  1. Common Chemistry Lab Equipment

  2. Chemistry Lab Drawer • Well Plate • Used for “small scale” reactions, where you are only using drops of solutions.

  3. Chemistry Lab Drawer • Micro Spatula and Scoopula • Used for measuring small amounts of chemicals.

  4. Scoops and Spoons • Never stick these directly into a bottle of chemicals. • You can contaminate the entire bottle. • This means that I will either have to throw it away, or your lab results could be affected.

  5. Chemistry Lab Drawer • Wash bottle. Use this for “rinsing” chemicals into your reaction vessel.

  6. Chemistry Lab Drawer • Test Tube Rack and Test Tubes • Test Tubes are another “primary” reaction vessel

  7. Chemistry Lab Drawer • Graduated Cylinder

  8. Graduated Cylinders • Use these to accurately measure liquids in lab. Never use beakers to measure. • The answer on the SOL to this question is always GRADUATED CYLINDER. • Accurate to within ± 0.05 ml. (This is ½ of the smallest division line on the cylinder.) Scientists call this the “uncertainty” of the measurement.

  9. Volumes. • We will work with liters (L) and milliliters (mL) in this class. • You should know that 1000 mL = 1L. • Also know that cubic centimeters (cm3) and milliliters (mL) are different names for the same amount. So, 1 mL = 1 cm3. • 1 drop from a dropper is approximately 0.05 mL. So, 20 drops = 1 mL.

  10. Chemistry Lab Drawer • Medicine droppers • We will primarily use plastic, disposable droppers.

  11. Chemistry Lab Drawer • Test Tube Holder

  12. Chemistry Lab Drawer • Thermometers

  13. Chemistry Lab Table • Crucible Tongs

  14. Chemistry Lab Drawer • Crucible and Lid • Used for STRONG Heating

  15. Chemistry Lab Drawer • Watch Glass

  16. Chemistry Lab Drawer • Glass Funnel • Used with filter paper.

  17. Chemistry Lab Drawer • Beakers

  18. Chemistry Lab Drawer • Evaporating Dish • Used for GENTLE heating or NO heating

  19. Chemistry Lab Drawer • Wire Triangle with Porcelain • Use this when heating crucibles.

  20. Chemistry Lab Drawer • Ring Stand and Clamps • Ring Clamps and Utility Clamps

  21. Chemistry Lab Drawer • Wire Gauze with Ceramic Center • Use this for heating beakers or flasks.

  22. Chemistry Lab Drawer • Erlenmeyer Flask • Used as a reaction “vessel” in lab. • Swirl

  23. Chemistry Lab Drawer • Bunsen Burner

  24. Bunsen Burner Safety • 1. Never walk away from a lit burner. • 2. Never leave the gas turned on while the burner is NOT lit. • 3. Never leave a test tube in the flame while heating. • 4. Never point a test tube at someone else while heating.

  25. Chemistry Lab Drawer • Flint Burner Lighter aka Striker

  26. Chemistry Lab Drawer • Pipets and Pipet bulb • NEVER use your mouth to pipet.

  27. Pipets • Used for transferring solutions to a reaction vessel. Transfer pipets are used when accuracy isn’t absolutely necessary. • Volumetric pipets are calibrated to deliver an exact amount. Used when that is an important factor in your experiment.

  28. Chemistry Lab Drawer • Volumetric flasks

  29. Volumetric Flasks • Used for making very accurate concentrations of solutions. • Beakers/Flasks—accurate to about 5% (50,000 ppm) • Graduated cylinder—accurate to about 1% (10,000 ppm) • Volumetric Flasks—accurate about 0.04% (400 ppm)

  30. Chemistry Lab Drawer • Stirring Rods

  31. Chemistry Lab Drawer • Buret on ring stand • Used for titrations.

  32. Chemistry Lab Drawer • Test tube brushes

  33. Chemistry Lab Drawer • Red and Blue Litmus Paper

  34. Chemistry Lab Drawer • Lab Apron (Folded)

  35. Chemistry Lab Drawer • Analytical Balances

  36. Chemistry Lab Drawer • Desiccator. Used for cooling crucibles in a “dry” environment.

  37. Chemistry Lab Drawer • Round Bottom flask

  38. Chemistry Lab Drawer • Mortar and Pestle. Used for grinding up solids or mixing solids.

  39. Chemistry Lab Drawer • Triangular file for glass cutting
