How to Sterilize and Inoculate Using an Inoculating Loop - Lab Procedure Guide #3329067 (License: Personal Use)

The image demonstrates a standard microbiological technique: first, the metal loop of an inoculating tool is heated in a flame until red-hot to ensure complete sterilization; second, after cooling briefly, the loop is dipped into a liquid or solid culture and then inserted into a sterile test tube to transfer the sample. This prevents contamination and ensures viable culture propagation.

Used in educational microbiology content, lab manuals, or online training modules where users seek visual guidance on aseptic technique for bacterial or fungal culture handling.
