These electrodes excel in alkaline environments and high-temperature conditions, offering superior resistance to oxidation compared to standard metal options. Each disc is precision-machined to ensure an ultra-flat surface, providing uniform current density and highly reproducible results in critical experiments such as the Oxygen Evolution Reaction (OER), water electrolysis, battery testing, and electroanalytical chemistry. Whether you are performing cyclic voltammetry or long-term stability tests, our nickel electrodes deliver the consistency your data requires.<\/li>\n<li>\n<div class=\"flex w-full max-w-full flex-col gap-3 text-base! min-w-0 text-sm whitespace-normal [&amp;_a]:text-core-foreground-tertiary [&amp;_a]:leading-tight [&amp;_a]:font-semibold [&amp;_a]:underline [&amp;_strong]:font-bold [&amp;_p]:m-0 [&amp;_p]:whitespace-pre-wrap [&amp;_ol]:my-5 [&amp;_ol]:list-decimal [&amp;_ol]:pl-5 [&amp;_ul]:mt-2 [&amp;_ul]:list-disc [&amp;_ul]:pl-5 [&amp;_li]:my-3 [&amp;_li]:list-item [&amp;_li:first-child]:mt-0 [&amp;_ul&gt;li_p]:m-0 [&amp;_li&gt;ol]:mt-3 [&amp;_li&gt;ul]:mt-3 [&amp;_hr]:border-core-borders-default [&amp;_hr]:my-3 [&amp;_hr]:border-t-[1.5px] [&amp;_hr]:border-r-0 [&amp;_hr]:border-b-0 [&amp;_hr]:border-l-0 [&amp;_blockquote]:border-core-borders-default [&amp;_blockquote]:text-core-foreground-secondary [&amp;_blockquote]:border-l-4 [&amp;_blockquote]:pl-4 [&amp;_blockquote]:italic [&amp;_blockquote_p:first-of-type]:before:content-[open-quote] [&amp;_blockquote_p:last-of-type]:after:content-[close-quote] [&amp;_h1]:mt-4 [&amp;_h1]:mb-3 [&amp;_h1]:text-4xl [&amp;_h1]:leading-tight [&amp;_h1]:font-bold [&amp;_h1]:tracking-wide [&amp;_h2]:mt-4 [&amp;_h2]:mb-3 [&amp;_h2]:text-3xl [&amp;_h2]:leading-tight [&amp;_h2]:font-semibold [&amp;_h2]:tracking-wide [&amp;_h3]:mt-4 [&amp;_h3]:mb-3 [&amp;_h3]:text-2xl [&amp;_h3]:leading-tight [&amp;_h3]:font-semibold [&amp;_h3]:tracking-wide [&amp;_h4]:mt-4 [&amp;_h4]:mb-3 [&amp;_h4]:font-semibold [&amp;_h5]:mt-4 [&amp;_h5]:mb-3 [&amp;_h5]:font-semibold [&amp;_img]:my-3 [&amp;_figure&gt;*]:my-0 [&amp;_video]:my-8 [&amp;_figure]:my-8 [&amp;_:not(pre)&gt;code]:before:content-[&quot;&#96;&quot;] [&amp;_:not(pre)&gt;code]:after:content-[&quot;&#96;&quot;] [&amp;_pre_code]:before:content-none [&amp;_pre_code]:after:content-none [&amp;_a_code]:text-inherit [&amp;_h1_code]:text-inherit [&amp;_h2_code]:text-inherit [&amp;_h3_code]:text-inherit [&amp;_h4_code]:text-inherit [&amp;_blockquote_code]:text-inherit [&amp;_thead_th_code]:text-inherit [&amp;_hr+*]:mt-0 [&amp;_h2+*]:mt-0 [&amp;_h3+*]:mt-0 [&amp;_h4+*]:mt-0 [&amp;_table]:w-full [&amp;_table]:table-auto [&amp;_table]:border-separate [&amp;_table]:border-spacing-0 [&amp;_table]:text-left [&amp;_table]:block [&amp;_table]:overflow-x-auto [&amp;_thead]:bg-core-surface-secondary [&amp;_thead_th]:border-core-borders-default [&amp;_thead_th]:border [&amp;_thead_th]:p-2.5 [&amp;_thead_th]:px-4 [&amp;_thead_th]:text-sm [&amp;_thead_th:first-child]:rounded-tl-lg [&amp;_thead_th:last-child]:rounded-tr-lg [&amp;_thead_th:not(:first-child)]:border-l-0 [&amp;_tbody_td]:border-core-borders-default [&amp;_tbody_td]:border [&amp;_tbody_td]:border-t-0 [&amp;_tbody_td]:p-2.5 [&amp;_tbody_td]:px-4 [&amp;_tbody_td:not(:first-child)]:border-l-0 [&amp;_tbody_tr:last-child_td:first-child]:rounded-bl-lg [&amp;_tbody_tr:last-child_td:last-child]:rounded-br-lg *:first:mt-0 *:last:mb-0\">\n<p>We provide a comprehensive &#8220;made-to-order&#8221; service to perfectly match your specific electrochemical cell or experimental setup. Our capabilities include a wide range of diameters (from 1mm micro-discs to 100mm+ industrial plates), various thicknesses, and specialized surface finishes from mirror-polished to sandblasted. We can integrate the nickel discs into various housings like PTFE, PEEK, or stainless steel, and offer custom electrical connections or threaded mountings based on your CAD drawings.
