One idea is to decant into small glass bottles, and any air space replaced by an inert gas (available to some photo dealers online. I think it is called Protectan, or something like that.

Some people use a squirt of butane, from a blowlamp or Gaz light. All that matters is to displace the oxygen and the butane doesn't react with the developer. Of course, the habit of lighting up as soon as one steps out of the darkroom should be discouraged...  |
Not heard of that one, but I like the idea 
...though not of exploding afterwards  |

I wonder, which is the more expensive hobby - photo or wine? I think they sell the inert gas stuff for oenophiles...

A more ecological method (and waaaaay less dangerous) is to use marbles to fill the gap in the bottle. |

Superb idea, I remember hearing about that years ago, but never tried it. |

This is my own modified version of it:
Filtered water at room temperature. Use a similar quantity of water that you used chemicals. Pour into the tank.
1st fill, 1 inversion, empty
2nd fill, 5 inversions, empty
3rd fill, 10 inversions, empty
4th fill, 20 inversions, empty
5th fill, let it sit for 1 minute then 20 inversions, empty
6th fill, with filtered or distilled water plus a little Kodak Photoflow or other wetting agent. Agitate for a minute or two, then empty.
Hang to dry as normal.
With a typical Paterson tank you can achieve all of that with about 2.5 to 3 litres of water. |
