View Full Version : HC-110 usa v euro

01-28-2008, 08:41
Ive just bought a bottle of hc-110 to try out as im getting too stuck on my neopan+rodinal developing and i wanna try something different. The bottle i bought is a plastic 1 litre euro? bottle and before i go develop ive run into hurdles such as usa dilution and euro dilution and dilution a,b,c,d...etc.
Ive tried to search rff for direction but the function aint working.
I either shoot neopan400 or hp5 and would love some help with this developer before i go messin anything up :confused:

Look here:

Scroll down and there is info regarding the differences and dilutions for Euro vs. US market concentrations. Good luck, and enjoy. BTW- out of curiosity- what is your Neopan/Rodinal reginem? What time, temp, dilution do you use, and how does it look?

Thanks drewbarb. I shoot neopan@400 and dev 1+50 at 20c for 11mins. Agitate first min, then 4 inversions every min there after(just like the massive dev chart). Results are fine for me, but im getting a little sick of rodinal's sharp tendencies.

A note: I've bought 'U.S.' HC-110 in Europe (Sweden, if it matters). Remeber to compare the dilutions on the bottle with those given at Covington Innovations above to see which you get.

Hi there.

My results with HC-110 and Neopan have been very satisfying. I rate it at EI 200 and develop 9 mins at 20c (dilution H). 30 sec agitation to start and 2 gentle inversions at the start of each following minute.. I love it !!!

BTW, this is what you need. the more concentrated version. It keeps a whole lot longer than the dilute EURO version.. 1:63 dilution of this syrup will make the unofficial DILUTION H. Best measured with a syringe.


Regards, John.
