Rules for inspecting and handling HXP-an and HXP-ca electrodes, and for making up the KOH electrolyte that goes into your cell. Consult the electrode operation note for assembly and operating conditions appropriate to your hardware.

First timeRead the inspection criteria, then handling and pre-assembly checks. If you are making up electrolyte for the first time, read the KOH section first.
Done this beforeCheck for damage and debris on the assembly surfaces.
On this pageCheck damage before assembly
Check damage before assembly
Check for creases, tears, catalyst delamination, contamination and changes in edge thickness. If anything is wrong, send photographs before placing the electrode in a cell.
Protect the catalyst and sealing surfaces
- Wear gloves and handle the edges. Do not rub or scratch the catalyst-bearing surface.
- Keep the electrode flat. Do not roll or fold it.
- Do not press the surface with metal tools.
- Remove offcuts and dust from the assembly area. Debris trapped in a seal causes leaks.
Making up and handling the electrolyte (KOH)
- Handle it according to the SDS and your laboratory procedures.
- Use only KOH-compatible containers, tubing and fittings.
- Label every container with its contents, concentration and date.
- If it spills, contain it, clean it up by your institution's procedure and dispose of the waste as regulations require.
- If it reaches skin or eyes, rinse with water at once and seek medical attention if needed.
- Keep an eyewash station and a safety shower close to where KOH is handled.

| Making up and handling electrolyte | Splash-proof goggles or a face shield, alkali-resistant gloves, and a chemical apron or lab coat |
Use conditions for your own hardware
Do not apply stack press or tightening conditions directly to a test cell. Confirm assembly conditions for the gasket and cell construction.
Electrodes ship cleaned and dried. No additional pre-treatment or separate activation procedure is required.
