• The Silver-Silver Chloride electrode has been shown to possess superior characteristics to that of non-chloride silver electrodes when recording low-level A.C. and D.C. potentials. Chloridized silver electrodes present less low-frequency "noise" than gold or silver electrodes. The Koslow Silver-Silver Chloride electrodes are constructed of pure silver and then chloridized to provide stability and low noise characteristics. The Silver/Silver Chloride potential is approximately -0.199 Volts vs. Normal Hydrogen Electrode (NHE) or -0.047 Volts vs. Saturated Calomel Reference Electrode (S.C.E.) Electrode potential is stable to plus or minus one millivolt and recovers quickly from small temperature excursions.

• The Silver Chloride Electrode has applications in electroanalysis, battery testing and maintenance, corrosion testing, and electro-analytical studies.

• The porous junction tip is made with electroporous K.T. Glass and is replaceable when damaged or contaminated.

• Excellent ion transfer and low noise

• Traceable ID tags

• Packaged with care in a handy storage carton and includes instructions with S.D.S.

The Silver/ Silver Chloride Reference Electrode Potential

• More Facts: Koslow reference electrodes use a saturated KCL solution with excess KCL crystals. These can sometimes be seen on the bottom of the electrode. The extra KCL dissolves into the electrolyte as the potassium and chloride ions diffuse through the liquid junction regularly. This additional buffer of KCL extends the time before the reference cell starts to drift due to the depletion of chloride ions in the electrolyte.

• Aging: U.V. light decomposes AgCL to give silver(0), giving the electrode a black appearance. Standard fluorescent lamps should be delicate, but don't store your references in direct sunlight. Light-protected amber glass storage bottles are recommended for storing electrodes with frit in KCL filling solution. Saturated solutions of KCL have the advantage that the concentration is reproducible even if the temperature changes (if solid salt is present) and are immune to the effects of water.

• The Electro porous K.T. Glass tip is the ionically conducting electrical pathway between the inside of the reference electrode and the bulk of your cell. The Electro-porous KT Glass frit (about 1/8" long) is attached to the glass tube by a heat-shrinkable Teflon sleeve. The Glass has a low electrical resistance (under ten kilohms for the standard filling solutions) and a modest leak rate. The electrical resistance of the reference electrode 'frit' is an essential factor in determining the stability and speed of your potentiostat in actual use. When changing K.T. Glass frits, the heat-shrink tubing should be trimmed flush with the end of the K.T. Glass frit to prevent the capturing of air bubbles.
