reagents
Test tube ingredients
Reagents are substances used to produce chemical reactions, typically in laboratory settings.
A reagent may test for the presence of another substance, cause a transformation, or serve as a starting material in synthesis.
The term appears most often in chemistry, biology, and medical diagnostics: The lab ordered fresh reagents for the blood tests.
Reagent-grade chemicals meet purity standards for analytical work.
