The Science of Autoclave Sterilization
EXECUTIVE_SUMMARY
This standard defines the hydrothermal conditions required to achieve medical-grade sterility (SAL 10⁻⁶) in body art environments.
Sterilization is the process of destroying all forms of microbial life, including highly resistant bacterial spores. In the tattoo and piercing industry, the gravity-displacement or prevacuum autoclave is the gold standard for biosecurity.
The Critical Variables: Heat, Pressure, and Time
Successful sterilization requires the precise coordination of saturated steam, temperature, and duration. For most modern studio environments, the 134°C (273°F) cycle is preferred for its efficiency.
- Conditioning: Air is removed from the chamber via vacuum or displacement to allow steam penetration.
- Exposure: The core sterilization phase where the items are held at technical benchmarks.
- Exhaust: Steam is released and pressure is equalized.
- Drying: Vital to prevent "wicking" — where moisture pulls bacteria through sterile packaging.
