  1. Lab Equipment Visuals, Spellings, and Uses The Right tool for the job!

  2. Beakers • Beakers are used for holding various chemicals. • Not for measuring precisely. • Sizes vary.

  3. Graduated Cylinder • Used to precisely measure the volume of liquids or run experiments. • Read from the meniscus at eye level. • Plastic ring always on top if applicable. • Sizes vary.

  4. Erlenmeyer Flask • Used to approximately measure the volume various liquids. • Useful for mixing by swirling • Sizes vary.

  5. Florence Flask • Used to boil liquids. • Also used to collect gases, if applicable. • Sizes vary.

  6. Volumetric Flask • Used to prepare precise standard solutions. • They are only good for 1 specific volume. • Comes in many sizes

  7. Reagent Bottle • Used to store, transport, or view reagents such as acids or bases.

  8. Rubber Stoppers • Used to close flasks and test tubes. • The holes allow the insertion of glass tubing, probes, or thermometers as needed by the experiment.

  9. Test Tubes and Rack • Used to hold chemicals/tubes while experimenting. • Not for measuring precisely. • Waft! • Aim away from faces. • Sizes vary. • Label tubes.

  10. Distillation Flask • Used to separate liquids based on boiling point.

  11. Buret and Buret Clamp • Used for precisely measuring dispensed liquids • Holds buret to ring stand. Buret Double buret clamp Single buret clamp

  12. Ring Stand and Ring Clamps • Base/Pole of set-up for experimenting. • Holds glassware in place for heating or evaporating.

  13. Test Tube Brushes • Cleaning. • You must clean tubes before and after you use.

  14. Test Tube Holder • Used for carrying or holding hot test tubes.

  15. Thermometer • Measuring temperature. • Use metric!!

  16. Hot Plate • Used to heat substances.

  17. Bunsen Burner • Used to heat substances quickly or if > 400oC is needed. • Do not use with flammable substances.

  18. Rubber Tubing • Used for a variety of things. • Example: • Connecting Bunsen burner to gas valve stem. • Connecting glass tubing together.

  19. Wire Mesh or Gauze • Used to absorb and spread the heat of flame. • Keeps glassware from cracking and breaking. • Part of ring stand set-up.

  20. Clay Triangle • Used to hold a crucible in place on a ring stand. • Also helps absorb and spread heat of flame. • Part of ring stand set-up.

  21. Crucible and Cover • Used for heating substances. • Can withstand high direct heat.

  22. Crucible Tongs • Used to carry crucible.

  23. Beaker Tongs • Used to carry beakers.

  24. Mortar and Pestle • Used to grind substances into powder or slurry.

  25. Scoopula • Used to scoop chemical powders. • Not a measuring instrument. • Ours do not have handles.

  26. Stirring Rods • Used to stir substances. • Clean in between uses.

  27. Striker • Used to ignite gas from a Bunsen burner. • Do not waste flint.

  28. Watch Glass • Used to show chemical reactions.

  29. Evaporating Dish • Used to evaporate excess liquids.

  30. Centrifuge • Used to separate suspensions (solids from liquids).

  31. Meter Stick • Used to precisely measure length. • 1m = 10dm • 1m = 100cm • 1m = 1000mm

  32. Funnel • Used to safely transfer substances from one container to another.

  33. Dropper and Bottle • Used to measure out small amounts of liquids for experiments.

  34. Wash Bottle • Usually contains deionized water. • Handy for rinsing glassware and for dispensing small amounts of dH2O for chemical reactions.

  35. Goggles and Apron • Used to protect your eyes and clothing from damage. • These are a must in lab!!

  36. Inoculating or Flame Loop • Used to collect samples from colonies (ex. Bacteria) • Also used to test the spectra of chemicals.

  37. Digital Balance • Used to accurately measure mass. • Only up to 200g in our labs.

  38. Triple Beam Balance • Measures the mass of an object. • Make certain the balance is calibrated correctly before use.

  39. Double Pan Balance • Used to compare the masses of two substances.

  40. Centigram Balance • Used to precisely measure the mass of a substance. • More precise than the triple beam balance.

  41. Pipet, Pump, and Bulb • Used to precisely measure the volume of liquids in small amounts.

  42. Berol Pipet • Disposable pipets used to transfer small amounts of chemicals. • Graduated pipets can precisely measure small amounts of chemicals.

  43. Capillary Tubes • Used to collect liquid through the process of capillary action.
