  1. Lab Equipment

  2. Gloves Safety First

  3. Fume Hood

  4. Beakers • Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated. • Beakers are not used for measuring because they have poor accuracy

  5. Beaker Tongs Beaker tongs are used to move beakers containing hot liquids

  6. Erlenmeyer Flask Erlenmeyer flasks hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.

  7. Graduated Cylinder A graduated cylinder is used to measure volumes of liquids.

  8. Test Tubes 13 x 100 mm test tubes Ignition tube 10 x 75 mm test tubes

  9. Test Tube Holder A test tube holder is useful for holding a test tube which is too hot to handle.

  10. Test Tube Brushes Test tube brushes are used to clean test tubes and graduated cylinders. Forcing a large brush into a small test tube will often break the tube.

  11. Test Tube Racks Test tube racks are for holding and organizing test tubes on the laboratory counter. Plastic racks may melt in contact with very hot test tubes.

  12. Rubber Stoppers Rubber stoppers are used to close containers to avoid spillage or contamination. Containers should never be heated when there is a stopper in place.

  13. Watch Glass A watch glass is used to hold a small amount of solid, such as the product of a reaction.

  14. Glass Stir Rod A glass rod is used to manually stir solutions. It can also be used to transfer a single drop of a solution.

  15. Litmus Paper Redlitmus paper is used to identify bases. Bluelitmus paper is used to identify acids.

  16. Forceps Forceps (or tweezers) are used to pick up small objects.

  17. Funnel A funnel is used to aid in the transfer of liquids from one vessel to another.

  18. Mohr Pipette A Mohr pipette measures and delivers exact volumes of liquids.

  19. Weighing Boat Weighing boats are used to weigh solids that will be transferred to another vessel. NEVER put chemicals directly on the balance

  20. Spatulas Spatulas are used to dispense solid chemicals from their containers. Chemicals should never be transferred with your bare hands.

  21. Bunsen Burner Bunsen burners are used for the heating of nonvolatile liquids and solids.

  22. Strikers Strikers are used to light Bunsen burners. The flints on strikers are expensive. Do not operate the striker repeatedly just to see the sparks!

  23. Hot Plate • Used to heat things

  24. Evaporating Dish The evaporating dish is used for the heating of stable solid compounds and elements.

  25. Clay Triangle The clay triangle is used as a support for porcelain crucibles when being heated over a Bunsen burner.

  26. Ring stands and their Components Ring stands are a safe and convenient way to perform reactions that require heating using a Bunsen burner.

  27. Ring stands and their ComponentsIron Rings Iron rings connect to a ring stand and provide a stable, elevated platform for the reaction.

  28. Ring stands and their ComponentsUtility Clamps Utility clamps are used to secure test tubes, distillation columns, and burettes to the ring stand.

  29. Ring stands and their ComponentsDouble Burette Clamps Double Burette clamps are used to burettes – long graduated tubes used in titration.

  30. Ring stands and their ComponentsWire Gauze Wire gauze sits on the iron ring to provide a place to stand a beaker. On older wire gauze, the white material is asbestos!

  31. Thermometer Never Shake a thermometer Never put a thermometry directly into a flame

  32. Disposable Pipette Transfers liquids Its disposable

  33. Medicine Dropper A medicine dropper is used to transfer a small volume of liquid (less than one mL). On top of each medicine dropper is a “rubber bulb”

  34. Wash Bottle A wash bottle has a spout that delivers a wash solution to a specific area. Distilled water is the only liquid that should be used in a wash bottle.

  35. Electronic Balance • Using the Electronic Balance Scale • Obtain the chemical. • Turn the balance ON. • Place an empty weighing boat on the balance. • Press TARE. • (the balance will now read “0”) • Carefully add the chemical. • Using a spatuala • When you are done, press OFF. • Clean up any spills around the balance and on the table top.
