Autoclave Autoclave An autoclave is a pressure chamber used to carry out industrial processes requiring elevated temperature and pressure different from ambient air pressure. Autoclaves are used in medical applications to perform sterilization and in the chemical industry to cure coatings and vulcanize rubber and for hydrothermal synthesis. They are also used in industrial applications, especially regarding composites, see autoclave (industrial). Many autoclaves are used to sterilize equipment and supplies by subjecting them to pressurized saturated steam at 121 °C (249 °F) for around 15–20 minutes depending on the size of the load and the contents. The autoclave was invented by
Meaning (philosophy of language) refine and/or refute proposed meanings and truths. Though not widely known, a new variation of the pragmatic theory was defined and wielded successfully from the 20th century forward.

James and Dewey's ideas also ascribe meaning and truth to repeated testing which is "self-corrective" over time. Pragmatism and negative pragmatism are also closely aligned with the coherence theory of truth in that any testing
