  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 • Scoopula • Used for measuring small amounts of chemicals. • Never stick these directly into a bottle of chemicals. • You can contaminate the entire bottle.

  4. Chemistry Lab Drawer • Lab Apron (Folded) • Goggles (top right)

  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 • Use these to accurately measure liquids in lab. Never use beakers to measure. • The answer on the SOL is always GRADUATED CYLINDER.

  8. Volumes. • We will work with liters (L) and milliliters (mL) in this class. • 1000 mL = 1L; 1000 L = 1 m3 • Cubic centimeters (cm3) and milliliters (mL) are different names for the same amount. 1 mL = 1 cm3. • 1 drop from a dropper is approximately 0.05 mL. So, 20 drops = 1 mL.

  9. Chemistry Lab Drawer • Test Tube Holder

  10. Chemistry Lab Drawer • Thermometers

  11. Chemistry Lab Drawer • Other stuff on FRONT SIDE • Stoppers (under goggles) • Hose clamp (under well plate) • Disposable pipet (right of grad cylinder) • Combustion spoon (looks like a soup ladle)

  12. Chemistry Lab Table • Tongs

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

  14. Chemistry Lab Drawer • Watch Glass

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

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

  17. Chemistry Lab Drawer • Clay Triangle • Use this when heating crucibles.

  18. Chemistry Lab Drawer • Beakers

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

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

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

  22. Chemistry Lab Drawer • Bunsen Burner

  23. 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.

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

  25. Chemistry Lab DrawerNot on Handout • Volumetric flasks

  26. 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)

  27. Chemistry Lab DrawerNot on Handout • Buret on ring stand • Used for titrations.

  28. Chemistry Lab DrawerNot on Handout • Stirring Rods

  29. Chemistry Lab DrawerNot on Handout • Mortar and Pestle. Used for grinding up solids or mixing solids.
