Screen-printed electrodes (SPEs) and PCB-based electrode platforms have moved electroanalysis out of glass labware and into compact, disposable, sometimes flexible formats. They power point-of-care diagnostics, biosensors, environmental monitors, classroom kits and rapid prototyping of electrochemical sensors, with working, counter and reference electrodes all printed on the same substrate, ready to use with a few microliters of sample. The catalog covers carbon SPEs (flexible and non-flexible), modified screen-printed electrodes with SWCNT or active carbon, gold screen-printed electrodes (Au SPEs), fully-custom screen-printed electrode designs, and PCB electrodes in Au/Au/Au, Au/Au/Ag, Au/Au/AgCl, Carbon/Carbon/Ag and Carbon/Carbon/Au configurations, plus disposable gold PCB electrodes in packs of ten. Compare print materials, three-electrode layouts, manufacturer and price across suppliers, then request quotes for custom screen-printed or PCB electrode runs.
