What are aseptic techniques?
Aseptic techniques are essential practices used in
microbiology to prevent the unwanted
introduction of contaminants into a controlled
environment. These techniques ensure the
integrity and sterility of samples, cultures, and
equipment, enabling reliable and accurate results
in scientific research and medical procedures.
