Butane for developer preservation

[Duolab123]

The stuff that Tetenal sold was/is a mixture of propane and butane. Bic lighters contain iso-butane, gas is heavier than air, so is propane. I would use one of the long lighters except I'm afraid I will accidentally pull the trigger and blow up the bottle of chemistry. My wife has a neat little refillable butane torch. I use that to flush out the air, no ignitor.

Small bottles with tasty beverages almost for free, and no explosion risk, works for me!

Butane is just a bad idea

My wife has the best suggestion of all: Take my chemistry bottles to the Costco auto shop -- they fill the tires with nitrogen.

The one around here is actually self-serve now. No idea if it's nitrogen but you could be on to something if it is. Of course if you forget to set the PSI very low your chemistry bottle would likely explode.

Actually a good idea

Free N2 at Costco, my 4 trailer tires go to 70 PSI

However it will stink from the odor the tire puts out, which is horrible

I had real stinky Winter Tires, when I put them in the hatchback I HAD to drive with the windows open

I just fill bottles to the top. Last Butane I used was splitting Tetenal E6 chemicals several years back. It did work well. Years ago Sam's club sold computer dusters that used straight hfc-134a. Bad news for global warming. Now iso-butane is used as refrigerant in household refrigerator/freezers.

I decided to check out how much error was introduced to the developer stock solution if I just mixed up the Xtol and topped off the bottles. I used a calibrated graduate for the test. It turns out that the 500ml bottles that I use hold 510ml. 2% more dilute. Insignificant. And extremely consistent with the added benefit of extending the life of the developer solution because I only have a “bubble” of air in each bottle.
