It looks like you are listing different types of laboratory equipment. Here's a breakdown of each item you've mentioned:
1. **Air Displacement Pipette (A,1)**:
- A precise instrument used to transfer small volumes of liquid, typically ranging from microliters to milliliters. It uses air displacement to create a vacuum that draws liquid into a disposable tip.
2. **Positive Displacement Pipette (A,b)**:
- This type of pipette directly displaces the liquid using a plunger that compresses the liquid rather than relying on air displacement. It is suitable for viscous liquids and offers high accuracy.
3. **Test Tube (B)**:
- A cylindrical glass or plastic tube used to hold, mix, or heat small quantities of substances. Commonly used in laboratories for experiments and reactions.
4. **Graduated Measuring Cylinder (C)**:
- A tall, cylindrical container with markings to measure the volume of liquids. It is designed for accuracy and is ideal for measuring and pouring liquids.
5. **Volumetric Flask (D)**:
- A type of glass flask used for making precise volume measurements. It has a long neck and a single graduation mark for a specific volume, making it ideal for preparing standard solutions.
6. **Beakers (E)**:
- Simple cylindrical containers used for mixing, stirring, and heating liquids. They are not as precise as volumetric flasks but are versatile and widely used in lab settings.
7. **Petri Dishes (F)**:
- Shallow, flat dishes made of glass or plastic used for culturing microorganisms, growing cells, or conducting small experiments.
8. **Refrigerators (G)**:
- Equipment used to store samples, reagents, or biological materials at low temperatures to preserve their integrity.
