What is NOT an example of aseptic technique?

The correct choice, which identifies an action that does not align with aseptic techniques, is the use of a non-sterile instrument. Aseptic technique involves practices aimed at minimizing contamination by pathogens and maintaining sterility in environments where microbial growth could pose risks, particularly in laboratory and clinical settings.

Using sterile instruments is essential in these practices, as any non-sterile instrument can introduce harmful microorganisms into a clean environment, potentially leading to infections or contamination of samples. On the other hand, actions such as wearing gloves, washing hands, and disinfecting surfaces are all proactive steps that help create a sterile environment, thereby supporting the principles of aseptic technique. These practices collectively work to reduce the risk of microbial contamination when performing procedures, handling samples, or conducting experiments.
