Types of beakers by purpose
· Florence Beakers
These are known as boiling beakers. They have a thick, uniform wall thickness distribution ideal for heating. The bottom part is round in shape. The narrow neck helps to hold it securely with a clamp.
· Erlenmeyer Beakers
These beakers are also called conical or titration beakers because they have a conical shape. They take their name from the German chemist Emil Erlenmeyer. These beakers have cylindrical, narrow, and vertical neck. They taper in size as they go up. They are useful when heat from the experiments needs to be retained instead of letting it evaporate. It can be ideally used for all types of liquid handling processes.
· Volumetric Beakers
These beakers are ideal for preparing solutions. They are not suitable for heating. They have a long, narrow neck and a bulbous bottom. They have markings on the outer side for precise measurement of the volume of liquid. They can be sealed or stoppered to prevent evaporation from changing the concentration of a stored solution.
· Distillation Beakers
These beakers look similar to their round bottom version. They have a long sidearm or tube which projects from their neck. They are used to separate the components of liquids based on selective boiling and condensation temperatures. They are also called fractional or fractioning beakers.
· Filtering Beakers
These beakers come in handy in the rapid filtration of liquids. They have a tapered neck, a conical body, and a sidearm for vacuum filtration. They resemble almost Erlenmeyer beakers.
