Abstract: Bulk liquid membrane oscillators containing ionic surfactants may be used for modelling the oscillatory behaviour of biological membranes. It has been found that the temperature variation has a strong influence on the oscillation patterns. Not only the regularity and frequency of oscillations have been changed, but also a new type of peaks appeared in the system containing nitromethane with increasing temperature. The influence of the membrane material (organic solvent) and the aqueous phase composition (concentration of surfactant and alcohol) on oscillation characteristics has been examined. No oscillations have been observed without ethanol and surfactant in the donor aqueous phase.
