NiChrome Wire Loops, Handles, Combo-Loops, and Tool-Gauges


Loops and Spreaders Overview >

Copan offers a wide selection of economical and durable NiChrome Wire Loops (calibrated and non-calibrated), Handles, and Combo Loops with different benefits. Some of the benefits of Copan NiChrome Wire Loops line include:

Ultra Smooth

No gouging of agar: Copan NiChrome wire loops have totally smooth surfaces and will not cut or gouge through agar medium when streaking plate cultures.

Flexible and Rapid Cooling

Loops are made of an 80/20 Nickel-Chrome metal wire for durability and rapid cooling following heat sterilization. A strand of wire is molded around a specific pin size to form the loop shape and then the ends of wire strand are twisted together. The testing process gives the loops its characteristic flexibility.

Durable and Economical

Designed to be durable and long lasting, Copan NiChrome loops last many weeks or months depending on the intensity of use. They cost less than traditional platinum-rhodium loops.

Combo-Loops (combined loop and handle)

A range of NiChrome Wire Loops attached to light weight insulated aluminum handles is available. Combo-loops are non-calibrated and available in a range of loop sizes 2, 3, 4 and 5mm internal diameter (Ø). Combo-Loop handles are color coded to facilitate easy size identification. They offer the convenience of a ready-to-use loop and handle combination. Like regular NiChrome loops, Combo-Loops are sterilized between uses with an incinerator or Bunsen flame. The whole unit is designed to be discarded when the wire loop wears out.

TOOL GAUGES

Continual heating and cooling of the NiChrome Wire Loops to sterilize between use means there is always a risk that the 1µL and 10µL calibrated loops can become distorted or there is an excessive build up of burnt organic material on the surface of the loop. Both conditions can significantly alter the liquid volume delivered by the loop and hence the accuracy. Copan offers a simple QC procedure for checking the accuracy of the loops using a GoNoGo tool gauge for both 1µL and 10µL based upon the FDA Drill Bit Method for checking the calibration of metal loops.
