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. To heat substances using electricity, not a flame.
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 Components Ring 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 Components Wire 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.

13. Crucible with lid: heat small samples

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

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

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

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

19. Disposable pipet
To drop small amount of liquids

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

21. Erlenmeyer flask
To hold liquids
NOT used to measure accurately

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

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

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

25. 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.

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

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

28. safety goggles
To protect eyes against burns or cuts

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

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

31. Well Plate: small scale reactions

32. 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!

33. 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.

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

35. 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

36. Wash Bottle
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
Distilled Water
NEVER squirt water at another student!!!

37. Eyewash Station
Push this handle to turn on the water – it will stay on until you pull it to turn off.
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 minutes!

38. 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.

39. 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.
