The setup contains all necessary accessories to determine the diffusion coefficient of vapors (liquid) in air phase. The diffusion vessel is of high quality Borosilicate Glass with a T type diffusion tube engraved in mm scale for level readings. The vessel is mounted over a Magnetic Stirrer cum hot plate of Superior quality provided with controls for vary the temperature and RPM to calculate the rate of diffusion at different temperature. The Air Flow stream is generated using mini-air pump Diffusivity of the vapors is determined by WINKELMANN method in which liquid is allowed to evaporate in a graduated vertical glass tube over the top of which a stream of air is passed.
