What is autoclave sterilisation?

An autoclave is a sealed chamber that operates under high pressure and temperature, typically around 121-135°C, to sterilise reusable equipment through steam. In tattoo studios, autoclaves process needles, ink caps, grips, and other non-disposable tools that come into contact with skin and blood during procedures.

The machine works by forcing pressurised steam into direct contact with equipment for a set cycle, usually 15 to 30 minutes, which kills bacteria, viruses, spores, and other pathogens that ordinary cleaning cannot remove. This process is more thorough than washing or disinfecting sprays alone.

For London tattoo studios operating under local health and safety regulations, autoclave sterilisation is essential to prevent infection risks such as hepatitis B and C, staph infections, and other bloodborne illnesses. Studios must use NHS-verified or equivalent medical-grade autoclaves and follow documented sterilisation protocols. Regular testing and maintenance of the machine, along with proper documentation of sterilisation batches, form part of professional hygiene standards that customers should expect to see evidence of when choosing a studio.

A functioning autoclave demonstrates that a studio takes cross-contamination seriously and operates at professional infection-control standards, rather than relying solely on single-use disposable equipment.
