BCHE 111 – CHEMISTRY FOR ENGINEERS
LABORATORY EXERCISE 1: COMMON LABORATORY APPARATUS
Author: APRIL VINCENT MONTERO
Brief Description: The common laboratory apparatus are the basic things that are applied
everywhere, in physics and chemistry, in medical laboratories and educational institutions.
Each piece has its unique name and is meant to be used in a particular way.
COMPETENCIES
This exercise will enable the students to identify the different laboratory apparatus which
will be used in future experiments. 40 common apparatus in chemical engineering laboratory
will be illustrated and its uses will be written below each figure.
LABORATORY EXERCISE 1: COMMON LABORATORY APPARATUS
1.
BEAKER
Use(s): It is used for holding liquids. It is
used for containing a chemical reaction,
measuring liquids, heating them over a
Bunsen burner's flame or collecting
them in a titration experiment.
2.
BURNER
Use(s): It is commonly used as a heat
source in laboratory experiments such
as for heating, sterilization, and
combustion.
3.
BURETTE CLAMP
Use(s): It is used specifically to hold and
secure a burette on a stand, so that a
burette is fixed and more convenient for
the experiment.
5. CORK BORER
