HC-110 equivalent

I think that Kodak recommended self replenishing when they stopped making the replenisher. You would discard some of the old developer and add enough fresh to restore the volume. Check with Kodak's website for specifics or their customer service.

BTW, they deiscontinued the replenisher because nobody was buying it.

I'm making a densitometric plot chart of HC-110 with what's left of my HC-110 R. I am then making a plot with the Legacy 110 R and the Ilfotec HC replenisher. I will compare my results and see if either can be used as a replenisher for the remaining HC-110 developer.

I use HC-110 as one shot developper and it goes just fine. So I have no idea how to use a replenisher (on the Freestyle web, there is no info about it either) and is it worth it?

I wouldn't suggest replenishment unless you are running a very high volume of film and want to focus on cost efficiency over quality.

Thanks for answering. I use one HC-110 bottle a year, amongst other developpers like D76 & Rodinal.

Some people used to use HC110 replenisher as a developer for pushing Tri-X to very fast speeds. You can find some info on this with a Google search. This is less popular now (was never that well known) that films like TMZ and Delta 3200 are available, though I wonder what it could do with them. I don't know if the Freestyle Legacy Pro brand would work for this; they do make replenisher. I'm tempted to give it a try. One formula I found was to use HC110 replenisher at 1+15, for 5.75 minutes at 75F, for an EI of 5000 with Tri-X.

There is NO exact equivalent for HC-110. Ilford makes a developer that is similar but not the same. So there is no way to really mix the developer of one company with the replenisher of the other. Freestyle Legaacy Pro L-110 which has been mentioned in this thread and in others as a substitute but is not even close to HC-110. All you have to do is look at the two MSDS's. They really need to stop suggesting that they may be the same.

Kodak suggested a self replenishment system but never elaborated on the idea. So you are limited to using HC-110 as a one-shot or doing your own testing with self-replenishment.

Fair enough, but I'm still thinking about trying the LC110 replenisher as a pushing developer. At worst I waste a bit of chemicals, buy a bottle I have no use for the rest of, and a bit of film.

Use it one-shot (I usually use Dilution B) and discard. You'll get very consistent results this way, and the cost of your developer will still be very low per roll.
