Introduction to Basic Laboratory Glassware and Equipment
Introduction
Chemistry as a central science involves experimentation that includes careful
observations and good laboratory techniques. Identifying the right glassware or
equipment to use in the lab and knowing how to properly use it will help ensure safe
laboratory practices.
Each glassware is designed precisely for a particular purpose. Some are used
for situations where a more accurate volume measurement is required and others can
be used only for approximate measurements. Choosing the appropriate tool for
measurement will not only save time and effort required to get a more reliable data but
also prevent damages caused by improper handling.
Objective:
To be able to identify common laboratory glassware and understand their
uses.
I.

B. Answer the following questions:
1. What does TC on a glassware mean? Give 2 examples of glassware in the
lab with a TC label.
2. Why is the zero mark located at the top in a burette?
3. Compare and contrast beakers and Erlenmeyer flasks discussing transfer of
liquids and mixing.
4. Compare and contrast graduated cylinders and graduated pipettes discussing
how they are used and how they are read. Which one is the less accurate
glassware for volumetric measurements?
