Aseptic techniques ensure the microorganisms being investigated do not escape or become contaminated with an unwanted microorganism.

The growth of unwanted, pathogenic microorganisms is also prevented.

Aseptic techniques include:

  • No eating or drinking in the lab.
  • Wiping bench with disinfectant/alcohol.
  • Not growing microorganisms at body temperature.
  • Using sterile loops when transferring cultures.
  • Flaming culture bottle necks to prevent contamination.
  • Sterilising (using an autoclave) or disposing of all used equipment.
  • Washing hands thoroughly
