Fisherbrand Cell Spreader L-Shaped Sterile Individually Wrapped

Fisherbrand 14665231 L-Shaped Cell Spreader – Sterile, Individually Wrapped

The Fisherbrand 14665231 is a precision-molded, L-shaped cell spreader engineered for the rapid and uniform distribution of liquid samples across the surface of agar plates and culture media. Manufactured from high-impact, medical-grade polystyrene, these spreaders feature a completely smooth, rounded finish that eliminates the risk of scratching or puncturing the delicate agar surface. The L-shape design provides a 145 mm handle for easy manipulation and a 35 mm spreading bar that maintains a perfectly flat contact area, ensuring a consistent inoculum spread every time. These spreaders are supplied individually wrapped and certified sterile, providing a ready-to-use, disposable solution that eliminates the need for time-consuming glass rod sterilization and the hazardous use of open flames and ethanol in the microbiology hood.

Technical Performance and Design

• Ergonomic L-Shape: The 90-degree "L" geometry ensures that the spreading surface is always parallel to the agar, allowing for even pressure distribution and consistent lawn growth across the entire plate.

• Incidental Puncture Prevention: Unlike bent glass rods, the injection-molded polystyrene has no sharp edges or burrs, protecting the integrity of the media and preventing the accidental "digging" that can ruin a sample.

• Individually Wrapped: Each spreader is sealed in a separate peel-pack, ensuring absolute sterility and preventing the contamination of a bulk stock when only a single unit is required for a procedure.

• Static-Free Material: Formulated to minimize static electricity, ensuring that the liquid sample remains on the agar surface rather than clinging to the spreader handle.

Key Benefits & Applications

• Bacterial Colony Counting: Essential for the spread-plate method of enumeration, ensuring that colonies are distributed evenly enough to be accurately counted without overlapping.

• Antibiotic Sensitivity Testing: Used to create a perfectly uniform bacterial lawn required for Kirby-Bauer disc diffusion assays and E-tests.

• High-Efficiency Microbiology: A favorite for busy diagnostic labs and student classrooms, where the speed of a pre-sterilized disposable tool significantly increases sample throughput.

• Safety & Compliance: Eliminates the fire hazard and aerosolization risks associated with "flaming" glass or metal spreaders in laminar flow hoods.
