Electrolysis Accessories for R&D

Essential Components for a Complete Electrolysis System

A successful electrolysis experiment relies on more than just the cell itself. A complete and well-integrated system needs a range of electrolysis accessories designed to handle fluid management, gas separation, inline measurement, and secure cell assembly. Our portfolio is developed around the practical needs of electrochemical researchers — so you have the reliable tools required to build and operate your experimental setup with confidence.

Our Electrolysis Accessory Range

Our accessories are grouped into four functional categories, each designed to integrate seamlessly with our X-Cell and X-Stack electrolysis platforms — and with flow cells from any manufacturer that uses standard fittings.

Gas and fluid handling

• Gas-liquid separators — for safe hydrogen and oxygen handling in water electrolysis
• Multiport electrolyte reservoirs (250 mL, 500 mL, 1000 mL) — with sealed, inert-gas-compatible operation
• Hydraulic connection packs with 1/8″ or 1/4″ Swagelok-compatible fittings and PTFE tubing

Cell assembly and mechanical components

• Cell assembly stand — for uniform compression and safer handling
• Assembly package — for repeatable, leak-free builds
• Current collectors — available in Ni, Ti, 316L stainless steel, Cu, Pt-coated Ti, Au-coated, and Ti; flat and flow-field geometries

Measurement and control

• Reference electrode insert chamber — inline reference electrode housings/extra compartment
• Flow-through electrode holder — for inline measurements of cell voltage and electrolyte properties
• OCV-Cell — flow-through cell for open-circuit voltage monitoring in redox flow battery and electrolysis research
• UV/VIS Fiber-Optical Flow Cell — inline spectroscopic monitoring of electrolyte composition and redox state
• Inline pressure unit — for monitoring hydraulic resistance

Why Choose Redox-Flow Electrolysis Accessories

• Research-grade materials — materials across the range include PEEK, PTFE, PP, borosilicate glass, 316L stainless steel, titanium, and Viton/EPDM seals — matched to the chemistry of each accessory
• Standard fittings — Swagelok 1/8″ and 1/4″, GL-threaded glass ports for easy integration into existing lab setups
• Chemistry-agnostic — inert wetted surfaces compatible with aqueous, non-aqueous, alkaline, acidic, and organic electrolytes
• Bundled packages available — pre-configured sets remove guesswork when scoping a new experiment
• Third-party compatible — many of our accessories use standard fittings and integrate with third-party cells
• Custom integration support — we scope non-standard configurations on request

FAQ

What accessories do I need for a basic electrolysis setup?

At minimum: a flow cell, an electrolyte reservoir, a pump, hydraulic tubing and fittings, and – for water electrolysis – a gas-liquid separator. Temperature control and inline measurement tools are added as your research becomes more demanding. See our detailed guide for building a full electrolyser R&D setup.

Are these accessories compatible with cells from other manufacturers?

Yes. Our accessories use standard fittings (Swagelok 1/8″ or 1/4″), GL-threaded glass ports, and inert wetted materials, which makes integration into existing lab equipment straightforward. Our temperature control units in particular are designed as chemistry-agnostic inline heat exchangers that work with any electrochemical flow loop.

Can I get a bundled package for a full R&D setup?

Yes – we offer pre-configured bundles that combine reservoirs, tubing, fittings, and optional pump integrations. If you’re unsure what to order, send us a description of your experiment and we’ll scope a complete setup.

What’s the difference between 1/8″ and 1/4″ hydraulic connection packs?

The choice comes down to flow rate and system scale. 1/8″ fittings are standard for M-Cell and small X-Cell setups where volumes and flow rates are modest. 1/4″ fittings are for larger X-Cell configurations or X-Stack systems where higher flow rates and lower pressure drop matter.

Which electrolyte reservoir size should I choose?

250 mL for catalyst screening and short-duration experiments, 500 mL for standard single-cell research, and 1000 mL for long-duration stability testing or multi-cell flow loops. All three sizes share the same multiport GL-threaded architecture for reference electrodes, gas sparging, and sensor integration.

Do you sell membranes, gaskets, and electrodes separately?

Yes. These consumables are covered in our dedicated categories — a wide range of electrodes, AEM/PEM/Nafion membranes, and PTFE/EPDM/VITON gaskets sized for every cell in our platform.
