Volume

[edit]

How about giving a guide as to its volume?

Both boiling tube and ignition tube have been merged and set as redirects. /Tpdwkouaa (talk) 22:05, 12 June 2020 (UTC)[reply]

I am confused. The section talks about boiling tubes, suddenly switches from plural to singular (before returning to plural), then mentions the difficulty of cleaning ignition tubes without defining, describing or distinguishing them. They are both variants of test tubes, but they both need adequate description by someone more knowledgeable than me: size (?volume) and function. Thanks.

The sub-section title of ignition tubes was removed by an anon user in 2020. Undid that change. Jay (Talk) 06:10, 17 September 2021 (UTC)[reply]
