1. Laboratory Equipment
And Safety

2. Beakers Measures the volume of liquids
Not as precise as using a graduated cylinder
Many different sizes
Good for holding and mixing substances

3. Erlenmeyer flask Measures the volume of liquids
Not as precise as a graduated cylinder
Has narrow top so you can use a rubber stopper in it, to avoid splashing or breathing in fumes

4. Graduated cylinder Measures liquids very accurately
Read the bottom of the meniscus when reading the volume of a liquid

5. Dissecting equipment Dissecting tray (pan to dissect in)
Pins (hold down the specimen)
Dissecting probe
(used to separate tissues)
Scalpel (used for cutting tissues)
Dissecting scissors (used for cutting)
Forceps (NOT tweezers)(used for grasping or tearing tissues)

6. Microscope equipment Microscope Microscope slides Coverslips
Depression slide (has a depression in which you can put liquids)

7. Innoculating loop
Used to transfer a tiny bit of liquid from one test tube to another
Used primarily for transferring bacteria
The loop is made of wire which can be sterilized in a bunsen burner (it turns red hot)

8. Test tube equipment Rack (holds test tubes)
Test tubes (hold substances for heating in burners, or for mixing)
Rubber stoppers (made of black rubber) and corks (made of wood)
Test tube holders (hold hot test tubes safely)
Test tube brush (cleans test tubes)

9. Tongs May or may not have rubber ends for holding hot beakers
Used to pick up substances that may be hot or have chemicals on them
beaker tongs

10. Petri dish
Used to hold liquids, grow bacteria, or hold solid substances

11. dropper
Used to transfer liquids one drop at a time (glass with rubber tip)
Disposable pipette (all plastic)

12. Safety goggles (or glasses)
Protect the eyes from chemical splashes, burning liquids, or other dangers in the laboratory

13. Hand lens
Magnifies objects to be seen more easily

14. Funnel
Helps you pour liquids from one container to another

15. Watch glass Covers beakers to prevent evaporation or contamination
Can also be used to hold substances

16. Burner equipment
Burner or “Bunsen burner” has a flame for heating substances
Striker has flint in it, for starting the flame
Orange rubber tubing carries gas from the gas jets to the burner

17. Ring stand setup
Ring stand
Wire gauze
Metal ring
Burner

18. Thermometer Measures temperature Red inside is an alcohol thermometer
Metallic (silver) inside is mercury

19. Stirring rod Stirs substances
Never, ever, ever use a thermometer to stir!

20. Hot plate
For heating substances

21. Mortar and pestle
Used to grind up solids into powder

22. Ruler
Used to measure length
