Unitrode 6.0259.100 – Combined pH titration electrode for complex environments and high temperatures
The Metrohm Unitrode 6.0259.100 is a combined pH electrode specially designed to meet the analytical challenges posed by complex, viscous or highly alkaline samples. Thanks to its optimised design, this electrode stands out for its robustness, accuracy and compatibility with a wide variety of titration applications. It is perfectly suited for use in demanding environments where standard measurement conditions fail to guarantee reliable and reproducible results.
Its main advantage is its fixed ground glass junction, which offers remarkable resistance to contamination. This type of diaphragm allows for constant electrolyte exchange while limiting external interference from impurities in the samples. This feature makes it a preferred solution for laboratories dealing with complex and heterogeneous matrices. Unlike traditional electrodes, the Unitrode maintains reference potential stability even when the system is subjected to high chemical loads.
The electrode uses a 3 mol/L potassium chloride (KCl) solution as the reference electrolyte, which ensures compatibility with Ag/AgCl reference systems. However, for measurements at temperatures above 80 °C, Metrohm recommends using the Idrolyte electrolyte, which offers increased stability and better thermal resistance. The Unitrode is therefore ideal for high-temperature titrations, which are often required in the chemical, pharmaceutical and food industries.
In terms of connectivity, the electrode is equipped with a standard Metrohm connection head (type G) for easy connection to all compatible devices via cables of various lengths. Its ergonomic design and compatibility with specific accessories (including sleeves and storage containers) ensure practical use and smooth integration into automated or manual analysis chains.
Optional storage and cleaning solutions, including the pHit Kit and mild cleaning solution, significantly extend the electrode's service life and ensure optimal performance over the long term. Metrohm recommends regular maintenance, including gentle cleaning of the glass membrane and junction, to prevent premature wear while maintaining consistent analytical accuracy.
Thanks to its high-quality design and adaptability, the Unitrode 6.0259.100 is the go-to choice for professionals looking for a durable, accurate, and efficient solution for pH measurement in challenging conditions.
