A wooden loop is a laboratory tool used for handling or manipulating small specimens, such as microorganisms, cells, or small particles. It consists of a thin metal wire or rod that is bent into a loop shape and mounted on a wooden handle for ease of use.
To use a wooden loop, the loop is sterilized by heating it until it glows red hot and then allowed to cool. The loop can then be used to pick up a small amount of the specimen and transfer it to a new location, such as a petri dish or microscope slide.
Wooden loops are often used in microbiology and other fields of biology to isolate and study individual specimens. They are also commonly used in educational settings to teach students how to handle and manipulate small objects under a microscope.
