Here are some common laboratory apparatus used to heat, test, and store chemicals:
1. Beaker
- Uses: To hold, mix, and heat liquids. They can also be used for titration.
- Drawing: [Imagine a cylindrical glass container with a spout and measurement markings.]
2. Conical Flask (Erlenmeyer Flask)
- Uses: To mix chemicals, heat liquids, and can also be used for titration.
- Drawing: [Imagine a flask with a wide base and a narrow neck.]
3. Test Tube
- Uses: To hold small amounts of liquid or solids for testing reactions.
- Drawing: [Imagine a small cylindrical tube that is open at one end.]
4. Bunsen Burner
- Uses: To provide a single open flame for heating substances.
- Drawing: [Imagine a small metal stand with a vertical tube where gas is burned.]
5. Test Tube Rack
- Uses: To hold multiple test tubes in an upright position.
- Drawing: [Imagine a frame with holes that fit the test tubes.]
6. Volumetric Flask
- Uses: To prepare standard solutions and store liquids with precise volumes.
- Drawing: [Imagine a glass flask with a flat bottom and a long neck with a stopper.]
7. Petri Dish
- Uses: To culture microorganisms and store small volumes of liquids.
- Drawing: [Imagine a shallow, round glass or plastic dish with a lid.]
8. Reagent Bottle
- Uses: To store chemicals safely.
- Drawing: [Imagine a small glass bottle with a stopper.]
Illustrations
Unfortunately, I can't create or display images directly. However, you can easily find illustrations of these apparatuses online or in laboratory textbooks. Each of these items is common in laboratories and can typically be found in chemistry labs or educational settings.
