HC-110 minimum amount of concentrate per roll?

I'm sorry if this question has been answered a number of times but I

searched the archives and couldn't find the answer.

 

With HC-110 what is the minimum amount of concentrate (syrup) that

you need to properly develop a roll (35mm, 120, 4 sheets of 4x5 or

equivalent) regardless of dilution? With Xtol, for example, it's

necessary to have at least 100mm of stock solution per roll. I want

to try some thin dilutions of HC-110 but need to assess that there's

enough developer to handle the process.

 

250 ml of dilution B (1:31) has about 8 ml of concentrate, should I

use that as a minimum or can it be stretched thinner?

I'm going to go ahead and say 3ml of concentrate per roll of film is the minimum.

The consensus seems to be that 3 ml is enough. Works for me, at least. Developping sheet film in rotary processors with 100-125 ml of this soup brings me very close to this 3 ml limit and I never had any problem.

Jon, Philippe, thanks for the replies. Yes you are right; after posting my question I remembered having processed in my CPE-2 with 125 ml of HC-110-B solution. So, if I go to a high dilution I just should keep the amount of concentrate over 3 ml per roll, right?

Yes process with higher volumes rather than less concentrate. For people using reels, develop one reel in a two reel tank for example.

I concur---3 ml per roll or equivalent.
