Reference Electrodes

Selecting the ideal reference electrode chemistry and form factor for a given electrochemical system can be an important decision. Princeton Applied Research and Solartron Analytical offer a variety of options ranging from the popular Saturated Calomel Reference Electrode, or SCE, for aqueous systems to a Ag/AgNO3 reference electrode for use in organic solvents. A full list of available options is provided below.

	K0077 Saturated Calomel Reference Electrode Compatible with RDE0018 Analytical Cell Kit & K0047 Corrosion Cell Kit 3.5" long 14/20 Standard Taper Joint 4 mm Porous Glassfrit on the end Saturated Potassium Chloride filling solution

	G0093 Mercury-Mercurous Sulfate Reference Electrode This reference electrode is identical in physical configuration to the K0077 reference electrode except that the G0093 contains a mercury-mercurous sulfate inner element immersed in a saturated potassium sulfate solution. The electrode is employed in situations in which the use of the saturated calomel electrode would be unsatisfactory, for example, chloride analysis, silver analysis, etc. Compatible with RDE0018 Analytical Cell Kit & K0047 Corrosion Cell Kit 3.5" long 14/20 Standard Taper Joint 4 mm Porous Glassfrit on the end Saturated Potassium Chloride filling solution

	219811 Mercury-Mercury Oxide Reference Electrode For use with the K0264 Micro-Cell Kit. All plastic (PTFE/PP) configuration consisting of 4.24M potassium hydroxide solution. This electrode is ideal for alkali or fluoride media and is suitable for battery, energy, and electrochemical applications. Compatible with K0235 Flat Cell Kit 5.5" long 7mm Porous Glass frit on the end 20% Potassium Hydroxide filling solution

	K0103 Non-Aqueous Reference Electrode Incorporates a 14/20 standard taper joint for use with the K0065 reference electrode bridge tube. Inner element (not shown) is a silver wire immersed in Acetonitrile containing 0.1 M AgNO3. This electrode is employed in applications involving non-aqueous supporting electrolytes such as Benzene-Methanol, Acetonitrile and DMF. Compatible with RDE0018 Analytical Cell Kit & K0047 Corrosion Cell Kit 14/20 Standard Taper Joint 4mm Porous Glass frit on the end

Ag/AgCl Reference Electrode (RDE0020, RDE0024, & RDE0022) Consists of 3 individual parts that must be ordered separately to form a complete reference electrode assembly.

	RDE0020 Reference Electrode Tube Assembly Compatible with RDE0018 Analytical Cell Kit & K0047 Corrosion Cell Kit 14/20 Standard Taper Joint 4 mm Porous Glass frit on the end
	RDE0024 Reference Electrode Cap Ag/AgCl Reference Wire Integrated cable for connection to potentiostat cell cable
	RDE0022 AgCl-KCl Filling Solution Saturated in both AgCl and KCl 125 mL

	K0265 Ag/AgCl Reference Electrode Compatible with K0235 Flat Cell Kit & K0264 Micro-Cell Kit 3 M NaCl/Saturated AgCl filling solution (sold Separately - part number SL0070) 4 mm Porous Glass frit on the end 9 cm long (glass body)

	G0300 Porous Glass Frits (Replaces G0100 Vycor Frits) Package of 5 4 mm diameter Includes 5 pieces of Teflon heat shrink tubing for mounting of frits

	G0194 Polyethylene Frits For use in highly alkaline solutions, pH>10, where Porous Glass frits will dissolve Package of 5 4mm diameter Includes 5 pieces of Teflon heat shrink tubing for mounting of frits
