title: An osmometer for aqueous biopolymer solutions.
abstract: A sensitive osmometer for the study of the osmotic pressure of aqueous protein solutions is presented. Equilibrium is reached within 1 to 2 h and is reproducible to about 1 N.m-2 (= 0.01 cm H2O). The method allows the determination of dissociation constants of proteins down to 1 x 10(-8) M.
