Beakers are common laboratory glassware used for measuring, mixing, and heating liquids. They come in various sizes and shapes to accommodate different experimental needs. Here are some types of beakers:
1. Standard Beakers:
Standard beakers are the most common type of beakers. They have a cylindrical shape with a flat bottom and a spout for easy pouring. Standard beakers come in various sizes, ranging from small (e.g., 50 mL) to large (e.g., 2,000 mL or more).
2. Griffin Beakers:
Griffin beakers, also known as low form beakers, are similar to standard beakers but have a slightly shorter and wider shape. They are designed to be more stable and are often used for general laboratory purposes.
3. Tall Form Beakers:
Tall form beakers have a taller and narrower shape compared to standard beakers. They are useful when a larger volume of liquid needs to be held without the risk of splashing.
4. Graduated Beakers:
Graduated beakers have volume markings on the side, allowing for precise measurement of liquids. These beakers often have a spout for easy pouring and are commonly used in laboratories and educational settings.
5. Stainless Steel Beakers:
Stainless steel beakers are more durable and resistant to chemicals compared to glass beakers. They are often used for high-temperature applications or in environments where glass breakage is a concern.
6. Watch Glass:
Although not technically a beaker, a watch glass is a shallow, circular glass dish with a slight concave shape. It is used as a cover for beakers or as a surface for evaporation or crystallization experiments.
These are some of the common types of beakers used in laboratory settings. The choice of beaker depends on the specific requirements of the experiment, such as the volume of liquid, stability, and need for measurement markings.
