    Your HYDROGENYX Flask has just arrived. Here's how to get started, check your concentration, and maintain it over time.

Startup

Welcome to HYDROGENYX.

Everything you need is in the box:

HYDROGENYX Flask — 400 ml, 4th generation Platinum-Iridium SPE/PEM cell, touch screen

Wireless Charging Base — simply place the bottle on it to start charging

USB-C Cable — for charging anywhere, without the dock

Quick Start Guide

Your 5-year warranty on the cell is active upon delivery — no registration needed, your order number is sufficient. Learn more about the warranty

Step-by-step

Four steps, five minutes.

  1. Load

    Place the Flask on its wireless charging base, or plug in the USB-C cable. The 4,500 mAh battery provides approximately 30 electrolysis cycles per charge.

  2. Rinse, fill

    Rinse the tank with clean water, then fill with 400 ml of plain water. Run a first "blank" cycle, which you do not drink, to rinse the cell.

  3. Launch the cycle

    From the touch screen: 5-minute cycle (≈ 4.5 ppm) or 10-minute cycle (up to 9 ppm, manufacturer's data). Drink within 20 to 30 minutes — hydrogen dissipates naturally.

  4. Check it out, if you'd like

    Want proof? A DPD test kit (around €20 online) is all you need: a few drops, the water changes color, and you can read the level on the color chart. Understand the measurement

Verifiable concentration via DPD test

Everyday

Use it well, for a long time.

Which water to use?

Still water, ideally filtered or low-mineral. Never sparkling water, juice, or hot drinks in the tank.

How do I maintain it?

Rinse the reservoir with clean water after use. Once a week, run a cycle with a little diluted white vinegar, then rinse twice. Do not put in the dishwasher, do not immerse the casing.

How many glasses per day?

Typical Use: 1 to 3 glasses per day — in the morning on an empty stomach, before exercise, or in the evening. Excess H₂ is simply exhaled through breathing.

How to check the concentration?

With DPD reagent – the reference colorimetric method. To measure at home:

  • Online DPD kit (~€20)
  • Filtered water, 10-minute cycle
  • A few drops: water changes color
  • Read the level on the color chart

See the detailed method

And what if the cell wears out?

If a DPD test shows that the water is no longer properly enriched, cell replacement is free for 5 years. See warranty conditions
