1. Laboratory Equipment and Safety

2. Beaker Used to measure large quantities of liquids
Read at eye level and at the bottom of the meniscus

3. What is a meniscus? The line formed by a liquid in glassware
The wider the glassware the thinner the meniscus
Read liquid levels from the bottom of the meniscus

4. Graduated Cylinder Used to measure small quantities of liquids
Used when quantities need to be precise
Read at eye level and at the bottom of the meniscus

5. Volumetric Flask
Used when reactants must be measured extremely precisely
Add solid reactant first then fill to the line with liquid reactant
Read at eye level and at the bottom of the meniscus

6. Erlenmeyer Flask Used for carrying out experiment
Never used for measuring liquids
Never fill more than half way

7. Test Tube/Test Tube Rack
Used to conduct an experiment using small quantities of reactants
Are to remain in the test tube rack during experimentation

8. Triple Beam Balance Used to mass solid reactants
Must be tarred prior to use
Always use weigh paper; never place reactants directly on the plate

9. Hot Plate Used to heat liquids
Never fill glassware more than half way when heating
If a solid needs to be heated…
Heat water in a large beaker
Place the solid in a test tube
Place the test tube in the large beaker

10. Microscope
Used to look at very small objects

11. Laboratory Attire All students must wear:
Goggles
Apron
Gloves
All long hair or loose clothing must be secured prior to the start of lab

12. Safety Equipment Emergency shower Eye wash station First aid cabinet
Used if chemicals get on large portions of your skin or clothing
Eye wash station
Used if chemicals get into your eyes
Hold eyes open in stream of water until otherwise instructed by the teacher or nurse
First aid cabinet
Contains basic first aid supplies for minor injuries

13. Safety Equipment (cont’d)
Fire extinguisher
Used to put out fires on objects, not people
To use:
Pull the pin
Aim nozzle at the base of the fire
Squeeze the handle

14. Important Notes
Always inform a teacher of an injury or accident immediately
Allow the teachers to perform any necessary first aid
In the event of an emergency, follow all directions the first time they are given
