Nitrogen System for Dust Removal and Chemical Preservation

........... the nitrogen, s................ JMHO[/COLOR]

What the....how, where, why did color dodads apear? Did I do dat?

It does not work on mine.

has anyone mentioned wine preserver for topping off chemicals? that's what I've been using for a few years. comes in big cans. Does it work? yes. is it the right gas? I dunno. Sure, I've had kodak e6 kits a couple years past exp dates which still worked just fine.
I would NOT use dust-off as it often shoots out liquid.

I like topping off with wine.

I don't trust those things to preserve the wine... it's best just to just finish it

How long would 1L of argon last you PE ?

I would not use Argon, as it is too expensive.

Also, these are only liter sized with no indication of pressure. So, who can say. Probably months if not a year or so. Depends on how active you are in mixing and processing.

Sorry that I can't be specific but this is too open ended.

Sorry for my late reply PE. Yes my question was certainly too open ended. I have since established that the pressure in the 1 and 2 litre disposable welding gas canisters is at about 110bar meaning they hold 110 times their geometric volume when the gas expands to the lower pressure of one atmosphere.
At this small container size, argon does not put the price up prohibitively since a good proportion of the cost is the bottle. From what I've been able to understand, the main advantage of argon is that it is heavier than nitrogen and air which can 'blanket' the chemical's surface.
I found the following an interesting read

Yes, Argon is heavier, so use it by all means if the cost is suitable.

Do not use Carbon Dioxide.

And with your figures above, you can calculate your use rate better than I can.
