Let's identify each piece of laboratory equipment shown in the worksheet and write down their main functions. Here is a breakdown for each numbered item:
---
1. Beaker
-
Name: Beaker
-
Function: Used to hold, mix, heat, or store liquids. It has a flat bottom and a spout for pouring.
---
2. Triple Beam Balance
-
Name: Triple Beam Balance
-
Function: Measures the mass of substances accurately (usually in grams). Commonly used in laboratories for weighing solids.
---
3. Test Tube
-
Name: Test Tube
-
Function: A small cylindrical glass container used to hold, mix, or heat small quantities of liquid or solid chemicals.
---
4. Round Bottom Flask
-
Name: Round Bottom Flask
-
Function: Used for distillation, reflux, and heating liquids. Its round shape allows even heat distribution and prevents breakage.
---
5. Dropper / Pipette (with bulb)
-
Name: Dropper (or Pipette with Bulb)
-
Function: Transfers small amounts of liquid (e.g., drops) into containers or reactions.
---
6. Graduated Cylinder
-
Name: Graduated Cylinder
-
Function: Measures the volume of liquids accurately with marked graduations.
---
7. Tongs
-
Name: Tongs
-
Function: Used to handle hot objects safely (like test tubes or beakers) without touching them directly.
---
8. Spatula
-
Name: Spatula
-
Function: Used to transfer solid chemicals from containers to other surfaces or apparatuses.
---
9. Syringe
-
Name: Syringe
-
Function: Delivers precise volumes of liquid; often used in titrations or injections in biological labs.
---
10. Burette
-
Name: Burette
-
Function: Delivers variable volumes of liquid (especially in titrations) with high precision. Has a stopcock to control flow.
---
11. Ring Stand
-
Name: Ring Stand
-
Function: Supports various lab apparatus like clamps, rings, or funnels during experiments.
---
12. Reagent Bottle (or Storage Bottle)
-
Name: Reagent Bottle
-
Function: Stores chemical solutions or reagents safely with a tight lid to prevent contamination or evaporation.
---
13. Glass Curved Tube (Condenser)
-
Name: Condenser (Liebig Condenser)
-
Function: Cools vapor back into liquid during distillation processes.
---
14. Three-Holed Stopper
-
Name: Three-Holed Stopper
-
Function: Seals a flask while allowing multiple pieces of glassware (e.g., tubing, thermometers) to pass through.
---
15. Bunsen Burner
-
Name: Bunsen Burner
-
Function: Produces a flame for heating, sterilizing, or burning substances in the lab. Adjustable flame height and temperature.
---
16. Microscope
-
Name: Microscope
-
Function: Magnifies tiny objects or samples (like cells or microorganisms) so they can be observed in detail.
