    A/D noise and offset will create a small potential signal with a value very close to zero. Membrane Cell Connections The Interface 5000 can be used with membrane cells. In this type of cell, a membrane separates two electrolyte solutions. Two reference electrodes are used: one in each electrolyte. Each electrolyte also contains a counter electrode.
