Liquid Diffusion Coefficient Apparatus Manufacturer and Supplier

Description:

The liquid diffusivities coefficient apparatus laboratory equipment has been designed to enable measurement of molecular diffusivities relating to an equimolar counter-diffusion process and in so doing, familiarise students with the basic notions of mass transfer theory.
It has developed a unique diffusion cell which overcomes the traditional problem of slow diffusion rates in liquids requiring long observation times but without sacrificing accuracy or introducing convective effects. Essentially, the cell consists of a honeycomb of accurately dimensioned capillaries positioned between two liquids of differing concentration of the solute, whose diffusion coefficient is to be determined.

Features:
  • Bench mounted apparatus for the determination of diffusion coefficients of components in the liquid phase. The method employs a diffusion cell of capillary tubes so constructed to permit equimolar counter diffusion between liquids of differing concentration each side of the cell without convective effects being present
  • Concentration changes on one side of the cell with respect to time are measured with the conductivity cell and the meter provided and a magnetic stirrer keeps the bulk solution well mixed
  • Possible to obtain reproducible and accurate values of diffusivity within a period of 1.5 hours of practical laboratory time
  • Battery powered
Technical Details:
  • Diffuser vessel: Capacity 1l
  • Conductivity meter: 3 ranges 199.9μ5 to 19.99mS
  • Computer output: RS232
