Lab equipments and their Uses lesson for grade 7

1. Common Laboratory
tools
{
Their uses.

2. These are containers that are
used to hold and heat liquids.
It performs a multipurpose
and essential purpose in the
lab.
Beaker

3. This is for holding hot solid
objects.
They are used for holding many
different things such as flasks,
crucibles, and dishes when they
are hot.
Crucible tong

4. Test tube brushes are used for easily
cleaning the inner parts of a test tube

5. This is used to contain substances for
testing .
This glass is also to hold solids for weighing
but not for heating.
Glass Plates

6. A wire gauze is used to
support beakers or flasks
when heating.
Wire Gauze

7. Used to measure volume of liquids
Graduated cylinder

8. A mortar and pestle are used for
breaking/crushing solid
substances into smaller particles/
powder. This enables the solid
dissolve better.
Mortar and pestle

9. Dropper is used in transferring
small amount of liquid and for
dropping liquid into another
substance.
Dropper

10. This is used to hold large
amount of liquid and to heat and
store liquids. The advantage the
Erlenmeyer Flask has is that the
bottom is wider than the top so it
will heat quicker because of the
greater surface area exposed to
the heat.

11. A funnel is used to support filter
paper during filtration and for
pouring liquids into containers with
small mouth or opening
Funnel

12. The stir rods are used for stirring or
mixing solutions. They are usually
made of glass. Stir Rods are very
useful in the lab setting.

13. Graduated cylinder Used to
measure volume of liquids

14. Iron stand and clamp holder is used
as a support when assembling a set
up.

15. Test tube Container for small amount of
liquid and solid substances for testing or
heating.
Test Tube

16. Stopper is used to seal a container like
Erlenmeyer flask and Florence flask.
Stoppers come in many different sizes.
The sizes are from 0 to 8. Stoppers can
have holes for thermometers and f
or other probes that may be used.

17. Test tube rack For drying test tubes
and holding while observing chemical
reactions The test tube rack is used to
hold test tubes while reactions
happen in them or while they are not
needed.
Test tube rack

18. Test tube holder For holding test
tubes when heating contents The
holder is used to hold test tubes
when they are hot and untouchable.

19. Laboratory thermometer To measure
temperature of substances The
thermometer is used to take
temperature of solids, liquids, and
gases. They are usually in o C , but
can also be in o F

20. 
This is used to support equipment
or apparatus for heating purposes
which need not attached
Tripod

21. Watch glass To contain substances for
analysis or testing The watch glass is
used to hold solids when being
weighed or transported. They should
never be heated.
Watch glass

22. Volumetric flask isusedTo prepare
and to contain standard solutions The
Volumetric flask is used to measure
one specific volume. They are mostly
used in mixing solutions where a one
liter or one half a liter is needed.
Volumetric flask

23.  Spatula Used to transfer small amount of
solid/powdered chemicals
Spatula

24. Wash bottle Used to wash out solid
particles during filtration and for
washing narrow-mouthed containers
wash bottle

25. Pipette is used to transfer liquid
solution by suction.
Pipette

26. Florence flask Used to contain solution
The Florence Flask is used for heating
substances that need to be heated evenly.
The bulbed bottom allows the heat to
distribute through the liquid more evenly.
The Florence Flask is mostly used in
distillation experiments.
Florence flask

27. These are used for heating and
exposing items to flame. They have
many more uses than a hot plate, but
do not replace a hot plate.
Bunsen burner
