Laboratory Measuring Apparatus

Basic Information About Common Laboratory Apparatus

In scientific laboratories, different types of apparatus are used for various functions, including measuring, holding, heating, and mixing substances. Below are some of the most common laboratory containers and their functions:

 

1. Beaker

A beaker is a versatile container used for dissolving, mixing, and heating large amounts of liquids. It has a cylindrical shape with a flat bottom and a spout for easy pouring.

 

2. Test Tube

Test tubes are small cylindrical glass containers used as reaction vessels in experiments that involve small amounts of reactants. They are essential for chemical reactions and biological studies.

 

3. Flask (200 mL)

A 200 mL flask serves as a reaction vessel, a gas generator, or a container for heating liquids and solutions. Its narrow neck helps in controlling the release of gases and prevents spills.

These laboratory containers are essential for conducting experiments safely and efficiently. Understanding their uses ensures better handling and proper laboratory procedures.
