Zensor TE100 SPEs
These Zensor screen printed electrodes (SPEs) feature a carbon working electrode (central circle), carbon auxiliary (outer annular crescent) and Ag/AgCl pellet reference electrode. They can be used as low cost disposable electrodes in aqueous solutions of moderate pH. Disposable SPEs can be used as an alternative to expensive glassy carbon or platinum electrodes for teaching experiments, or routinine analyses, where a clean r…

These Zensor screen printed electrodes (SPEs) feature a carbon working electrode (central circle), carbon auxiliary (outer annular crescent) and Ag/AgCl pellet reference electrode.
They can be used as low cost disposable electrodes in aqueous solutions of moderate pH. Disposable SPEs can be used as an alternative to expensive glassy carbon or platinum electrodes for teaching experiments, or routinine analyses, where a clean reproducible surface would otherwise require time consuming electrode polishing.
Relatively large tabs at the top of the SPE enable electrical contact with standard miniature alligator clips (no special cables required).
If using solutions that contain species which might react with the Ag/AgCl pellet reference (sulfide, iodide, cyanide, ammonia, etc.) then the Zensor SE100 SPE working electrode is recommended using a conventional reference and auxliary electrodes, with an intervening salt bridge in cases of serious interference.
Not suitable for use with organic solvents, or concentrated acidic or basic aqueous solutions.
