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
