HC 110 'H"

[frank]

How often do you agitate, and what benefits do you get from this regime? I'm almost 80% HC-110 dilution H but am intrigued.

agitation: 1 minute continuous initially, 1 minute half way through, dump after 50 minutes. this works for HP5 and Tri-X, various lighting conditions on same roll

benefits: it's easy, I'm lazy

I have used Dilution H for about 10 years now and have never had a bad roll in that time. My understanding is that because Kodak formulated HC-110 with no water in the mix, it is very stable. As soon as you dilute to taste, it becomes less stable. It is perfectly possible to use replenished, but why ? It is cheap and efficient. Just my view.

I knew I'd get jumped for throwing fixer away after using it to develop film but I cannot remember doing otherwise years ago...maybe I did and just couldn't recall doing more than one or two rolls at a time. I use to do Cibachrome a fair amount long ago and you could reuse the developer but for more stable prints it was recommended no to. I did reuse it on prints that weren't that important but other I wanted to last as long as me or longer I used undiluted or over again.

I'll save the fixer next time but it seems wrong to pour used fixer back into the same bottle with fresh fixer.

Why would you do that? I use TF-4 fixer. I keep the gallon of liquid concentrate on the shelf and mix it 1:3 with water to make 1 liter of working solution that I keep in a 1000ml capped brown chemistry bottle. I pretty much use that whole liter of fixer each time over and over in my 1000ml SS development tank. So no used fixer being mixed with new. After about 20 rolls or so, which for me is about a month or two, I mix a new bottle of working solution. Sometimes I find out when some rolls come out grey and under fixed. No problem. Re-spool and dunk in some newly mixed working solution of TF-4 fixer. That all said I am lately using a Jobo tank and need only 270ml each time for that. I use and dump it back in the same 1000ml brown bottle with the remaining 730ml I did not use that time. No problems.

I shutter to think of dumping such perfectly useable fixer down the drain after only one use!

I've always used Kodak's Rapid Fixer with the small bottle of hardener. the contents of both Solution A and B will make one gallon but I usually just make half a gallon at a time. I put that half gallon in the old style but newly bought accordion container, pour in 300 ml if I'm doing just one 35mm roll or twice that if doing two. With 120 developing one roll I'll use 500 ml then dump. I could find no where that Kodak says how many rolls can be processed using it again.

Haha. Thanks Frank. I'll give it a try some time.

I use everything one shot.

I may as well post a link to the Article I posted on APUG about how I test and use fixer: (there was a url link here which no longer exists)

The critical point is that I do a clip test for every roll I fix, and I pay attention to the manufacturer's recommendations on capacity.

By the way, I don't add the hardener to Kodak Rapid Fixer. I just replace it with the equivalent quantity of water.

The (diluted) hardener gets used on its own when I tone prints.

I fix the cut off film leader (of 135 film) in the cap of the fixer bottle filled with fixer, at the same time as the film in the developing tank is being fixed. Continue to fix for double the time it takes to clear.
