1850 T. Graham in Philos. Trans. (Royal Soc.) 140 806 The diffusate or quantity of acid diffused was determined by precipitating the liquid.
1879 J. Attfield Chem. (ed. 8) 611 The portion passing through the septum is termed the diffusate, the portion which does not pass through is termed the dialysate.
1915 Science 30 July 147/1 The diffusate thus obtained is studied by pharmacological and chemical methods.
1951 H. L. Fevold in D. M. Greenberg Amino Acids & Proteins v. 298 Continue dialysis against distilled water until [the] diffusate is colorless.
1995 W. G. Hopkins Introd. Plant Physiol. xx. 416/2 The same two inhibitors are found in diffusate collected from isolated embryos placed on a moist medium.
