Science Lab Equipment 1 Triple Beam Balance or

Science Lab Equipment

1. Triple Beam Balance or Digital Scale • Measures the mass of substances or objects • Measures in grams

2. Graduated Cylinder • Accurately measures the volume of liquids The curved water line that occurs due to the attraction between water molecules and the glass walls of a graduated cylinder is called a meniscus • The graduated cylinder should be at eye level when reading the scale

3. Ruler, meterstick, or tape measure • Measures the lengths of objects. In science, we use the metric side of the ruler. • The numbers on the metric side represent centimeters.

4. Thermometer • M measures temperatures accurately • Celsius and Kelvin scales are used in science

5. Bunsen Burner • Used to heat substances (with a flame) • Hottest flame will appear blue

6. Hot Plate • Used to heat substances using electricity instead of a flame.

7. Ring Stand with Clamp and Ring • Holds containers away from a heat source during an experiment

8. Test Tube Holds small amounts of liquids and chemicals during experiments

9. Test Tube Holder Safely holds test tubes over heat or away from your body

10. test tube rack • Holds test tubes during an investigation. (After cleaning, test tubes can be placed upside down to dry. )

11. Stirring rods • As name implies • Used to mix chemicals and hot liquids together

12. Pipets and medicine droppers (eyedropper) Accurately measures and/or transfers small amounts of liquids

13. Forceps • Used to pick up small items

14. Florence flask • Round body • Used to hold liquids • Not used to measure accurately

15. Erlenmeyer flask • Flat bottom • Used to mix, heat and store liquids • Used in titrations • Not used to measure accurately

16. beaker • Used to hold, pour, or estimate liquids • Does not measure as accurately as a graduated cylinder or pipette • Measures in milliliters

17. Funnel Used to pour liquids from one container to another without spilling anything

18. Tongs Used to pick up large objects that you should not touch (e. g. , hot containers, flasks of acids, etc. )

19. Petri dish • Used to grow bacteria and other tiny living things • *Also used to hold small amounts of chemicals in order to find their mass.

20. litmus paper • Used to determine whether a liquid is an acid or a base

20. Mortar and Pestle Mortar Pestle • Used to crush and grind substance

Crucible • Used to heat small amounts of a chemical
