Fisherbrand Cell Spreader L-Shaped Sterile 340 Spreaders

Fisherbrand 14665230 Cell Spreader – L-Shaped, Polypropylene, Sterile, 10/Pouch

The Fisherbrand 14665230 is a sterile, disposable L-shaped cell spreader engineered for the rapid, even dispersion of bacterial and fungal cultures across agar plates. Manufactured from high-quality blue polypropylene, these single-use spreaders completely eliminate the hazardous, time-consuming need for flame sterilization and the tedious cooling periods associated with traditional glass or metal spreaders. Featuring a precision-molded smooth spreading surface with a slight upward angle, the 14665230 drastically reduces the risk of gouging or tearing the delicate agar surface. Supplied pre-sterilized and conveniently packaged with 10 spreaders per peel pouch, it is an essential consumable for high-throughput microbiology, clinical diagnostics, and molecular biology laboratories.

Technical Performance and Design

• Optimized L-Shape Geometry: The L-shaped design allows the user to apply gentle, downward pressure while sweeping the entire surface of a standard Petri dish in a single fluid rotation, ensuring uniform colony distribution.

• Upward-Curved Spatula Edge: The distal end of the spreader features a slight, upward-curved lip. This critical design element prevents the edge from catching, slicing, or gouging the agar medium during rapid plating.

• High-Visibility Blue Polypropylene: The bright blue coloration provides excellent visual contrast against pale agar media and bacterial lawns, making it easier for technicians to monitor their spreading technique.

• Pre-Sterilized Convenience: Completely eliminates the workflow bottlenecks of dipping glass spreaders in ethanol and flame sterilizing them, dramatically increasing plating throughput while removing a major fire hazard from the biological safety cabinet.

Key Benefits & Applications

• High-Throughput Microbiology: The ideal tool for rapidly plating serial dilutions, antibiotic susceptibility tests, and transformed E. coli colonies onto LB agar plates.

• Aseptic Workflow Efficiency: The 10-per-pouch packaging is perfectly portioned for processing medium-sized batches without exposing an entire bulk bag to airborne laboratory contaminants.

• Agar Preservation: The smooth, snag-free surface ensures that the agar remains intact, which is critical for accurate colony counting and preventing the pooling of liquid media in gouges.

• Enhanced Safety: By switching to disposable polypropylene, labs can remove open-flame Bunsen burners and beakers of highly flammable ethanol from crowded lab benches and laminar flow hoods.
