Which tool is used to transfer microbes or cultures in a laboratory setting?

• A. Scalpel handle
• B. Inoculating loop
• C. Pipette
• D. Beaker

Answer: (B)

The inoculating loop is the correct tool for transferring microbes or cultures in a laboratory setting because it is specifically designed for this purpose. This tool is usually made of metal or plastic and features a wire loop that allows for the precise collection and transfer of small amounts of microbial cultures from one medium to another. The loop can be sterilized by passing it through a flame, which is essential for maintaining sterile conditions and preventing contamination during microbiological work. In contrast, a scalpel handle is intended for cutting and dissecting rather than transferring cultures. Pipettes are more commonly used for transferring liquids in various volumes, often in chemical or biochemical applications, but are less suited for solid or semi-solid microbial media. A beaker is a container used to hold or mix liquids and does not serve the purpose of transferring cultures or microbes. Thus, the inoculating loop stands out due to its design and application specifically suited for handling microbial cultures.
