An inoculation loop, also called a sterile flexi loop or nichrome loop, is a simple tool used mainly by microbiologists to pick up and transfer a small sample (inoculum) from a culture of microorganisms having size of 2.2mm and 4mm and available in calibrated to 0.005ml and 0.01ml . Inoculation loop is made up of polystyrene material, gamma Irradiated easy to handle and dispose. Nichrome loops have some disadvantages such as, it required to cool down for the room temperature after flaming and then it can be used , so its time consuming and if nichrome loop not cool down properly then it may kill the bacterial from sample, from where we need to collect the sample and it may give us false negative reports. Disposable inoculating loops and needles eliminate the risk of infection because they do not need flaming and thus form the aerosol of pathogenic substances. improper sterilization is eliminated because of Cross-contamination.
