govi_padmavijayam Posted February 8, 2015 Share Posted February 8, 2015 <p>Hello all,<br> I have a bottle of each of Solution A and B and notice that crystals are formed at the bottom of each jar. They appear to be flaky crystals. Are the solutions ok to use ? I fear that when I pour them in the dev tanks, the crystals will bruise the film and leave scratches as I agitate the tanks. <br> Have any of you noticed this ? How do you recover the developer ? Would filtration work - would I lose any 'potency' in the developer if I filtered each of them into other bottles ? Is there a way to prevent crystallization from happening ? <br> With the current cost of Diafine, I would like to extract as much as I can from what I have before I discard it. I'm checking Rodinal out for developing my low speed films and am getting used to the developer.<br>Any insight / experiences would be greatly appreciated, as always.<br>Best -Govi</p> Link to comment Share on other sites More sharing options...
larrydressler Posted February 8, 2015 Share Posted February 8, 2015 <p>Just filter them out. I have seen this before.</p> Link to comment Share on other sites More sharing options...
lex_jenkins Posted February 8, 2015 Share Posted February 8, 2015 It's a good idea to filter or decant Diafine to a clean container occasionally because sludge from reuse tends to accumulate in the bottles. Link to comment Share on other sites More sharing options...
chrstopher_walrath Posted February 8, 2015 Share Posted February 8, 2015 <p>Yeah, if it acts anything like Rodinal, you need to refilter the solutions occasionally as sediment will settle and, if allowed to sit for a long enough amount of time, crystallize. Empty the solutions into a clean container, filtering through a coffee filter, clean out the original container and put it back in. Good as new. I would think this would be pert near the same for Diafine.</p> Link to comment Share on other sites More sharing options...
glen_h Posted February 9, 2015 Share Posted February 9, 2015 <p>My darkroom is now about 60F, so I have to warm up my Diafine before I use it.<br> I would not be surprised if some crystalizes out at low temperatures.<br> My Diafine is almost four years old, and I might make a new batch soon, anyway.</p> -- glen Link to comment Share on other sites More sharing options...
