Autoclave Charles Chamberland in 1884, although a precursor known as the steam digester was created by Denis Papin in 1679. The name comes from Greek "auto-", ultimately meaning self, and Latin "clavis" meaning key, thus a self-locking device. Sterilization autoclaves are widely used in microbiology, medicine, podiatry, tattooing, body piercing, veterinary medicine, mycology, funerary practice, dentistry, and prosthetics fabrication. They vary in size and function depending on the media to be sterilized and are sometimes called retort in the chemical and food industries. Typical loads include laboratory glassware, other equipment and waste, surgical instruments, and medical waste. A notable recent and
Sterilization (microbiology) heat sterilization process (this is one trait that differs from a typical pressure cooker used for food cooking). The article is held at the temperature setpoint for a period of time which varies depending on what bioburden is present on the article being sterilized and its resistance (D-value) to steam sterilization. A general cycle would be anywhere between 3 and 15 minutes, (depending on the generated heat) at at , which is sufficient to provide a sterility assurance level of 10 for a product with a bioburden of 10 and a D-value of 2.0 minutes. Following sterilization, liquids in a
