LIQUID DIFFUSION COEFFICIENT
APPARATUS
MODEL: BP 09
HE Liquid Diffusion Coefficient Apparatus (Model BP: 09) has been designed to allow for the measurement
of molecular diffusivities so that students will be able to understand the basic notions of mass transfer theory.
This liquid diffusivity apparatus relates to an equi-molal counter-diffusion process. The unit comes complete
with a diffusion cell, a transparent diffuser vessel, a stirrer system and a conductivity meter.

Measurement of mass transfer rates.
Measurement of diffusion coefficients.
The effect of concentration upon diffusion coefficient.
First order unsteady state process analysis.
Familiarisation with laboratory instruments to obtain
data for industrial process design.
DESCRIPTIONS
The diffusion cell, the most important component, has
been designed for fast diffusion rates in liquids to minimise
long observation period. The cell basically consists of a
honeycomb of accurately dimensioned capillaries,
positioned between two liquids of differing concentration
of the solute whose diffusion coefficient is to be studied.
Equipment for Engineering Education & Research
During the experiment, students shall place a small
volume of concentrated solution on one side of the
honeycomb. At the beginning, the other side of the
honeycomb consists of a large volume of pure solvent
(water). The solute diffuses from high concentration side
to the low side, causing the concentration within the larger
volume to increase. The mixture is continually stirred
while the increase in concentration is continuously
monitored using a conductivity meter.
