Bunsen burner 4. clay triangle 5. crucible & cover 6. crucible tongs 7. dropper pipet 8. Erlenm eyer flask 9. evaporating dish 10. forceps/tweezers 11. funnel used to hold solids or liquids that are heated or reacted 12. glass stirring rod used to hold solids or liquids that react without heating or react with gentle heating used to manually stir solutions or transfer a single drop of a solution 13. graduated cylinder 14. iron ring 15. mortar & pestle used to measure temperature 16. ring stand 17. safety goggles 18. scoopula 19. spot plate 20. test tube rack 21. test tube holder 22. test tubes 23. test tube brushes 24. thermometer 25. triangular file 26. utility clamp 27. wash bottle 28. watch glass 29. weighing dish 30. wire brush 31. wire gauze used to clean test tubes and graduated cylinders (make sure to use the right size) has a spout that delivers a wash solution to a specific area (should contain water ONLY) used to transfer a small volume of liquid (has a rubber bulb at one end) used to aid in the transfer of a liquid from one container to another, or the filtering of a solid from a lqiud used to secure test tubes, and Erlenmeyer flasks to the ring stand used to heat certain solids to very high temperatures used to support a crucible when it is being heated wtih a Bunsen burner used to perform many small scale reactions at one time used to pick up small objects used to ground up solids into fine powders used primarily to cut glass tubing used to protect your eyes during an experiment used to handle beakers containing hot liquids (they are NOT to be used to move crucibles) used to handle hot crucibles or other hot objects (they are NOT to be used to move beakers) used to hold a test tube which is too hot to handle used to dispense solid chemicals from their containers (NEVER use your bare hands) used to heat solid compounds and elements used to hold a small amount of solid or to cover a container in which a reaction is occurring used to weigh solids that will be transferred to another container
