and 33% High-Impact Polystyrene (HIPS) to provide the perfect balance of gripping rigidity and flex without snapping under applied pressure.

• Disposable Economy: The single-use plastic design provides a clean, uncontaminated tool for every new task, bypassing the need for tedious decontamination protocols.
