Chemistry Lab Apparatuses

Introduction

• Overview of the 20 most important apparatuses used in a chemistry lab.

Apparatuses

1. Weighing Balance

   • Instrument to determine the weight or mass of an object.

2. Beaker

   • Useful as a reaction container.
   • Holds liquid or solid samples.

3. Storage Bottle

   • Used to store prepared chemicals for later use.

4. Funnel

   • Channels liquid or fine-grained substances into containers with small openings.

5. Petri Dish

   • Shallow, transparent lidded dish.
   • Commonly used to study microorganisms.

6. Glass Stirrer

   • Used to mix chemicals in the lab.

7. Volumetric Flask

   • Measures the volume of a liquid precisely.
   • Used for preparing molar and normal solutions.

8. Conical Flask

   • Used for mixing and heating solutions.

9. Pipette

   • Transports a measured volume of liquid.

10. Spatula

    • Has spoon-like scoops or flat ends.
    • Transfers chemical reagents.

11. Wash Bottle

    • Squeeze bottle with a nozzle.
    • Rinses laboratory glassware and fills volumetric flasks precisely.

12. Measuring Cylinder

    • Measures the volume of liquids and chemicals.
    • More precise and accurate than flasks and beakers.

13. Buret

    • Used in quantitative chemical analysis to measure liquid volume.

14. Iron Stand

    • Holds various glasswares like burettes and separating flasks.

15. Mortar and Pestle

    • Crushes solid chemicals into smaller pieces or fine powders.

16. Test Tube

    • Holds, mixes, or heats small quantities of chemicals.
    • Used especially for qualitative experiments.

17. Separating Funnel

    • Separates components of immiscible liquid mixtures.

18. Filter Paper

    • Separates fine solid particles from liquids.

19. Thermometer

    • Measures temperature of solids, liquids, or gases.

20. Condenser

    • Condenses vapors into liquids by cooling.
    • Used in distillation, reflux, and extraction.
