A range of nichrome wire loops attached to lightweight insulated aluminum handles. These loops are non-calibrated and available in a range of sizes 2, 3, 4, and 5mm internal diameter. Handles are color coded to facilitate easy identification. They offer the convenience of a ready-to-use loop and handle combination. The whole unit is designed to be durable and long lasting, these nichrome loops last many weeks or months depending on the intensity of use. They cost less than traditional platinum-rhodium loops and are designed to be discarded when the unit eventually wears out. 3 mm ø - 26 Ga. Size NiChrome Wire Loop with Aluminum Insulated Handle - Non-Calibrated

• Flexible loops, made from a twisted 80/20 blend of medical grade Nickel-Chrome wire that cools more quickly than other loop material, allowing laboratory technicians to work quickly
• Economical and durable NiChrome loops withstand frequent heating and cooling for thousands of streaks
• Precision crafted, ultra-smooth loops will not gouge agar medium when when performing delicate tasks
• Certified accuracy using FDA Drill Bit Method, with calibration certificate in every box of loops
• Combo-loops (combined loop + handle) offer the convenience of a ready-to-use system with loop attached to a lightweight insulated aluminum color coded handle
• Simple to use calibration tool gauge allows users to verify loop accuracy, ensuring that loop has not become distorted or encrusted with buildup of carbonized material from repeated flaming
