Answers
TITRATION ELECTRODES
The Van London Co. (aka Van London pHoenix Co.) Titrate electrodes are specially designed for all existing Brinkmann, Metrohm and Schott titration systems. The electrode body is constructed with a glass ground joint that will fit their titration vessels. Ionics and Tytronics titrators can be fitted with this same electrode without the ground joint. Either design can be ordered depending on the titration unit.
The Titrate series have a unique annular, ceramic reference junction providing a very fast, stable response without the clogging problems that occur with a conventional reference junction. A variety of styles are offered including different reference solutions and reference chambers. Titrate models feature a refillable outer reference reservoir that can be filled with any electrolyte compatible with the sample, including those fills recommended for nonaqueous measurements. The double junction reference is recommended for samples containing organic compounds, proteins, heavy metals or compounds that interact with silver (e.g. sulfide, bromide, iodide). All Titrate electrodes are available with a detachable lead or with a cable/connector attached.
