HC-110 single shot

[Jehu]

I was figuring that, instead of mixing the 1+4 stock and hopefully using it before expiring, I would try mixing single shot. The math says that it would be 1+31 using the concentrate to derive solution B which is what I like to use. Has anyone tried this? I don't see why it won't work but you never know until it's been tried.

I have been using J Brunner's approach since I started developing and have not found any reason to change. Look here for the details: http://www.jasonbrunner.com/hc110.html

I get 1:63 to get solution B from concentrate. i.e 1/4 oz to make a pint

1+3 gets stock solution. If I'm remembering right, solution B is 1+7. That amounts to 1+31. Did I miss something?

Yes. Get an accurate small graduate that will measure one ounce. Add that to 31 ounces of water and skip the middle man. To get all the syrup out of the small graduate add some water, put your thumb over it and shake. I've been using HC110 this way for 25 years, though I upped the dilution at some point so that I had longer development times in the summer heat.

The syrup seems to last years and years even in a partially used bottle in the fridge.

You're right.... I misread the small print gettin old.....


works out to 14.8 ml per pint.

What Kevin said.

You don't have to get a graduate if you have Vicks NyQuil, the measure cup is conveniently marked in ml, 30 ml approximately one ounce. I have several that I have saved over the years. A by product of being occasionally under the weather

Try a turkey injector, at every supermarket.

If you're finding dilution B too contrasty, try dilution H, which is dilution B mixed with an equal amount of water, or 1:63. Add 50% developing time as a start.

I use a dosing syringe (free at any pharmacy) to measure out the syrup. I mix 50:1 usually. I have never made stock solution with HC110; I use it just like rodinal.
