Platinum electrode tip in a glass shaft, for CVS applications



Highlights

• Outstanding chemical resistance through the exclusive use of glass and platinum

• Operation also used in aggressive acids, bases, oxidants or solvents

• Long lifetime

• High stability and reproducibility of the measurements

• Rapid conditioning

• Ideal for GLP-compliant work due to serial numbers and individual quality certifi cates

• Very low background current

• Can be combined with all existing RDE drives with M3 threads

• Fits all Metrohm VA stands Robust and long-lived The new platinum electrode tip with glass shaft was espe-The platinum wire is embedded in glass.
