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

  2. Beaker • 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. Forceps • Used to hold or pick up small items

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

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

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

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

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

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

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

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

  15. Hot Plate • Used to heat substances.

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

  17. 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.

  18. 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.

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

  20. Crucible Tongs • Used to carry crucible.

  21. Beaker Tongs • Used to carry beakers.

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

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

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

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

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

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

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

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

  30. Pipet • Used to precisely measure the volume of liquids in small amounts.
