Hi, just wondering if anyone can help me, I've bought, Ilford ID11 Developer, Ilford Stop Bath, Ilford Rapid Fixer and Ilfotol Wetting Agent. The question is, i think the developer is single use only once made to stock and the wetting agent will be only used once, as will only need a couple drops when washing at the end, but what do i need to do with the stop and fixer?

Last time i did any processing i was at college and everything was already prepared for us to stock so i'm a bit sketchy, can get my head around mixing up the ID11 to stock and then mixing that up to use, but do the stop and fix have to be diluted to stock, and then diluted again to use or is the bottle stock? and are they reuse, or single? i think we reused them at college, but we didn't know the actual products we were using, just have a piece of paper on the wall giving times for HP5 for them!

Sorry hope that isn't too confusing or long, but would be really glad of some help
 
I used ID-11 and Kodak D-76 (same thing) diluted and used extended dev times to compensate. You get much smoother negs that way.
If you use it stock then it's multi-use - use the manufacturer's guidelines - you have to extend dev times gradually to compensate.

I found that too much effort - it's a good, cheap multi-purpose dev and using diluted gives the best results anyway, so use it once then bin it.

Store it as stock solution and only dilute it prior to immediate use.

Fix and stop are multi use - you'll know by the colour when to swap them out...lol

I used to rinse with water between each step as well, as the chemistry last longer that way because there's no forward contamination.
 
I had pretty good results with ID-11 used as 1+3 (1 part stock solution - the litre of stuff produced from the chemicals, to 3 parts water) as a one-shot developer. Make up the stock solution, store it in a squeezy jar so it's not exposed to air, and only make up the working solution just before developing your film. There are time guidelines for 1+3 widely available. Only time I used 1+1 was for pushing film, as it could quickly run into 20 minutes+ of standing around waiting.

Otherwise, what Rob said...
 
ah kk, thanks for the info. If i'm going to reuse the fix and stop then i think i'll need another bottle, as i got a 1 ltr compressable for the dev and another spare, so can put one of them in this when mixed up and in use, but for the other i guessing it'll need to be a proper chemical storage bottle, or would a drinks bottle or something do as a v.tempory measure? As i'm not sure where to buy one with out ordering! else is there anything else that could substitute an actual photography branded one?
Thanks

I used to use big square 5l drinks bottles for longer storage - more than a week.
Get a plastic pedal-bin bag and push that through the neck then inflate it on top of the solution - that takes care of the oxidisation problem.
Keep all your bottles on a plastic drip-tray or spare print-dev dish to minimise spillage. Crusty dev residue is nasty.

Don't throw used chemistry down the sink - it's illegal and buggers-up your pipes.
Put it in big 5-gal containers - seperate ones for each type (stop-bath can go down the sink as it's basically vinegar) and contact the local council for details of specialist waste-disposal contractors in your area.
This was a big PITA for me at the last place we used film: getting the chemistry removed. Costs a fortune, though if you're a domestic user, you'll probably only need quarterly or six monthly collections.

Those drums must be stored properly in a properly marked shed or garage with the requisite stickers displayed.
Think I'm making this up?
Took me a month to get my head round all the H&S and COSSH requirements of what we did with film and print chemistry.

Councils do spot-checks on the stuff coming down the sewer, so don't get caught out.
 
ah right, i'll need to have another think about this i spose, i guess if i'm reusing fix and stop i'll only need to collect developer in another container, and it wont be much... i might manage a film every couple of months i guess, so i might get a litre a year collected, think i'll have more of a problem with the stuff going off before using it. at college we just put it all down the drain, but i guess it might not of been a usual drain, it was just for the darkroom, so might have been collecting somewhere else
 
I think if you're just doing one film a month, then by diluting it massively (chuck it in the bath after you've finished bathing), then it'll do no major harm...
But I didn't tell you that...

We were going through about 600 rolls of 35mm a week using three Jobo processors, so there was a lot of waste chemistry going down the drain before I arrived and sorted things out. We had to replace all the rotten piping, install collection points with a stand-alone system seperate from the normal water drainage system and build a waste-chemical 'bunker' to store the drums...
I managed to convince the bosses that doing all that and paying for the collections was cheaper than getting fined by the EPA...
 
whats it likely to do to a septic tank in smallish quantities?

thinking BnW and E6 chems for when I set something up at home

If it's plastic - nothing...
If it's an older metal one, then again, in small quantities nothing - in the amounts we were using - lots...

I think for domestic use, 1 or 2 films a month, then as long as you dilute the dev properly, i.e. two or three flushes...then putting it down the soil-pipe is probably the best bet, rather than the sink, even if it goes to the soil-pipe eventually.
Dev residue is horribly corrosive.

Disposing down the sink/toilet is frowned upon if not actually illegal (depends on the County you're in, I think as the water-treatment systems vary from region to region).
You should really save it and send it away for the silver to be reclaimed...

This was a really HUGE issue for the MoD from 2001-2003 and actually hastened our conversion to digital before it was a fully-proven system for us...
 
well its plastic and on our land so should be ok, odds of me getting round to it anytime soon are slim tbh
