A beaker is a basic lab container used mainly to hold , mix, and heat liquids (and sometimes solids) during experiments.

What a beaker does (in simple terms)

  • Holds liquid or solid samples during an experiment.
  • Lets you mix chemicals with a stirrer or by swirling, thanks to its wide opening.
  • Allows gentle heating of solutions if it is made from heat‑resistant glass like borosilicate.
  • Acts as a reaction container for simple chemical reactions where you want to watch what happens (color changes, precipitates, bubbles).
  • Collects liquids from filtration or titration, basically catching or temporarily storing liquids during procedures.
  • Helps with rough volume estimates using the graduations on the side, though it is not as accurate as a measuring cylinder or volumetric flask.

Quick story-style example

Imagine you are doing a small chemistry experiment in class.

You pour some water into a beaker, add a spoon of salt, stir until it dissolves, then gently heat the beaker on a hot plate to speed things up.

Later, you pour that solution through filter paper into another beaker to catch the clear liquid.

In all of those steps, the beaker is just your reliable, simple container that makes holding, mixing, heating, and pouring easy and visible.
