Phases of burst release in receptor chamber shown with corresponding solute concentrations in donor chamber. During initial burst release, a high concentration of solute is dissolved uniformly in the P407 donor chamber. During the transition phase, local depletion occurs in areas near the membrane (red). Afterwards, the flux across the membrane reaches its steady state condition.
