The increasing use of Metrohm's Unitrode and Aquatrode Plus in pH measurement shows that the fixed ground joint is being recognised as the universal diaphragm type, according to the company.
It is largely insensitive to contaminants and requires only minimal maintenance.
The fixed ground joint diaphragm is suitable for a wide range of samples, from clear, ion-deficient solutions up to highly concentrated suspensions or emulsions.
Its greatest strength is said to be its precision.
The fixed ground joint diaphragm allows low-noise potential measurements that are only dependent on the ionic strength and stirring speed to a minimal extent, thus meeting crucial requirements for a rapid and precise titration.
In order to utilise the advantages of the fixed ground joint diaphragm to the full extent in titrations, a new type of membrane glass has also been developed for the Ecotrode Plus, which, in addition to a short response time, exhibits very high endurance.
The 6.0262.100 Ecotrode Plus is the result of several years of experience, ultramodern production technology and a continuous strive to optimise products.
Until 30 November, the Ecotrode Plus is offered at a discounted price of GBP99.
