Pellet electrodes have a cylindrical AgCl pellet embedded on a 0.25 x 70 mm wire.
The E255 electrode (64-1317) has been discontinued and is no longer available. We recommend using a thicker silver wire (0.37 mm; 64-1320) or the popular E205 electrode listed here.
Pellet and disk electrodes are ideally suited for making custom assemblies of skin electrodes or other bioelectrical recording and stimulation apparatus.
Disc electrodes with lead wires
These Ag/AgCl disc electrodes are made with a flexible 20 cm lead wire attached to the back.
Electrodes can be used as direct-contact skin electrodes, or subcutaneously in temporary applications on research animals.
Ag wires made of annealed 99.99% pure silver are supplied for the convenience of researchers to fashion their own electrodes.
