Description Specification

Flow meter 0.1-1.5L/min oxygen with duotight 8mm x FFL

Usage: This flow control device is designed to be used with our oxygen cylinder and regulator that can be purchased separately. Pure oxygen is the best way to get your yeast off to a cracking start. Simply use this high pressure and high capacity disposable tank to boost dissolved oxygen levels in your cooled wort.

Oxygen is great for use with high gravity beers or pilsners where you are trying to build up a large population of yeast.

Features: We would recommend the use of a diffusion stone. These small diffusion stones create very fine bubbles of oxygen in your wort and help the oxygen to dissolve into solution faster. If you want a really nice option we would recommend the use of an oxygenation wand as this is a bit more ergonomic as you have a rigid stainless tube to force the stone to the bottom of the fermenter rather than it floating to the surface.

Instructions: Attach the regulator to the top of your disposable cylinder. Turn pressure up to 1-10psi. Immerse diffusion stone in wort for 1-2 minutes. Then dial the flow meter up to 1.0L/min. The time it takes to saturate will depend on volume, temperature, depth of vessel, and type of stone (0.5mm recommended).

NOTE: Wort must be cold. It is extremely difficult to get oxygen to dissolve into hot wort so it's essential to cool wort completely before starting this process.

How To:

We recommend boiling your 0.5 micron stone for a few minutes to sanitise the stone/wand. Work out with the table how long you need to inject the oxygen and have a timer on standby.
Open up the regulator to release oxygen, adjust your flow meter to 1L a minute then submerge into your fermenter and start the timer. NEVER put your stone into wort without air flow. It could clog!
If you're pushing too much air through at a high rate, the bubbles will break at the surface and not saturate/dissolve into the wort. This is why 1L is easy to measure and ensure enough saturation as possible.
If you're finding 1L/min is breaking at the surface, slowly adjust lower. If you break flow the stone could clog.
Take out your wand/stone and dump into some steriliser liquid with the flow still on.
Then take out and turn off the regulator.
We recommend giving it a quick boil after use to keep it clean and sanitary. (Remember never to touch the stone with your fingers (use gloves) as the oils in your skin can clog it.)

Frequently Asked Questions

At what flow rate should the wort be oxygenated?

A value of 1.0 L/min is optimal for most homebrewing volumes. This ensures effective dissolution without bubbles coming to the surface. For 20-25 L of chilled wort, 60-90 seconds at 1 L/min with a 0.5 micron stone typically achieves 8-10 ppm dissolved oxygen — the target range for healthy yeast activity.

Why must the wort be cold before it is oxygenated?

The solubility of oxygen drops sharply at higher temperatures. In hot wort (above 30°C), most of the gas escapes undissolved, oxygen is wasted and the yeast remains malnourished. Cool the wort to yeast addition temperature before enrichment (18-22°C for ale, 10-14°C for lager) for maximum efficiency.

Is pure oxygen dangerous for home use?

Pure oxygen is extremely flammable and supports rapid combustion. Never use near open flames, sparks or hot surfaces. Keep the cylinder upright in a cool and ventilated place. Close the regulator after each use and check all connections for leaks. Always follow the safety instructions that came with the cylinder.

Do I need a diffusion stone or can I use the flow meter alone?

Diffusion stone is strongly recommended. Without it, oxygen forms large bubbles that rise to the surface and escape undissolved. The 0.5 micron sintered stone creates a fine mist of bubbles that dissolves quickly. An oxygen rod in a stainless tube is even more practical because it holds the stone at the bottom of the container.

How to clean and maintain a diffusion stone?

Boil the stone in clean water for a few minutes before and after each use. Never touch the stone with bare fingers — skin oil clogs pores. Use clean gloves. After enrichment, rinse briefly in the sterilizer while oxygen is still flowing, then close the regulator. Store in a dry, dust-free container.
