These disk inserts are designed for use with our ChangeDisk RDE and RRDE tips. One of our most popular insert materials are carbon-based. Here, we offer high purity glassy carbon and pyrolytic graphite (edge-plane and basal-plane orientations).
This bundle gets you started with a ChangeDisk Rotating Disk Electrode (RRDE) with platinum ring, an interchangeable glassy carbon disk insert, and a Pine Research Modulated Speed Rotator (MSR) – the most popular electrode rotator in the world.
8 lis 2018 · Here we show the importance of the accurate amount of catalyst (e.g., Pt) on glassy carbon (GC) disk of RDE in TF-RDE experiment by characterizing the commercial catalysts for their electrocatalysis performance (electrochemical surface area and ORR activity) values.

This disk is mounted (coaxially) on a rigid shaft and typically rotated at rates between 200 and 2500 RPM using an electrode rotator (see: Figure 2). For ORR studies, glassy carbon is used as the disk material and catalyst support because carbon is electrochemically inert over the range of electrode potentials relevant to ORR study.
30 cze 2010 · High quality catalyst films can be obtained by casting catalyst-containing inks on glassy carbon electrodes. An example of a glassy carbon electrode is a 5-mm diameter glassy carbon disk with a geometric area of 0.196 cm 2 embedded in a Teflon cylinder (Pine Instruments).
15 lis 2011 · By comparison to the results in Fig. 2, the rotational film is very uniform over the entire surface of the glassy carbon disk; no coffee ring structure is visible. The SEM micrographs clearly indicate that the film obtained is dense and covers the glassy carbon surface entirely.
