The electroactive core is completely surrounded by glass. Therefore, the electrodes can be used in strong acids and aggressive organic solvents. Available diameters and RG values are:
Electroactive Diameter - RG Value
<<0.5 µm - ∼25
0,5 - 1 µm - ∼25
1,5 - 2,5 µm - ∼25
5 µm - ∼3-5
10 µm - ∼3
25 µm - < 3
The RG value is the ratio of the total tip radius over the radius of the electroactive disk. Length approximately 8 cm. The electrode can be connected to a preamplifier with a HEKA Microelectrode Holder (d=2.0 mm).
