Vacuum sealing fixer to extend lifespan?

[AveryMiller]

Hope everyone is doing well!
I'm in the process of buying developer and fixer to develop my first B&W film (I started with C-41 first!), and I'm trying to find chemicals that are as shelf stable as possible. It's easy as for the developer, because Rodinal apparently lasts a long time, and Ilford rapid fixer has a really nice shelf life as well. From what I've seen, as long as it is stored in a cool place, it can last for up to a year after opening, but something caught my eye: if the bottle is half empty, the lifespan goes down to 6 months. That got me thinking, what if I were to vacuum seal the fixer (I have these vacuum sealing containers normally for use with food), removing any air that would normally react with it; would this extend it's lifespan more?
It's probably more work than it's worth, but I'm just curious.

Search the forum. We just had a conversation about wine bags about 4 weeks ago.

Oop! Looks like google failed me, I'll check that out.

Just decant to smaller bottles with good lids - sparkling water bottles are a good choice.
Wine bags are great for developer. They may be overkill for fixer.
Most people mix up fixer to working strength, and then re-use that working strength fixer until it approaches capacity.

I don't think fixer goes bad with exposure to oxygen. I say that because I took a 1yr hiatus from shooting and developing and after a year, the fixer was still good enough to clear TMX in 4 minutes. It did acquire lots of particulate matter though, so If you do this, make sure you have one of those funnels with a strainer on it to remove the particulate.
