Science teachers and lab technicians, this classpack of 15 inoculation loops is exactly what you need for microbiology work! Each loop measures 11 inches total with a sturdy 8-inch aluminum handle that feels solid in your hand. The business end features a 3-inch section of twisted nickel-chromium alloy wire ending in a perfect 3mm diameter loop - ideal for selecting, transferring, or inoculating microbiological samples. The aluminum handle is genius because it cools down quickly after flame sterilization, meaning you're not waiting around forever between samples. These loops are built to be reused multiple times - just flame sterilize between uses and they're good to go again. The nickel-chromium wire can handle repeated heating without degrading, making these way more cost-effective than disposable options. Perfect for classroom demonstrations, student labs, or professional microbiology work. Having 15 loops means you can equip a whole lab group or have plenty of backups on hand. The twisted wire design provides just the right amount of flexibility while maintaining that perfect loop shape. Whether you're streaking agar plates, making bacterial transfers, or teaching proper aseptic technique, these reliable inoculation loops make the job so much easier. Seriously, if you're tired of flimsy disposable loops or want to save money in the long run, this classpack is the way to go!
