Designed to be durable and long lasting, these non-calibrated nichrome inoculation loops have completely smooth surfaces that will not tear or gouge through agar medium when streaking plate cultures. 3 mm ø - 26 Ga. Size NiChrome Wire Inoculating Loop - 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
