| Abstract: | Summary The effective diffusion coefficient of ethanol in a 4 %(w/v) agarose gel at 25°C was measured using a diaphragm diffusion
cell. The reproducibility was very good; a standard deviation of only 2% was obtained. The mean value (9.5×10−6 cm2/s) agreed well with available theory and previous investigations. |
