Three-Electrode Stainless Steel Electrochemical Cell

Controlled three-electrode testing in a robust stainless steel architecture

Designed for advanced electrochemical research, this three-electrode cell combines an original 316 stainless steel 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

316 Stainless Steel Body

Original 316 stainless steel 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 for working, counter and reference channels.

01
Cell Body

Original 316 stainless steel construction

The cell is built around an original 316 stainless steel 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 for sample installation, access to the third electrode port, cleaning and replacement of internal components. As the body is electrically conductive, electrical isolation must be maintained between the standard plungers and the body.

✓High mechanical durability
✓Rigid three-port architecture
✓Fully disassemblable
✓PTFE sealing components
02
Electrode Contacts

Three independently accessible electrode contacts

The cell provides three independent metallic contacts corresponding to the working, counter and reference electrodes. In the standard configuration, insulating films must be positioned between each plunger and the conductive stainless steel body.

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

PTFE compression ferrule sealing

The three electrode ports use 316 Stainless Steel compression nuts and ferrule assemblies. Tightening each nut compresses its ferrule around the corresponding metallic contact to create a secure mechanical seal.

1
Position the plunger
Position each metallic contact according to the cell configuration.
2
Compress the ferrule
Tighten each nut to compress the corresponding PTFE ferrule.
3
Secure the assembly
All three sealed ports remain accessible for adjustment and disassembly.
05
Electrical Insulation

0.05 mm Mylar insulation films

The conductive stainless steel body must be electrically isolated from standard metallic plungers. Thin Mylar films, also known as PET or polyester electrical-insulation films, are installed between the plungers and the cell body.

The required film thickness is 0.05 mm. Correct placement is necessary to prevent unintended electrical contact while preserving the compact geometry of the assembly. The Mylar films are not supplied with the standard cell.
