oxidatorn.

Brit.

/ˈɒksᵻdeɪtə/, U.S.

/ˈɑksəˌdeɪdər/

Forms: 1800s oxydator, 1800s– oxidator.

Origin: Formed within English, by derivation. Etymons: oxidate v., -or suffix.

Etymology: < oxidate v. + -or suffix.With the variation in form compare oxide n. and discussion at that entry.

Chiefly Chemistry.

1. A device for directing a stream of oxygen into a reaction vessel or (in early use) the flame of a lamp; an apparatus for oxidizing a substance, esp. for purposes of analysis.
