Applications and Experiments for the 12 x 100 mm Test Tube
A 12 x 100 mm test tube is used for small-volume tests where only a little of each chemical is needed. It is well suited to salt analysis, indicator tests and quick reactions in CBSE/NCERT Class 6–12 science, B.Sc. qualitative analysis and micro-scale chemistry practicals.
- Class 6–10 science: testing acids and bases with Universal Ph Indicator paper and observing simple reactions.
- Class 11–12 salt analysis: preliminary and confirmatory tests for anions and cations, adding reagents from a Glass Bottle, with Dropper 60ml.
- B.Sc. and diploma labs: micro-scale reactions that save reagents and reduce waste, with the tube gripped in a Test Tube Holder with Handle when warmed.
The name Test Piece is the catalogue term for this item; it is an ordinary laboratory test tube.

Who supplies this test tube?
Ambala-based Science Lab Supplies is the supplier, quoting schools, colleges, contractors and distributors directly for test tubes and the rest of their laboratory glassware on a single quotation.
Can the tube be heated?
Yes, the glass is heat resistant. Hold the tube with a holder, warm it gently while moving it in the flame, and point the mouth away from yourself and others.
