2. Beakers are used for stirring, mixing, or heating liquids
Beakers are used for stirring, mixing, or heating liquids. Beakers are graduated (have marks on the side to measure volume) but they’re not intended to be used to accurately measure volume.
Beaker

3. The crucible is small porcelain container used to heat substances to very high temperatures.

4. Crucible tongs hold crucibles only
Crucible tongs hold crucibles only. They have long handles and the tips are serrated to give a better grip.

5. Pipets come in various sizes and are used to transport accurate volumes of liquids. Pipettes must be used with a pipet bulb to draw the liquid in.
Never use your mouth to pull the liquid in the pipet!

6. Pipet bulbs are used to draw liquids into the pipet.

7. Droppers are used to transfer small volumes of liquids.

8. A watch glass is used as a surface to evaporate liquids, to hold solids that are being weighed, or to cover beakers.

9. Erlenmeyer flasks are used to mix, heat, and store liquids
Erlenmeyer flasks are used to mix, heat, and store liquids. These flasks are not used to accurately measure volumes of liquids.

10. Round bottom flask or Florence flask
Round bottom flasks or Florence flasks are used to uniformly heat and boil liquids.

11. Test tubes are used to hold, mix or heat very small amounts of solids or liquids.

12. Graduated cylinders are used to measure volumes
Graduated cylinders are used to measure volumes. To accurately read the volume of a liquid, read the bottom of the meniscus.

13. A glass funnel is used to channel liquids into containers that have small openings.

14. A buret is used to dispense accurate volumes of liquids.

15. A test tube holder is used to hold a test tube when it’s hot or when it’s not safe to use the hands.

16. Test tube brushes are used to clean test tubes and graduated cylinders.

17. Glass stirring rods are used to stir solutions
Glass stirring rods are used to stir solutions. Stirring rods are also used to decant, a method that separates a liquid from a solid. Decanting is slowly pouring a liquid down a stirring rod, leaving the solid in the beaker.

18. Forceps are used to pick up small items.

19. Litmus paper is an indicator that tells us whether a solution is acidic, basic, or neutral.

20. Ring stands provide a safe base to hold and clamp glassware and pieces of lab equipment.

21. Utility clamps are attached to a ring stand to hold test tubes, pH probes, burets, and other pieces of lab equipment.

22. A ring clamp is attached to the ring stand to support and hold glassware such as crucibles, beakers and Erlenmeyer flasks.

23. Test tube racks hold and help organize test tubes during experiments.

24. A Bunsen burner is used to heat solutions and other chemicals in the lab.

25. Volumetric flasks are used to make and dilute solutions to specific concentrations.

26. The wash bottle is used in the clean up phase of an experiment
The wash bottle is used in the clean up phase of an experiment. Usually in a general chemistry lab you only put deionized water even though you can have other solvents.

27. The wire gauze is placed over the ring clamp to support beakers and flasks over a flame.

28. A bowl made of ceramic to crush and grind solis.
Mortar and pestle

29. Utensil used in chemistry to transfer solids.
