Corrosion Test Electrochemical cell
Modular corrosion test cells for flat specimens and coated panels, available in jacketed or unjacketed designs with multi-port tops for electrodes, gas handling, and accessories.
Corrosion Test Electrochemical Cells for Research
Introduction
Corrosion cells are purpose-built electrochemical vessels that hold your electrolyte and test specimen while accommodating reference, counter, and auxiliary hardware for techniques such as DC polarisation, EIS, electrochemical noise, and galvanic corrosion. Configurations range from compact coating-evaluation fixtures to jacketed flat-coupon cells that enable precise temperature control and gas management.
Key Features & Specifications
- Cell formats: flat coupon cells, five-port/multi-port general-purpose cells, and localised coating-evaluation cells.
- Materials: borosilicate/Pyrex glass bodies, PTFE or polymer end-caps and seals; optional PEEK/polycarbonate elements depending on kit.
- Jacketed options for circulating thermostatic fluid and stable temperature control during EIS or kinetic studies.
- Porting: typically 5–7 ports for WE holder, reference electrode (e.g., SCE/Ag/AgCl), one or two counter electrodes (graphite/Pt), gas inlet/outlet, salt bridge/thermowell.
- Volumes and working area: from small (≈5–50 mL) for coating evaluation to 250–1000 mL for general corrosion testing; flat-coupon holders standard.
- Typical temperature and media limits are subject to material choice (HF commonly excluded).
- Compatible with most potentiostats/galvanostats and accessories for EIS, RDE/RRDE add-ons (where supported by kit family).
Applications
- Coating/paint evaluation on metal sheets and panels (localized isolation of test area).
- General corrosion studies: Tafel/LSV polarization, EIS, electrochemical noise, galvanic corrosion, crevice pitting assessments.
- Temperature-dependent corrosion kinetics and inhibitor screening with jacketed cells.
Material Options
- Glass body: borosilicate/Pyrex for chemical resistance and visibility.
- Wet-end components: PTFE caps, O-rings, and seals; optional PEEK/polymer end-plates in some kits.
- Electrodes: graphite or Pt counter; Ag/AgCl or SCE reference; PTFE/SS coupon holders for flat specimens.

FAQs
- When should I choose a jacketed corrosion cell?
Use jacketed cells when temperature stability influences corrosion rate or impedance spectra; circulation maintains setpoint during long EIS runs. - How many ports do I need?
Five ports cover WE, RE, CE, and gas handling; seven-port tops add room for salt bridge, thermowell, or additional CE/auxiliaries. - Can I evaluate painted or coated panels?
Yes, use a coating evaluation cell that isolates a defined area on the sheet; common test spots are in the 40–45 mm range. - Are HF electrolytes allowed?
Generally no. HF is commonly excluded due to glass compatibility limits; consult the specific kit bill of materials.
