Item Description

Sci-tech Liquid Diffusion Coefficient Apparatus Model TH 054 is designed for measurement of molecular diffusivity & contains a diffusion cell, transparent diffuser vessel. The diffusion cell has been designed for fast diffusion rates in liquids to minimize 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.
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.
Detailed Operation & Maintenance Manual is provided along with the trainer.
