This document lists and describes common laboratory apparatuses and their uses. It explains that performing experiments accurately requires using the proper tools. Some of the key apparatuses it outlines include test tubes for holding small liquid samples, beakers for measuring and heating liquids, alcohol lamps for heating substances, thermometers for measuring temperature, stirring rods for mixing compounds, and spatulas, watch glasses, crucibles and funnels for transferring or containing samples. Understanding how to use these various instruments is important for studying science.

APPARATUSES

2. LABORATORY APPARATUSES
Performing activities and experiments
becomes accurate when tools and
apparatuses are used. Being familiar with
these instruments and knowing how to use
them are of great advantage in the study of
science.

3. HERE ARE SOME
LABORATORY
APPARATUSES
AND THEIR USES:

4. Test Tube
- holds small
amount of liquid and
is used for
observation.

5. Beaker
- holds and
measures the
amount of liquid and
used also for
heating.

6. Test Tube Rack
- holds test tube to
avoid breaking;
used for
observation
purposes.

7. Alcohol Lamp
- heats or boil
liquid under study.

8. Laboratory
Thermometer
- measures the
coldness and
hotness of objects.

9. Test Tube Holder
- holds test tube
during heating.

10. Iron Stand
- supports objects
to be heated.

11. Stirring Rod
- is used to stir or
mix mixtures and
compounds.

12. Spatula
- is used to
transfer powdered
chemicals to avoil
contamination.

13. Watch Glass
- holds small
amount of liquids
or powder under
observation.

14. Wire Gauze
- spreads the heat
of the burner and
prevents the
breaking of the
objects being
heated.

15. Crucible and Cover
- are used to hold
chemicals and
powder to be
heated.

16. Mortar and Pestle
- are used to grind
and crush
chemicals into
finer texture; also
used for mixing.

17. Glass Funnel
- transfers liquids
from one container
to another.
