Three-Electrode Electrochemical Cell

Controlled three-electrode testing in a compact PFA architecture

Designed for advanced electrochemical research, this three-electrode cell combines an original Swagelok PFA body with three independently accessible metallic contacts, adjustable mechanical compression and direct potentiostat connection.

Its three-contact architecture supports working, counter and reference connections while retaining a compact, fully disassemblable construction for convenient installation, cleaning and repeated laboratory use.

Product Highlights

Engineered for controlled three-electrode measurements

A modular PFA platform providing independent electrode access, chemical resistance and straightforward assembly.

01

Swagelok PFA Body

Original Swagelok PFA body and compression sealing components.

02

Three Three independent Contacts

Three independent working, counter and reference connections for potentiostatic measurements.

03

Configurable Contacts

316 stainless steel, aluminum or titanium contact options.

04

Direct Potentiostat Access

Three independently accessible 2 mm connection points.

01
Cell Body

Original Swagelok PFA construction

The cell is built around an original Swagelok PFA body with three sealed electrode ports and Swagelok compression components. PFA offers excellent chemical inertness for demanding electrochemical environments.

The body can be fully disassembled, allowing convenient installation of the electrochemical stack, access to the third electrode port, cleaning and replacement of internal components.

✓High chemical resistance
✓Low-contamination design
✓Fully disassemblable
✓Swagelok sealing components
02
Electrode Contacts

Three independently accessible electrode contacts

The cell provides three independent metallic contacts corresponding to the working, counter and reference connections. The two opposed plungers also transmit the mechanical load generated by the internal compression assembly.

316 Stainless Steel
Durable and versatile standard configuration.
Aluminum
Lightweight and cost-effective contact material.
Titanium
For more chemically demanding environments.
03
Internal Compression

Spring-loaded compression and stack adjustment

The internal spring applies mechanical preload to the main electrochemical stack and helps maintain contact between the opposed electrodes, separator and metallic contact surfaces.

Removable spacers allow the main compression assembly to be adjusted according to the thickness of the selected electrode stack.

Modular internal architecture
The spring and spacer arrangement can be adapted to different experimental configurations.
04
Sealing System

Swagelok compression ferrule sealing

The three electrode ports use Swagelok PFA compression nuts and ferrule assemblies. Tightening each nut compresses its ferrule around the corresponding metallic contact to create a secure mechanical seal.

2
Compress the ferrule
Tighten each nut to compress the corresponding PFA ferrule.
3
Secure the assembly
All three sealed ports remain accessible for adjustment and disassembly.
05
Electrical Connection

Three independent connections to the potentiostat

Each metallic contact includes a transverse 2 mm opening, allowing separate connection of the working, counter and reference channels to compatible potentiostat leads.
