Ag/AgCl Sintered Disk Electrode (with Hole)

These Ag/AgCl Sintered Disk Electrodes come as a disk with a hole typically used for manufacturing electrodes with a hole to inject conductive gel. Ag/AgCl sintered disk electrodes are great for measuring a variety of different biosignals such as EEG, EMG, EOG, ECG and especially also DC biopotentials like GSR/EDA. They come in two different sizes:

• 9mm outer diameter, 2mm hole diameter, 1mm height
• 12mm outer diameter, 6mm hole diameter, 1mm height

They come with a pre-attached pure silver (Ag) wire. The length of the silver wire is 10mm. Packaging size is one Ag/AgCl sintered disk electrode per pack.

These versatile Ag/AgCl sintered disk electrodes have the consistency of soft metal and can be re-shaped by sanding, cutting, drilling and filing. Designed for use in electrochemistry, stimulation, precision bioelectric recording, electrophysiology and neurophysiological applications.

Ag/AgCl sintered electrodes can be used as both standard and reference electrodes, due to their stability and reproducible results. Bare Ag/AgCl sintered disk electrodes show the same quality as the wired version, low offset voltage, stability, no re-chloridizing necessary, reusable and resurfacable, cold sterilization. The silver wire embedded in the electrode is of pure silver and allows for the specific connection that fits the users' needs.

Silver-Silver Chloride (Ag/AgCl) Electrodes are known for their low offset voltage, low noise and stability. Reusable and non-toxic, the electrodes can be cold sterilized and used for many years with minimal care.
