Detailed diagram of common laboratory equipment with names and functions.

It looks like you've uploaded an image of a diagram showing various laboratory apparatus with their names and uses. However, there is no specific question or task stated in the image itself. The image is simply a labeled chart of common lab equipment.

Since no explicit problem or question was provided (e.g., "Identify this tool," "What is the purpose of X?", or "Match the equipment to its use"), I’ll assume your request is to interpret and explain what this diagram shows and possibly summarize the functions of the laboratory tools listed.

4. Test Tube Rack
- Holds test tubes upright when not in use.
5. Funnel Support
- Supports funnels during filtration; often has a metal clamp.

#### 🔹 Containers & Vessels
6. Evaporating Dish
- Made of thick glass or porcelain; used to evaporate small amounts of liquid.
7. Glass Plate
- Flat piece of glass; can be used as a cover for beakers or for evaporation.
8. Watch Glass
