14 Choosing the appropriate spacer disc
In order to achieve electrical contact between the electrode and the membrane, it is important
to fill the 2.3 mm gap between the T-Frit and the Membrane. This is achieved by the stack
comprised of the spacer disc (current collector) and the working electrode.
Choose a proper spacer disc height depending on the thickness of your electrode. Spacer
discs are available in different heights ranging from 0.9 mm to 2.3 mm in 0.1 mm steps. If in
doubt choose the next higher spacer disc. We recommend using the 2.3 mm spacer disc for all
electrodes in the thickness range 0 to 150 µm.
