Talk:Petri dish

Petri

A Petri dish is a shallow glass or plastic cylindrical dish that biologists use to culture microbes. It was named after the German bacteriologist Mr.Petri (1785-1925) This should say "Julius Richard Petri" http://wiki.riteme.site/wiki/Julius_Richard_Petri

Well spotted – someone changed it from Julius earlier today. Feel free to be bold and correct such errors yourself. Adrian J. Hunter^{(talk•contribs)} 08:09, 23 January 2009 (UTC)[reply]

who invented it in 1877 when working as an assistant to Richard Koch.

This should say "Robert" Koch - not Richard. 172.184.43.66 06:04, 15 January 2006 (UTC)[reply]

Capitalization

I took a quick scan of some online dictionaries. Most of them do not capitalize "petri dish". chouhouzi 14:17, 10 DEC 2008

Most paper dictionaries do not capitalize either, nor is capitalization the common usage in scientific writing. The article has been fixed. Piperh (talk) 19:29, 12 July 2009 (UTC)[reply]

Petri should not contain a capital P. If you read scientific texts it will usually be capitalised. Search Pubmed or something for an article containing Petri dishes for examples, it's pretty much universally capital P.

Just a quick addition to this discusson. I am publishing a book with MIT Press and the editors changed it to lower case P, even though that still seems weird to me. FWIW. --Jyoshimi (talk) 17:42, 12 April 2024 (UTC)[reply]

choice of pictures

although both of the pictures included are visuably appealing, i'm not sure that they are encyclopedaic enough, as neither clearly shows the standard laboratory usage of petri dishes (especially the one on the left) —The preceding unsigned comment was added by 71.112.109.133 (talk • contribs) .

Removed the bioluminescence image, which is licensed non-commercial-use-only anyway. Femto 13:28, 8 February 2006 (UTC)[reply]

Although the current picture is nice, it could be confusing for someone who doesn't know what a Petri dish is. If you ask me, I'll tell you that by looking a the picture it looks like circular floating extraterrestrial beings. 165.123.140.215 10:01, 14 February 2006 (UTC)[reply]

Replaced with another one that was available from Wikimedia Commons. Femto 14:22, 14 February 2006 (UTC)[reply]

Syracuse dish

Anyone know what a Syracuse dish is? Is it the same as a petri dish? See these Google results [1]. -newkai t-c 22:34, 10 February 2007 (UTC)[reply]

According to Merriam-Webster: Syracuse watch glass, Syracuse dish: a small circular flat-bottomed dish of thick glass with a shallow depression used in biology (as for staining, culturing, and various phases of microtechnic).

Here's a decent photo from a supplier [2]. Looks quite different, so here's a new stub: Syracuse dish. Femto 15:35, 11 February 2007 (UTC)[reply]

Spamming Wikipedia

Biologicalworld.com has spammed wikipedia like no tomorrow. He is a site of only a few pages and a LOT of adsense. Not much information is given except for "protocols" which are not referenced, and cannot be trusted from a site of that quality.

Microscopes

Can Petri dishes be used under microscopes? I had heard that they could not be, but not from a reliable source. Does anyone know? Raptortech97 (talk) 21:28, 31 May 2010 (UTC)[reply]

It just depends on the type of microscope. I routinely put plates under a disecting microscope to look at colony morphology. It depends on where the light comes from. Very few (if any) microscopes that require light to be shined through a sample will work with a petri plate. But scopes that shine light onto a sample from the same side as the lens might work. Adenosine ^talk 01:03, 1 June 2010 (UTC)[reply]

I agree with user:Adenosine about the positioning of the light source being important. However, Petri dishes are sometimes used for mammalian cell culture as an alternative to tissue culture flasks. In that case the cells can be viewed using an Inverted microscope. Of course these dishes don't contain any agar which is one of the things that prevents you from using the same technique on a standard bacterial culture plate.

Pronounication

Hi, can someone confirm whether it is peetri or pet ree ? Wakelamp (talk) 02:52, 31 May 2013 (UTC)[reply]

It is pet-ri (ree). ^[1]
