Electrodes

Metrohm Aquatrode^® Plus
The Aquatrode Plus is specifically designed for pH measurements and acid/base titrations in ion-deficient low-conducting samples, such as natural surface waters, deionized water or weakly buffered solutions.

An innovative fixed ground sleeve and electrolyte gel for a reference system and a highly responsive glass make the Aquatrode Plus well suited for many different environments and applications.

Metrohm Unitrode^®
Designed for a wide range of applications and industries, the Unitrode handles all samples from the difficult—such as dyes, inks, resins, polymers, beverages and suspensions—to the basic “easy-to-measure” applications with outstanding performance and stability.

With temperature specifications that reach 100°C and a fixed sleeve diaphragm, the Unitrode can handle rough measuring environments.

Metrohm Solvotrode^®
The Solvotrode combination glass reference and pH electrode is specifically designed for use with nonaqueous acid/base titrations, where it was previously necessary to use three- and four-electrode systems due to electrostatic interferences. It is the ideal tool in monitoring product quality in many areas, including pharmaceutical, petroleum, plastics and edible oil/fat industries.

Metrohm Biotrode^®
The Biotrode combination reference and pH electrode brings highly accurate and quick measurements of a larger pH electrode system to the realm of small biological samples. Designed with a 3 mm diameter immersion system for volumes up to 60 µl, a platinum wire diaphragm and an “Idrolyte” electrolyte, the Biotrode now offers reliable pH measurements to biochemical and biological systems.

Metrohm Ecotrode^®
The Ecotrode is your basic application pH electrode for the Metrohm titration systems. For pH measurements and acid/base titrations, the Ecotrode offers you Metrohm quality and reliability at a very affordable price.

Metrohm Syntrode^®
The Syntrode pH electrode rises to the challenges of the synthesis lab, such as long working life, high temperatures and complex, often alkaline, media.

Available in 30 cm and 45 cm lengths, Syntrode offers a large 20 ml capacity for electrolytes (translating to longer refill intervals), as well as a sleeve diaphragm for extremely reliable and precise measurements.

Metrohm Titrodes^®
Metrohm Titrodes and MicroTitrodes combine two measuring electrodes into a unique metal/glass electrode. Depending on your titration, one would work as the indicator electrode and the other as the reference. They are available in Ag/glass for precipitation titrations and Pt/glass for argentometric titrations—neither require changing pH.

iTrode & iConnect
Intelligent electrodes and digital inputs that will help monitor your system and keep it performing at its best.

Metrohm Surfactrodes
Metrohm Surfactrodes are a family of specialized electrodes designed specifically for the analysis of all types of surfactants. Since no universal electrode exists for these particular analyses, Metrohm offers five Surfactrodes to cover the entire spectrum, so you can select the one that is best suited for your particular application. Whether determining anionic, cationic or nonionic surfactants, or running your analysis in aqueous or in a two-phase medium, Metrohm Surfactrodes get the job done.
