Common Chemistry Lab Equipment

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 • Test Tube Rack and Test Tubes • Test Tubes are another “primary” reaction vessel

4. Chemistry Lab Drawer • Test Tube Holder

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

6. Chemistry Lab Drawer • Beakers

7. Chemistry Lab Drawer • Micro Spatula and Scoopula • Used for measuring small amounts of chemicals. • Never stick these directly into a bottle of chemicals. • You can contaminate the entire bottle.

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

9. 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.

10. Volumes. • We will work with liters (L) and milliliters (mL) in this class. • 1000 mL = 1L. • 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.

11. Chemistry Lab Drawer • Thermometers

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

13. Chemistry Lab Table • Tongs

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

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

16. Chemistry Lab Drawer • Watch Glass

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

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

19. Chemistry Lab Drawer • Bunsen Burner

20. 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.

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

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

23. Chemistry Lab Drawer • Volumetric flasks

24. 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)

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

26. Chemistry Lab Drawer • Stirring Rods

27. Chemistry Lab Drawer • Lab Apron (Folded)

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