Safeer Chemistry and Process Industries Laboratory Chemistry and Process Industries Laboratory In the chemistry laboratory students learn how to make up chemical solutions, perform
lab techniques, play it safe in the lab, and perform chemistry lab experiments. There are
many important apparatus in chemistry laboratory. These apparatus are of great
importance since it allows experimentation of elements possible. It allows the students
to have hands-on learning thus it is made fun and easy. Common Equipments for
laboratory includes test tubes, Bunsen burner, beaker, burret, and so on.

1. Conductivity meter
A conductivity meter is an electrical device used to measure the amount of electrical
power that is conveyed through a liquid. It is used to determine the amount and types of
salts available in water. An electric current is passed through the water, and the output
used to gauge its conductivity
Figure 1: Conductivity meter
5 Department of Chemical Engineering U. E. T Peshawar Chemistry and Process Industries Laboratory 2. PH meter
A pH meter is an electronic device used for measuring the pH (acidity or alkalinity) of a
liquid .This measure the PH (1-14) of any given sample is measured with the help of this
unit.
Figure 2: PH meter
6 Department of Chemical Engineering U. E. T Peshawar Chemistry and Process Industries Laboratory 3. Rotary Evaporator
Rotary evaporator is used to study the evaporation process for variety of extracts by
changing various parameters like temperature e.g Separation of organic liquid by simple
distillation, to purify a given sample of water by simple distillation and to measure the
distillation rate, Purification of organic compound by steam distillation.

7 Department of Chemical Engineering U. E. T Peshawar Chemistry and Process Industries Laboratory 4. Viscometer
To equipment is used find the density and viscosity of unknown mixture.Viscometers
only measure in one flow condition. In general, either the fluid remains stationary and an
object moves through it, or the object is stationary and the fluid moves past it. The drag
caused by relative motion of the fluid and a surface is a measure of the viscosity. The
flow conditions must have a sufficiently small value of Reynolds number for there to
be laminar flow.

8 Department of Chemical Engineering U. E. T Peshawar Chemistry and Process Industries Laboratory 5. Stalagnometer
The unit is used to determine the surface tension of desired solvent and to find the
percentage composition of unknown mixture by surface tension method
Figure 5:Stalagnometer
6. Potentiometer Automatic Titration
Potentiometer Automatic Titration performs various types of titrations like Alkanity,
Acidity, Chlorides, Sulphideetc

This unit helps to maintain a temperature for various analytical experiments like
evaporation of solution for the measurement of total solid in it
Figure 7: Water Bath 10 Department of Chemical Engineering U. E. T Peshawar Chemistry and Process Industries Laboratory 8. Electric Oven
The unit is used to heat any sample from ambient to 550˚ C. The sterilization of various
glaze wares can be done in this electric oven

12 Department of Chemical Engineering U. E. T Peshawar Chemistry and Process Industries Laboratory 10. Muffle Furnace
Many experiments and procedures taken in the lab requires extreme heat
environment. For this purpose, the high temperature muffle furnace steps in as the
necessary part of laboratory equipment. The unit is used to the Moisture contents,
Volatile matter and Ash contents for various samples in the temperature range of
ambient to 1100˚C.
