{"product_id":"ehyspetpmmcp","title":"ECS-HY Portable Mini Multiple-Channel (4 \u0026 8) Potentiostat (±1.2V, ±3 mA) for Screen-Printed Electrode Testing, EHYSPETPMMCP","description":"\u003cp\u003eMini and pocket-sized potentiostats optimized for screen-printed electrodes (SPEs) prioritize direct edge-connector mating, low power consumption, and portability for point-of-care, environmental, and biosensor testing.\u003c\/p\u003e\n\u003cp\u003eThe Critical Considerations for SPE Testing: (1) \u003cstrong\u003eConnector Interface\u003c\/strong\u003e: Most commercial SPEs feature standard 2.54 mm pitch contact tabs (WE, RE, CE). Verify whether the mini potentiostat has an integrated slot (e.g., Sensit BT, ECWP100) or requires an external clamshell\/boxed cable adapter. Integrated slots eliminate cable noise but make immersion into stirred beakers awkward without an extension cable. (2) \u003cstrong\u003eCompliance Voltage \u0026amp; Dynamic Range\u003c\/strong\u003e: Miniature, USB- or coin-cell-powered potentiostats often have internal supply rails clamped to ~±2.0 V or ±3.0 V. This is well-suited for aqueous sensing (glucose, enzymatic redox mediators, ferricyanide), but insufficient for wide-window organic electrolytes or high-resistance thin-film traces requiring ≥ ±5 V compliance. (3) \u003cstrong\u003eTechnique Needs (Voltammetry vs. EIS)\u003c\/strong\u003e: \u003cem\u003eVoltammetric Sensing (DPV \/ SWV \/ Amperometry)\u003c\/em\u003e: For heavy metal stripping, pesticide detection, or enzymatic glucose assays, basic DC instruments offer high signal-to-noise at low cost. \u003cem\u003eLabel-Free Impedance Biosensors\u003c\/em\u003e: If detecting antibody-antigen binding or DNA hybridization via charge-transfer resistance (R_ct), an EIS-capable unit running up to 100–200 kHz is required. (4) \u003cstrong\u003eBatch vs. Drop-Casting Compatibility\u003c\/strong\u003e: If testing directly via drop-casting (10–50 µL on the horizontal strip), a horizontal top-loading slot works best. If using an immersion cell with a stirred vial or deoxygenation line, ensure the instrument provides standard 2 mm pinouts or a flexible ribbon cable lead to the cell lid.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 525.2px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEHYSPETPMMCP (EHY-SPET-PMMCP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 67.2px;\"\u003e\n\u003ctd style=\"height: 67.2px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 67.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC110-220V±10% (DC12V adaptor), single phase, 50\/60Hz, 50 W\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 165.2px;\"\u003e\n\u003ctd style=\"height: 165.2px;\"\u003e\n\u003cp\u003e\u003cem\u003eCritical Features\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"height: 165.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003ePotential Range: ±1.2V (Resolution: 1 mV)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCurrent Range: ±3 mA (Resolution: 330 pA)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSupport Multiple Working Electrode System: (1) Four Channels: WE0, WE1, WE2, WE3, CE, RE; (2) Eight Channels: WE0, WE1, WE2, WE3, WE4, WE5, WE6, WE7, CE, RE\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMeasuring Techniques: CV\/LSV\/i-t\/DPV\/SWV\/EIS\/OCP\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 187.6px;\"\u003e\n\u003ctd style=\"height: 187.6px;\"\u003e\n\u003cp\u003e\u003cem\u003eSoftware\/Bluetooth\/Others\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"height: 187.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eThe Testing and Analysis software is included.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBluetooth and USB port are available for data export\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e          \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/EHYSPETPMMCP_02_100x100.jpg?v=1788762253\" alt=\"\" style=\"float: none;\"\u003e         \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/EHYSPETPMMCP_03_100x100.jpg?v=1788764761\" alt=\"\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"height: 10px;\"\u003e\u003cem\u003eDimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 10px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eL50 * W50 * H18 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"height: 47.6px;\"\u003e\u003cem\u003eWeight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 47.6px;\"\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e~0.5 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S1572665723002400\"\u003eD.
