Single-capillary Teorell oscillator--studies with nonelectrolytes

It has been demonstrated that if in a Teorell oscillator, the membrane is replaced by a single capillary, the system behaves much better and becomes easily reproducible. It has also been demonstrated that oscillatory behavior in a Teorell-type setup is not limited to electrolytes; even nonelectrolytes can show oscillations. The only requirement seems to be that the nonelectrolyte should be capable of generating an electrical double layer in the capillary. This is the first report of a Teorell oscillator with a single capillary. Also, oscillations with nonelectrolytes in a Teorell-type setup have not been reported before.
