A Complete List of Chemistry Lab Equipment and their Uses
Performing experiments in the laboratory require skills and perfection, I have composed a list of 50 chemistry lab equipment and their uses in the laboratory.
This is a guide on the list of lab pieces of equipment and their uses. This is the same as saying use of apparatus used in Chemistry.
There are different duties one could carry out in the chemistry laboratory and will certainly require specific lab equipment or apparatus. As a matter of fact, in Chemistry, we often take accurate measurements of mass, time, and temperature.
Mass is measured using Balance. A top pan balance measures in kilogram, it weighs chemicals in the laboratory to two decimal places
Temperature is usually measured using a thermometer. The thermometer reading should be taken when the thermometer is inserted into the liquid. The reading in degree should be to one-tenth of a degree accuracy.
Time is measured accurately using electronic stop clocks. They measure seconds to two decimal places.
For accurate and precise measurements, a specific apparatus may be needed. Your ability to deduce the apparatus that would give you accurate measurement is invaluable.
What is Accuracy? This is the closeness of a measurement to the actual value.
What is Precision? This is the closeness of measurements to each other.
