We offer electrode tips with a diameter of 3 mm or 5 mm for conventional Metrohm electrode holders or for the Autolab RDE rotating electrode.

A 5mm empty tip is available for custom materials.

2mm electrode tips are also available for Metrohm electrode holders (not compatible with Autolab RDE).

The following materials and sizes are available:

Platinum with a diameter of 2, 3 and 5 mm

Gold diameter 2, 3 and 5 mm

Silver with a diameter of 2, 3 and 5 mm

Glassy carbon with a diameter of 2, 3 and 5 mm

Empty tip 5 mm

Electrodes 2 mm glass housing

3/5 mm electrodes PEEK housing

Temperature range 0 - 40 ° C.

Working electrode tip holders, compatible with Metrohm vessels. The holder with the tip is connected with the appropriate M3 / M4 connector.
