Lab Beaker Functionality
A beaker is a usually graduated container used for stirring, mixing and heating liquids. Its form varies, but in general, contains a wide brimmed top with a ‘beak’ to aid with pouring and a flat bottom.
Lab Beaker Types
Beakers can be made of borosilicate glass, polyethylene or polypropylene plastic, or metal. They also range in their graduation sizes, chemical and heat resistance, resilience against corrosion, autoclavability, and clarity, all depending on the specifics of the lab.
There are three common types of beakers: Griffin, Berzelius, and crystallizers.
- Griffin beakers, or ‘low form’ beakers, are the most common beaker types in the lab. They are roughly 1.4 times their diameter and come with a spout at the opening top.
- Berzelius beakers, commonly known as high-form, and are typically used for titration.
- Crystallizers, also called flat beakers given their shape, are a wide low form beaker used for crystallization and hot bath heating.
