H-type Sealed Microvolume Electrochemical Cell /Three-Electrode System

H-type Sealed Microvolume Electrochemical Cell /Three-Electrode System

Product Description
Shipping & Delivery
Product Overview
The FrankLab H-Type Sealed Microvolume Electrochemical Cell (5 mL / 5 mL, Three-Electrode System) is a precision-engineered dual-chamber reactor designed for high-accuracy electrochemical measurements under fully separated anodic and cathodic environments.
Compared with conventional two-electrode H-cells, this configuration introduces an independent reference electrode, enabling precise potential control—essential for mechanistic studies, kinetics analysis, and high-level academic research.
With ultra-low electrolyte consumption, interchangeable ion-exchange membranes, and gas-tight sealing, this micro H-cell is ideal for CO₂RR, ORR, HER/OER, redox mediator studies, and membrane performance evaluation.

Cell Configuration
Three-Electrode, Dual-Chamber Architecture
Each chamber (5 mL):
•Working electrode (WE) – typically in cathodic chamber
•Counter electrode (CE) – isolated in opposite chamber
•Reference electrode (RE) – independent port, positioned close to WE
Central junction:
•Interchangeable ion-exchange membrane (PEM / AEM / BPM)
•Stainless-steel clamp ensures uniform pressure and leak-free sealing
This structure eliminates product crossover while maintaining electrochemical accuracy comparable to single-cell three-electrode systems.

Key Features
•True Three-Electrode Precision
Independent reference electrode allows accurate potential control, essential for CV, LSV, CA, CP, and EIS measurements.
• Ultra-Low Volume, High Sensitivity
5 mL chambers significantly reduce electrolyte and catalyst consumption, improving signal-to-noise ratio and enabling experiments with scarce materials.
• Complete Anode–Cathode Separation
H-type geometry + membrane interface prevents:
•Product crossover
•Redox interference
•Gas mixing
Perfect for Faradaic efficiency and selectivity studies.
• Gas-Tight & Chemically Inert
All wetted components are glass, PTFE, or inert elastomers, compatible with acidic, alkaline, and organic electrolytes.

Typical Applications
•CO₂ Reduction Reaction (CO₂RR)
•Oxygen Reduction Reaction (ORR)
•HER / OER with strict compartment separation
•Redox mediator & shuttle studies
•Membrane screening and crossover analysis
•Mechanistic electrochemistry under sealed conditions

What’s Included (Standard Configuration)
•2 × 5 mL glass chambers (left & right)
•2 × PTFE sealing caps
•1 × stainless-steel membrane clamp
•O-rings & sealing gaskets
•Membrane holder (membrane not included)
Electrodes shown in images are for demonstration only and are sold separately.

Customization Options
Available upon request:
•Alternative chamber volumes (10–100 mL per side)
•Custom port diameter / thread type
•Additional gas inlet or outlet
•Quartz glass version (photoelectrochemistry)
•PEEK / PTFE electrode holders
•Two-electrode variant (simplified H-cell)
