    Butane for developer preservation

    I have seen this posted various times and happened on someone else's unused Ronsonol lighter fluid in the house today. Is this the same stuff, or am I looking for a gas? I haven't a clue.

    Thanks.

    I believe butane is a gas at standard atmosphere. Butane lighters store it under pressure. Ronsonol lighter fluid (yellow can) is naptha.

    Butane is definitely a gas. Lighter fluid is not.

    A free source of inert gas is your breath... Take a drinking straw and blow a big exhale into the airspace of your developer storage bottle... The CO2 displaces oxygen, and my stock solutions are good for months...

    breath still has much oxygen. We are not efficient about the conversion because CO2 is poisonous to humans. CO2 is acidifiying, but not much. Ask the coral.

    If I was going to spray a gas into a developer bottle to drive the oxygen out, it wouldn't be flammable. Save the butane for fancy cigarette lighters.
    In recent times, I've used two methods to deal with developer oxidization; 1) one-shot mixes from a concentrate (Pyrocat in glycol) and previously, XTOL stored in 500ml brown glass bottles.

    This has been my method for decades, best if I can hold me breath a long time, as the percentage of CO2 increases. Decades ago, there was nitrogen in a can (still available for wine drinkers), but that's not in my budget, either for wine or my print bath, so I was just wondering about something better, since my darkroom time is a bit more spread out now.

    (I do decant into smaller bottles as volume goes down as well. I can buy a gallon of my print developer with free shipping for the cost of 2 quarts [plus shipping]. It goes into top-full quart containers.)

    Or glass marbles to raise the chemistry level.

    Wasn't that dust-off spray Omit once claimed to prevent oxidation of chemicals. Now I remember, that stuff was Freon. Probably long removed from the market. Maybe the new AC gas they sell in Walmart would work.

    Instead of explosive gases, leave the BLOW-UPS to optical magnifications under the enlarger.

    For glass bottles -- which can't be compressed like plastic bottles can -- marbles are great. You can get large bags at the 99 cent store. If the tops to your bottles are too small, the local hobby/floral/home decor store will have smaller marbles for floral display purposes -- at higher prices.

    I avoid all this hassle by mixing only what I need at the time -- it's always fresh.
