Beaker

Beaker – Laboratory Glassware

A beaker is one of the most commonly used pieces of laboratory glassware in scientific laboratories, research centers, and educational institutions. It is a cylindrical container with a flat bottom and a small spout on the rim that helps in pouring liquids easily. Beakers are mainly used for mixing, heating, and holding chemicals or liquids during experiments.

Beakers are usually made from borosilicate glass, which is resistant to heat and chemical reactions. Because of this property, they can safely be used on hot plates, Bunsen burners, or other heating equipment. Some beakers are also made from plastic materials like polypropylene for experiments where chemical resistance and durability are required.

Types of Beakers

There are several types of beakers used in laboratories depending on the application.

1. Griffin Beaker

The Griffin beaker is the most common type of beaker. It has straight sides and a wide diameter, making it suitable for general laboratory work.

2. Tall Form Beaker

Tall form beakers are narrower and taller than standard beakers. They are useful when less evaporation is required.

3. Low Form Beaker

Low form beakers are shorter and wider, which makes them ideal for heating and mixing solutions.

Features of a Beaker

Beakers are designed with certain features that make them suitable for laboratory use:

Flat bottom for stability

Graduated markings for approximate measurements

Pouring spout for easy transfer of liquids

Heat and chemical resistance
