Abstract :
The importance of diffusion phenomena in glass micropipettes filled with concentrated electrolyte solutions is well known. Nonequilibrium diffusion-rate equations for electrolyte-filled glass micropipettes are given for a model of situations of current interest: diffusion into an infinite medium. The solutions of these equations give the flux of material out of a micropipette as a function of time, concentration, and geometry.
