Multi-Mode Electrode pro – a proven product now even better

The Multi-Mode Electrode pro is the product of system-mechanically stable PEEK, so wear is reduced to the atic further development of the proven Multi-Mode Elec-minimum. Furthermore, the use of metal for the threads trode. A number of innovations and improvements make was deliberately avoided. Conse quently, corrosion is no this electrode even easier to use, easier to maintain, and longer an issue, even under the most extreme working increase its lifetime. Overall, the result is an even more conditions.

reliable electrode for polarography and voltammetry.

Practical accessories

New, practical details ...

The new accessories also make work easier. With the The Multi-Mode Electrode pro is smaller and more com-help of the new wrench the capillary can now be secured pact than its predecessor. One new feature is that each with a defined torque. The wrench can also be used as a Multi-Mode Electrode pro has its own individual serial screw driver to adjust the needle valve. In addition, the number. In addition, there are markings on the electrode electrode stand has been completely redesigned. No to indicate the minimum and maximum fill levels. Users matter whether the mercury is being replenished or the can see at a glance whether there is still enough «fuel» needle or capillary is being replaced, the electrode stand available for operation. The electrode’s electrical connec-provides a secure base for the new Multi-Mode Electrode tion is now by way of a contact plug.

... for even more reliability and ease of use Of course, the Multi-Mode Electrode pro still offers all The Multi-Mode Electrode pro is made up of fewer com-the established advantages of the Multi-Mode Electrode, ponents than its predecessor, so maintenance is easier. i.e. a hermetically sealed mercury reservoir, low mercury Moreover, the threads are now distinct, i.e. the needle consumption and easy adjustment. Finally, maybe the holder and the capillary fit only into their respective posi-best feature is that the Multi-Mode Electrode pro can be tions. All the plastic screws are made of chemically and used with any of Metrohm’s current VA instruments!
