Talk:Autoclave

message: This article is essentially limited to autoclaves used for sterilisation in biology medicine and cooking. The statement that they are used to reach a temperature of 121 C may reflect standard equipment in these fields but the concept is much more general and in e.g. chemical and hydrothermal synthesis and in industrial process like paper pulp production other and sometimes much higher temeperatures (and pressures) are needed.  — Preceding unsigned comment added by 150.227.15.253 (talk) 09:26, 5 August 2013 (UTC)
thread_title: Not general enough!!

message: I worked at a yarn plant that used a very large autoclave to set yarn.  It was a huge horizontal cylinder approximately 15 feet long and 6 feet in diameter.  Autoclaves are also used in the making of some liquers, I think.  I'd add some info, but I don't know enough. PrometheusX303 13:10, 15 June 2006 (UTC)

message: Autoclaves are commonly used in piercing shops to sterilize needles and jewelry before use, well, at least the good shops do. Apparently you can also cook in them??? —The preceding unsigned comment was added by 142.55.24.22 (talk • contribs).
:Go ahead and add it.  Not the cooking part, though.  It's not an appropriate use.  Better use a pressure cooker instead. Prometheus-X303- 05:07, 15 November 2006 (UTC)

thread_title:  Is there a low-cost substitute? 

message: Autoclaves are used in moulding composite materials such as carbon fibre. These are quite different to those described here, as they just use high pressure hot air within the pressure vessel to squeeze, activate and bond the materials. I think either this article needs to cover these types or needs to be renamed to Autoclave (medical) with a disambiguation page. --Ozhiker (talk) 16:38, 30 July 2008 (UTC)

thread_title:  Use with Composite Materials 

message: The section labeled "Introduction" talks (talked!) about how water can remain a liquid if heated under pressure.  This may be true, but I don't see how this material benefits the article.  Everything I've read about autoclaves say that they subject the parts to steam (water vapor) not liquid water.  Revert me if I've gotten it completely wrong, but for now I'm nixing the whole section about liquid.  Spiel496 (talk) 18:52, 10 April 2009 (UTC)
thread_title:  liquid water 

message: "It is critical that autoclaves be opened only after checking both the pressure and temperature gauges. If the water inside the autoclave has managed to become a superheated liquid, as opposed to steam, the pressure gauge may not indicate the presence of steam even though the temperature may be significantly higher than the local boiling point for water. If the autoclave is opened in this state and the superheated water is disturbed, a steam explosion becomes possible. This phenomenon can easily produce fatal burns to people in the vicinity of the explosion. Page 1, see admonishment not to autoclave recipients with liquids.  Autoclaves are themselves a recipient with liquid."
Firstly, all autoclaves that heat the water in the chamber (as opposed to injecting steam) have superheated water in them whenever they are above 100 deg C. & above ambient pressure.
Secondly, the reference isn't even about this subject. The reference states "Never autoclave a sealed vessel containing liquids as this may result in an explosion of super-heated liquid and steam during the cycle or when the vessel is opened."
Thirdly, I have a decade of experience on these things and have never experienced or even heard of superheated steam explosions. 
Fourthly, most medical autoclaves are far beyond 100 degrees Celsius when they complete the cycle as they finish up with a dry cycle.
Fifthly, most medical autoclaves have some kind of mechanism to prevent people opening the door if the chamber is under pressure.119.12.79.139 (talk) 12:47, 8 September 2009 (UTC)

message: The Pressure Cooker page links to the Autoclave page, but not vice versa. It might be useful to say something like "An autoclave is an industrial version of a _pressure cooker_. — Preceding unsigned comment added by 64.142.15.200 (talk • contribs) 02:48, 6 July 2012 (UTC)
thread_title:  Pressure cooker 

message: It makes little sense that autoclave redirects here, while autoclave (industrial) is relegated to a hidden article. The term is much wider than suggested here. At least move autoclave to autoclave (sterilization) and redirect autoclave to the disambiguation page. Just my three cents.  — Preceding unsigned comment added by 76.65.153.53 (talk) 03:44, 25 May 2016 (UTC)
replies: text: Since autoclave(industrial) no longer exists, the near complete lack of any mention of industrial autoclaves is troubling. Clearly the article hasn't been merged as its still almost entirely about medical autoclaves. 82.176.203.219 (talk) 01:41, 4 August 2023 (UTC)

message: The image under the heading of "Square Section Autoclave" is pretty clearly a cylindrical chambered autoclave.  Also, the caption says it's "high capacity," which is isn't.

thread_title: "square section" autoclave?

message: While reading through the article, I came across the section called "Air Removal" and started to wonder why air must be removed from the chamber before an autoclave can begin performing it's function. I was a little disappointed as the section does not explain why air must be removed from the chamber. Upon further research as to why this may be a necessity, I found that in order for the item to be completely sterile for use or discarding, the steam that's used to sterilize in the autoclave must come into full contact with what needs to be sterilized. Since air disrupts the steam circulation (which you did well by including in your article), the item would not be completely sterilized and thus diminishes the process of sterilization. Perhaps adding the importance of the removal of air in an autoclave would be very beneficial in this article.  Kkiing08 (talk) 02:09, 17 October 2022 (UTC)
