Presentation Transcript

  1. Scientific Lab Equipment

  2. graduated cylinder (graduate) • To measure volume of liquids accurately

  3. Metric Ruler • To measure the lengths of solid objects accurately

  4. oC thermometer • To measure temperature accurately

  5. magnifying glass (hand lens) • To make objects appear larger than they are

  6. Bunsen burner • To heat substances (with a flame)

  7. hot plate • To heat substances using electricity, not a flame.

  8. Lighter These strikers are used to light lab burners. The flints on strikers are expensive. Do not operate the striker repeatedly just to see the sparks!

  9. ring stand with clamp and ring • To hold containers away from a heat source (such as fire) during an experiment

  10. Ringstands and their ComponentsRing Clamp Ring clamps connect to a ringstand, and provide a stable, elevated platform for a beaker to be heated. Will also hold a clay triangle and funnel during filtering.

  11. Ringstands 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 was asbestos – currently it is a ceramic.

  12. Crucible with lid: heat small samples

  13. Crucible Triangle: Cradles crucible to secure over a flame

  14. Crucible Tongs For handling hot crucibles; also used to pick up other hot objects - NOT to be used for picking up beakers!

  15. test tube • To hold liquids and chemicals during experiments (investigations)

  16. test tube holder • To hold test tubes over heat or away from your body

  17. Disposable pipet • To drop small amount of liquids

  18. forceps • To pick up small items that you should not touch

  19. Erlenmeyer flask • To hold liquids • NOT used to measure accurately

  20. beaker • To hold, pour, or estimate liquids • NOT used to measure substances accurately

  21. Funnel To pour liquids from one container to another without spilling anything

  22. stirring rod • To mix chemicals and hot liquids together (like a spoon)

  23. The stirring rod is used to: a) manually stir solutions; b) assist in pouring liquids; and c) to transfer a single drop of a solution. Rubber policeman tip is used to remove precipitates. Stirring Rod Stir with this end.

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

  25. tongs • To pick up large objects that you should not touch (e.g., hot containers, flasks of acids, etc.)

  26. safety goggles • To protect eyes against burns or cuts

  27. test tube brush • To clean the insides of test tubes after investigations

  28. test tube rack • To hold test tubes during an investigation. (After cleaning, test tubes can be placed upside down to dry.)

  29. Well Plate: small scale reactions

  30. Broken Glass Box and Trash Can Broken Glass box to dispose of any broken glass, instead of the trash can. Trash Can to dispose of paper waste only!

  31. Watch Glass A watch glass is used to hold a small amount of solid, such as the product of a reaction. Can also be used as a cover for an evaporating dish or beaker.

  32. Evaporating Dish The evaporating dish is used for heating stable solid compounds and elements, as well as for evaporating nonvolatile solutions.

  33. Weighing Boat • Weighing boats are used to weigh solids that will be transferred to another vessel. • We will also use squares of paper for this purpose – throw them away after using. • Never put chemicals directly on the balance scale – it leaves residue and can harm the balance

  34. A wash bottle has a spout that delivers a water stream to a specific area. Distilled water is the only liquid that should be used in a wash bottle Wash Bottle Distilled Water NEVER squirt water at another student!!!

  35. Push this handle to turn on the water – it will stay on until you pull it to turn off. Eyewash Station The Eyewash is located in the back of the lab in my chemical closed and under the Safety Shower. You will need to summons me for assistance at the Eyewash Station. Flush your eyes for 15-20 minutes!

  36. Safety Shower Lots of water will come pouring out here to rinse chemicals spilled on you. This is the handle to pull to activate the safety shower.

  37. Eyewash Bottle and Fire Extinguisher Fire Extinguishers are found behind the door, at the door to my chemical room and at the back left corner of the lab stations.

  38. Lab Equipment-Review Uses.ppt Congratulations! Now that you’ve learned the names and uses of these pieces of lab equipment, you are almost ready to work in the laboratory!
