Introduction to Chemistry: Apparatus Used in Heating

1. Test Tube
It is a narrow/thin glass apparatus open on one side

2. Boiling tube
It is a wide glass apparatus, bigger than a test tube and open on one side

3. Beaker
A beaker is a wide calibrated/graduated lipped glass/plastic apparatus used for transferring liquid solution which do not normally require very accurate measurements

4. Conical flask
A conical flask is a moderately narrow glass apparatus with a wide base and no calibration/graduation. The narrow mouth ensures no spillage

5. Round bottomed flask
A moderately narrow glass apparatus with a wide round base and no calibration/graduation. It must be held/ clamped when in use because of its wide narrow base.

6. Flat bottomed flask
It is a moderately narrow glass apparatus with a wide round base with a small flat bottom.

7. Tripod Stand and Wire gauze
A tripod stand is a three legged metallic apparatus which unstable apparatus are placed on during heating. Wire gauze is a metallic/iron plate of wires crossings. It is placed on top of a tripod stand.

8. Clamp stand
It is a metallic apparatus which tightly hold apparatus at their “neck” firmly, it has a wide base that increases stability

9. Test tube holder
It is a hand held metallic apparatus which tightly holds a test/boiling/ignition tube firmly during heating.
