70Pcs Reusable Nichrome Inoculating Loops with 2 Copper Handles, 3 Diameters Inoculation Loops, Needle Tips Rings Rods, Microbiological Loop for Lab (70pcs)

【70 INOCULATING LOOPS AND 2 HANDLES】You will get 70 replaceable inoculating needle loops in 3 diameters: 30pcs in 5mm (0.2") diameter, 30pcs in 3mm (0.12") diameter, 10pcs in 1 mm (0.04") diameter, and 2 black and blue copper inoculating loop holder. Copper handles in different colors can help you quickly distinguish inoculation loops of different diameters. 【DURABLE AND REUSABLE】Inoculating loops with insulated PVC handles are manufactured from high-quality nichrome, which is not easy to rust, high temperature resistant and can be cleaned in a flame. The inoculation rod is made of PP and copper, the surface is chrome-plated, and the layer can prevent oxidation of the inoculation rod. 【EASY TO USE】Inoculation rings are easy to use and make your experiments easier. Heat the inoculation loops with a flame before use till the loops glow, and wait for about 30 seconds until the inoculation loops cool down before contacting the experimental samples. 【PORTABLE AND QUICK REPLACEMENT】Our cell inoculation loops are light in weight and small in size, easy to carry, whether you go to the classroom or the laboratory, you can put them in a backpack or pocket. The inoculation needle are also very easy to replace, just pull out the old loop and insert a new one. 【NO DAMAGE TO YOUR SAMPLE】The surface of our microbial culture loop is smooth and round, and the gap at the closure is tiny.
