Silver/silver chloride (Ag/AgCl) EEG cup electrodes
Reusable silver/silver chloride EEG cup electrodes with highly flexible cable for EEG and PSG
The CNSAC silver/silver chloride (Ag/AgCl) cup electrode with a 250 cm cable is a reusable cup electrode for precise signal recording in EEG and polysomnography (PSG) – designed for applications with a large range of motion.
The silver-plated and chlorinated sensor enables stable signal quality with low skin-electrode impedance. The highly flexible, biocompatible TPU cable with Kevlar core offers high tensile strength, durability, and particularly low-noise signal performance.
With a cable length of 250 cm, this version is particularly suitable for long-term EEG, video EEG monitoring, and sleep laboratory applications where greater distances between the patient and the amplifier are required.
The touch-protected 1.5 mm DIN plug (DIN 42802) ensures a secure and standard-compliant connection to common EEG and PSG systems.

Recommended use:
To optimize signal quality, the skin should be prepared with an abrasive skin preparation gel. The electrode is then filled with a suitable EEG adhesive paste and secured in place.
Ideal for routine EEG, long-term EEG, video EEG, and sleep diagnostics.
Technical data sheet for "CNSAC silver/silver chloride cup electrodes"
Preparation of the skin and application of the silver-silver chloride (Ag/AgCl) cup electrodes
For a reliable measurement, first treat the patient's skin with an abrasive skin preparation gel such as Nuprep (article no.: CR-001) or OneStep® AbrasivPlus (article no.: CR-005). This process reduces the electrical resistance of the skin and thus ensures good signal quality.
Next, fill the Ag/AgCl cup electrode with an adhesive conductive paste such as lic2® electrode cream, 10 tubes x 100g or Ten20 (item no.: CR-008) and press the electrode firmly onto the prepared area. For better adhesion, a small amount of lic2® can be applied to a compress and placed over the electrode. If the electrode is placed on the face or forehead, it can also be fixed in place using Fixomull® stretch (article no.: DI-048).
