This document describes various pieces of lab equipment and their uses. Beakers, conical flasks, test tubes, test tube holders, tripod stands, Bunsen burners, wire mesh or gauze are used for holding, mixing, heating substances. Digital balances accurately measure mass up to 200g, measuring cylinders and burettes precisely measure volumes, pipettes measure small volumes of liquids. Funnels transfer substances between containers, evaporating dishes remove excess liquids, thermometers measure temperature, and beaker tongs and wash bottles are also used.

1. Lab Equipment

2. Beakers
• Beakers are used
for holding and
mixing various
chemicals.
• Not for measuring
precisely.
• Sizes vary.

3. Conical Flask
• Used to hold, mix
and approximately
measure the
volume various
liquids.
• Useful for mixing
• Sizes vary.

4. Test Tubes and Rack
• Racks are used to
hold tubes while
experimenting.
• Test tubes are used
to hold, mix or heat
the chemical during
reaction
• Not for measuring
precisely.
• Sizes vary.

5. Test Tube Holder
• Used for carrying
or holding hot test
tubes.

6. Digital Balance
• Used to accurately
measure mass.
• Only up to 200g in
our labs.

7. Tripod Stand
• To support apparatus
during heating

8. Bunsen Burner
• Used to heat
substances quickly
or if > 400oC is
needed.
• Do not use with
flammable
substances.

9. Wire Mesh or Gauze
• Used to absorb
and spread the
heat of flame.
• Keeps glassware
from cracking and
breaking.

10. Measuring Cylinder
• Used to precisely
measure the volume
of liquids or run
experiments.
• Sizes vary.

11. Burette
• Used for precisely
measuring
dispensed liquids.
• Accurate way of
measuring volume.

12. Pipette
• Used to precisely
measure the
volume of liquids in
small amounts.

13. Dropper and Bottle
• Used to measure
out small amounts
of liquids for
experiments.

14. Funnel
• Used to safely
transfer
substances from
one container to
another.

15. Evaporating Dish
• Used to
evaporate
excess liquids.

16. Thermometer
• Measuring
temperature.

17. Beaker Tongs
• Used to carry
beakers.

18. Wash Bottle
• Usually contains
distilled water.
