Transcript of "Lab equipment"

  1. 1. Lab Equipment
  2. 2. BeakerBeakers hold solids orliquids that will notrelease gases whenreacted or are unlikelyto splatter if stirred orheated.
  3. 3. 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.
  4. 4. Florence FlaskRarely used in first year chemistry, it isused for the mixing of chemicals.Narrow neck prevents splash exposure.
  5. 5. Graduated CylinderA graduatedcylinder is used tomeasure volumes ofliquids.
  6. 6. Petri DishUsed to growbacteria or othermicrobes
  7. 7. Test Tubes 13 x 100 mm test tubesIgnition tube 10 x 75 mm test tubes
  8. 8. Test Tube HolderA test tube holder isuseful for holding atest tube which is toohot to handle.
  9. 9. Test Tube BrushesTest tube brushes areused to clean test tubesand graduated cylinders.Forcing a large brush into asmall test tube will oftenbreak the tube.
  10. 10. Test Tube RacksTest tube racks are for holding and organizing testtubes on the laboratory counter. Plastic racks maymelt in contact with very hot test tubes.
  11. 11. 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.
  12. 12. Spot PlatesSpot plates are used whenwe want to perform manysmall scale reactions at onetime.
  13. 13. Watch GlassA watch glass is used tohold a small amount ofsolid, such as theproduct of a reaction.
  14. 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. 15. 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”
  16. 16. PipetteSimilar tomedicinedroppers, butare designedfor moreaccuracy andprecision
  17. 17. ForcepsForceps (or tweezers) are used to pick up smallobjects.
  18. 18. Barnes Bottle with Dropper Used to dispense and store a variety of liquids
  19. 19. Light Microscope Used to obtain an enlarged image of small objects and reveal details of structure not otherwise distinguishable.
  20. 20. Microscope Slide Used to hold objects for inspection under the microscope
  21. 21. Cover Slip Placed over objects on a microscope slide to hold them in place
  22. 22. Lens TissueLint-less wipes used to cleanmicroscope lenses and slides
  23. 23. SpatulasSpatulas are used to dispense solidchemicals from their containers.Chemicals should never be transferredwith your bare hands.
  24. 24. Beaker Tongs Beaker tongs are used to move beakers containing hot liquids
  25. 25. Bunsen Burner Bunsen burners are used for the heating of nonvolatile liquids and solids.
  26. 26. Ringstands and their ComponentsRingstands are a safe andconvenient way to performreactions that require heatingusing a Bunsen burner.
  27. 27. Ringstands and their Components Iron RingsIron rings connect to aringstand and provide astable, elevated platformfor the reaction.
  28. 28. Ringstands and their Components Utility ClampsUtility clamps are used tosecure testtubes, distillationcolumns, and burets to theringstand.
  29. 29. Ringstands and their Components Wire GauzeWire gauze sits on the ironring to provide a place tostand a beaker.On older wire gauze, the white material isasbestos!
  30. 30. Pressed Fiber PadA 4” x 4” square of ceramicfiber, it provides a surface forhot beakers so that the beakerdoes not come in contact witha cold countertop and shatter.
  31. 31. StrikersStrikers are used to lightBunsen burners.The flints on strikers areexpensive. Do not operatethe striker repeatedly justto see the sparks!
  32. 32. Hot Plate Hot plates are generally used to heat glassware or its contents.
  33. 33. Dissecting InstrumentsDissecting Scissors Scalpel
  34. 34. Safety Gear
  35. 35. Consider the following…• A new strain of bacteria thought to cause senioritis has been found in the HHS pool. The gym teachers suspect that the bacteria growth is effected by the temperature of the water.• Design an experiment that would test this hypothesis. Be sure to list all the steps you would make and include materials you would need.
  1. A particular slide catching your eye?

    Clipping is a handy way to collect important slides you want to go back to later.
