Beakers are among the most commonly used pieces of laboratory equipment. They are found in schools, universities, research laboratories, pharmaceutical facilities, healthcare laboratories, and industrial testing environments.
Understanding the different types of beakers and their uses is important because not every beaker is designed for exactly the same purpose. Beakers can vary in shape, material, capacity, heat resistance, and application.
ZyphorLabs supplies laboratory glassware and other laboratory products for research, education, healthcare, pharmaceutical, and industrial applications across South Africa.
What Is a Laboratory Beaker?
A laboratory beaker is a cylindrical container used for holding, mixing, heating, and transferring liquids and other suitable substances.
Most laboratory beakers have:
- A flat bottom
- Straight or slightly angled sides
- An open top
- A pouring spout
- Volume markings
Beakers are available in different capacities, ranging from small laboratory containers to larger vessels for handling greater volumes.
Although many beakers have graduation markings, they are generally used for approximate volume measurements rather than highly precise analytical measurements.
What Are Beakers Used For?
Beakers have many uses in laboratory environments.
Common uses include:
- Holding liquids
- Mixing chemicals
- Preparing solutions
- Heating suitable substances
- Transferring liquids
- Collecting samples
- Conducting experiments
- Performing general laboratory procedures
The exact use depends on the type of beaker and the laboratory procedure.
Main Types of Beakers
There are several common types of laboratory beakers.
The most widely recognized types include:

The correct plastic material should always be selected according to chemical compatibility and temperature requirements.
Low-Form vs Tall-Form Beakers
One of the most common comparisons between types of beakers and their uses is low-form versus tall-form designs.
| Feature | Low-Form Beaker | Tall-Form Beaker |
|---|---|---|
| Shape | Short and wide | Tall and narrow |
| Common Name | Griffin beaker | Berzelius beaker |
| Stability | Wide base | Narrower profile |
| Mixing | Convenient for stirring | Suitable for general procedures |
| Laboratory Space | Uses more bench width | More space-efficient |
Both designs can be useful depending on the laboratory procedure.
Common Beaker Sizes
Beakers are available in many different capacities.
Common sizes include:
- 50 ml
- 100 ml
- 150 ml
- 250 ml
- 400 ml
- 500 ml
- 600 ml
- 1000 ml
- 2000 ml
The correct size depends on the amount of material being handled.
Laboratories should avoid using unnecessarily small containers because liquids may spill during mixing or heating.
How to Choose the Right Beaker
When choosing a laboratory beaker, consider several factors.
1. Capacity
Choose a capacity suitable for the amount of liquid or material being handled.
It is generally useful to leave sufficient space inside the beaker when mixing liquids.
2. Material
Beakers can be manufactured from glass or different plastic materials.
The material should be selected according to:
- Chemical compatibility
- Temperature requirements
- Breakage risk
- Intended procedure
3. Shape
Choose between low-form, tall-form, or other designs depending on the laboratory procedure.
4. Heating Requirements
If the beaker will be heated, ensure that the specific product is designed and suitable for the intended temperature and heating method.
5. Measurement Requirements
Beaker graduations are generally intended for approximate measurements.
For precise volume measurement, laboratories may need equipment such as:
- Volumetric flasks
- Measuring cylinders
- Pipettes
