Our loops cool quickly and the smooth rounded tip slides across media without cutting or tearing. Inoculating loops are used to transfer cells to a growth medium. Loops are used in scientific labs, or at home for creating yeast banks for home brewing or wine making. They are also used in the cultivation of mushrooms. In use an inoculation loop is first passed through a flame heating the loop red hot this insures the loop is completely sterile. The loop is then cooled allowing a sterile transfer to the growth media. 24 Gauge Nichrome wire = 0.02 inches or 0.5 mm in diameter. Chemical Composition of Nichrome A: 80% Nickel, 20% Chromium Approx. Melting Point: 1400°C (2550°F) To see a complete listing of all Hall Bio inoculating loops go to the top of this page and click on blue Hall Bio link just above the product title. ## Features - Made from high quality 24 gauge nichrome A wire - Made in the USA - Hall Bio inoculating loops cool quickly and the smooth rounded tip slides across media without cutting or tearing - This is the replaceable nichrome loop only, must be placed in suitable handle for use. - 4mm Internal Diamiter; 100mm in length; 3 Pack ## Images ![604-03 4mm x 100mm Reusable Inoculating Loops, Nichrome A (3 Pack) - Image 1](https://m.media-amazon.com/images/I/818g3RuajAL.jpg) ![604-03 4mm x 100mm Reusable Inoculating Loops, Nichrome A (3 Pack) - Image 2](https://m.media-amazon.com/images/I/81WUTYafh8L.jpg) ![604-03 4mm x 100mm Reusable Inoculating Loops, Nichrome A (3 Pack) - Image 3](https://m.media-amazon.com/images/I/81Ba9k8rQfL.jpg) ![604-03 4mm x 100mm Reusable Inoculating Loops, Nichrome A (3 Pack) - Image 4](https://m.media-amazon.com/images/I/513qOVUOMEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect size *by M***S on June 27, 2022* Will work perfectly for my mushroom spore transfer. ### ⭐⭐⭐⭐⭐ Nice product *by H***R on April 6, 2020* Like the length and stiffness of the twisted wire.
