What is a Beaker? Everything You Need to Know About This Essential Laboratory Tool

Introduction

The beaker is one of the most iconic and widely used pieces of laboratory glassware. Recognized for its cylindrical shape, flat bottom, and pouring lip, beakers are essential in nearly every lab environment—from chemistry and biology to pharmaceuticals, food science, and industrial research.

If you’re searching online for “beaker,” you’re likely looking for a reliable source to buy laboratory beakers, learn about their types and uses, or find the best beaker brands available in Australia. At LabFriend, we offer a comprehensive range of beakers, including borosilicate glass beakers, plastic beakers, low-form beakers, and graduated beakers, all sourced from trusted manufacturers.

In this article, we’ll explore everything you need to know about beakers—what they are, how they’re used, which types are available, and where to buy high-quality lab beakers in Australia.

What is a Beaker?

A beaker is a simple cylindrical container used in laboratories to hold, mix, heat, and pour liquids. Beakers usually feature graduation marks for approximate measurement and a spout (or pouring lip) for easy transfer of contents.

Beakers are commonly made from:

• Borosilicate glass (e.g., DURAN®, Pyrex®) – heat-resistant and chemically inert

• Plastic (e.g., polypropylene or PMP) – shatterproof, ideal for non-heat applications

• Quartz or PTFE – used in specialty applications involving extreme conditions

Common Uses of Beakers in the Lab

Beakers are one of the most versatile tools in any scientific setting. Their wide mouth and straight sides make them suitable for various applications, such as:

• Mixing chemicals or solutions

• Measuring approximate liquid volumes

• Heating substances on a hot plate or Bunsen burner

• Holding samples for titration

• Collecting filtrates during filtration

• Transferring liquids between containers

💡 Tip: Although beakers come with graduation marks, they are not designed for highly accurate volume measurements. For precision, use a volumetric flask or graduated cylinder instead.

Types of Beakers

Choosing the right type of beaker depends on your lab's specific needs. LabFriend offers a wide variety of beakers to suit all applications:

1. Low Form Beaker (Griffin Beaker)

The most commonly used beaker. It has a height approximately 1.4 times its diameter.
Best for: General mixing, heating, and sample preparation.

2. Tall Form Beaker (Berzelius Beaker)

Taller and narrower than a low-form beaker.
Best for: Sedimentation studies, titration, and reduced evaporation.

3. Graduated Beaker

Features volume markings for quick, approximate measurements.
Best for: Mixing and transferring measured liquids.

4. Plastic Beaker (Polypropylene or PMP)

Chemically resistant and shatterproof.
Best for: Field use, educational labs, and non-heat-sensitive procedures.

5. Borosilicate Glass Beaker

Heat-resistant and ideal for laboratory heating applications.
Best for: Use on hot plates or over flame in chemical labs.

How to Choose the Right Beaker

When selecting a beaker, consider the following factors:

✔ Volume Capacity – Choose from 25 mL to 2,000 mL depending on your experiment
✔ Material – Use borosilicate glass for heating, plastic for routine handling
✔ Graduation Accuracy – For rough measurement only, not for volumetric precision
✔ Chemical Compatibility – Ensure your beaker material resists the solvents or acids used

Why Borosilicate Glass Beakers Are the Most Popular Choice

Borosilicate beakers are the gold standard in scientific glassware because of their:

• Thermal resistance – Can withstand temperature shocks and heating on open flame

• Chemical stability – Ideal for acids, bases, and solvents

• Durability and longevity – Less likely to crack or break than soda-lime glass

At LabFriend, our borosilicate beakers are certified for laboratory use and compatible with hot plates, magnetic stirrers, and Bunsen burners.
