- Class 6–10 science: testing acids and bases with indicators and observing simple reactions.
- Class 11–12 salt analysis: preliminary and confirmatory tests for anions and cations.
- B.Sc. and diploma labs: micro-scale reactions that save reagents and reduce waste.
The name Test Piece is the catalogue term for this item; it is an ordinary laboratory test tube.
