XTOL Concentrate

Since the smallest available package of xtol is 5 liters, is it possible to
prepare it as a concentrate and dilute as needed?

Some people say you can prepare it in half the specified amount of water. I
haven't tried this.

Preparing your 5-liter package in 1 gallon (3.8 liters) of water, and then
diluting it slightly,
would also be handy, since 5-liter jugs are uncommon in this country.

Some more Xtol lore is at www.covingtoninnovations.com/xtol.

You can try it but I would consider using a co-solvent such as alcohol or
glycerin to keep the contents suspended.

Would Scotch work?

5 litres into 500ml and 250ml brown bottles and into the fridge
(cohabits my "darkroom" with the enlarger etc.) seems to work for me...
or at least so far. No sign of the dreaded XTOL failure yet - but I
guess I won't recognize it until it's too late anyhow.

What's your estimate of keeping properties under these conditions? Any
percipitation?

I mix a 5 liter package in 3.3 liter of hot water with no problem. I then
split the content in small glass gingerale bottles that contain 300 cc each
topped off ( eleven bottles total- do not put them in the frig for obvious
reasons). At the time of use, I mix 1 part Xtol : 2 part water for standard
1:1 development times. Results look just fine. Much better than D76.

I have succeded in dissolving it in half the volume. Just remember to
follow the instructions which say to dissolve part A first completely.

Lew, I have insufficient data as of yet. This is my first go with the
5l XTOL package (I had a number of 1 litre packages to work through.)
I'm up to a couple of months with no preciptates yet and (apparently)
uniform dev. activity.

(though I doubt it will last as long as my Rollo Pyro which is pushing
four years now and still working fine...at least as far as I can tell.
When you only use a few millilitres of "A" each time, half a litre lasts
a long time - at least at my shooting rate.)
