BioMed Products, in business since 1999,  is a manufacturer of reusable “Sintered Silver-Silver Chloride Electrodes” (Ag/AgCl matrix) supplying EEG Cap Manufacturers, Researchers, OEM’s, Therapist’s and Distributor’s throughout the World with quality Sensors. We work closely with our clients to design custom electrodes that fit their needs and requirements.

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

BioMed Products, Inc is known for their EEG Electrode/Sensor superiority, our electrodes are used in EEG, ECG, EMG, ENG, EOG GSR and Evoked Potentials applications.

Ag-AgCl Electrodes  

Precision Measurement of Bioelectric Signals. These electrodes have superior qualities in: baseline stability, freedom from artifact, corrosion and moisture resistance

Ag-AgCl electrodes are recognized all over the world for their low polarization, low DC offset, low drift and low noise. Ag-AgCl is virtually non-toxic because very few free silver ions can exist to cause tissue damage. A stable, low noise reference electrode.

Ag-AgCl electrodes manufactured by Biomed Products since 1999 have superior properties because they are made with high purity chemicals. A careful proprietary process results in a fine grain, homogenous mixture of silver and silver chloride. The connection to the Ag-AgCl element is made by imbedding a high purity silver wire in the matrix. The electrodes are then compressed into a 1mm thick sensor and “sintered” (heat treated) for strength and stability. A sintering process strengthens and stabilizes the entire electrode assembly. Standard lead wires are PVC insulated multi-strand copper with internal Tinsel for additional strength.  The result is a quality reusable electrode for bioelectric measurements of unsurpassed performance. Performance is significantly superior to gold and silver. They are easily reshaped by drilling, cutting or sanding.

The BioMed electrode is 1mm thick and encapsulated in durable epoxy housings. Our electrodes come with 1m or 1.5m PVC insulated lead wires, terminated with a 1.5 DIN safety socket.
We supply EEG Cap Manufacturers, Researchers, OEM’s, Therapist’s and Distributor’s throughout the World.

Why Sinter

Sintering an Ag/AgCl electrode increases its effective kinetics, which allows it to supply large currents with minimal polarization.  Sintering also causes the AgCl to adhere better to the wire.

Electrical Specifications:

Following are typical values of key parameters between pairs of electrodes of the same size measured after prolonged soaking in 0.9% saline.  

DC offset Voltage (biaspotential): 180 µV, Drift: 25 µV / h (at constant temperature) Noise: 1 µV P – P (0.1 – 1 (0.l – l kHz with 60 Hz filtered out) Polarization (counter EMF): 2 – 4µV at 0.1 µA

Sintered, Essentially non-polarizable

Resuable-Resurfacable, Reversable

Never need chloriding

Biomed Products is a leading manufacturer of high quality, re-usable, “sintered” Silver-Silver Chloride EEG, ENG, EMG, GSR, EOG, and Evoked Potentials Sensors/Electrodes.

Since 1999 BioMed Products has specialized in custom products designed to fit your individual needs providing Researchers, Distributors, and OEM’s custom “sintered” Ag-AgCl Electrodes. Our electrodes are compressed with a Silver-Silver Chloride matrix which never needs re-chloriding. At BioMed Products we manufacture our electrodes utilizing only the purest chemicals. Due to our proprietary methods and rigid quality control, we are able to adhere to the tightest tolerance in the industry.

Unlike plated or chlorided silver, the BioMed Ag/AgCl electrodes are homogeneous and solid throughout. Should the surface become damaged or contaminated, a new surface can be exposed to restore the electrode’s original performance.
