Autoclaves:
Autoclaves use steam under pressure to kill harmful bacteria, viruses, fungi, and spores on items that are placed inside a pressure vessel. The machine works by heating water to produce steam, which is then pressurized and used to sterilize equipment and supplies. Autoclaves are widely used in microbiology and mycology, medicine and prosthetics fabrication, tattooing and body piercing, and funerary practice.
