Beakers are standard instruments that can be found in any laboratory. They are used to mix, stir, or heat liquids in a safe glass vessel. They can come in many different shapes and sizes to sufficiently handle liquids, and they can either be disposable or reusable.

Your lab beakers are important supplies and should be treated with care. They can withstand very high temperatures and are designed to last a long time. It’s crucial to know their types, materials, and cleaning methods to ensure safety and proper handling is your top priority.

Beaker Materials

Beakers can be made of a few materials that contain thermal shock resistance technology. These materials include:

  • Glass – Borosilicate glass is the most used type of beaker. It’s highly resistant to chemical corrosion and extreme temperatures up to 400°
  • Metal – Metal beakers can be made of aluminium or stainless steel. They’re more resistant to shattering and can withstand temperatures between 340°C and 550°C
  • Plastic – Some plastic beakers are made of ethylene-chlorotrifluoroethylene which can resist chemicals quite well. Plastic beakers have lower temperature resistance, from 150°C to 260°C

Beaker Types

Griffin beakers are standard in a lab. They are “low form”, being taller than they are wide with straight sides. Many of these have spouts and handles to safely pour chemicals and other liquids. They feature flat, wide bottoms, making them essential for heating, especially on a hot plate.

Berzelius beakers are “tall form” and are twice as tall as they are wide. Their sides are slightly tapered, and also may feature a spout and handles.

The Crystallizer is the third type of beaker, which typically doesn’t have measuring markers like their two counterparts.

Finally, the Phillips beaker resembles the Crystallizer. The difference is the mouth of the Philips beaker is narrower than its base.

Cleaning Methods

Beakers should be cleaned after each use to remove contaminants. This can usually be done in hot water or a labware cleaner. Always mind the manual for the best cleaning methods for each type of beaker.

How Do You Use Your Beakers?

Do you use your beaker to watch reactions, or catch liquids from filtrates? No matter your usage, your beaker is an integral part of your laboratory. Take special care of them and be mindful of your scientific purpose!
