ron_west1 Posted September 12, 2006 Share Posted September 12, 2006 Hi,I plan on using Ilford Rapid Fix deluted 1+4 to fix my 35mm film. Ilford statesthat the deluted solution will only keep for 7 days and will process 24 rolls of35mm/36exp film per litre. Reading through old posts it appears that mosteveryone is reusing their fixer until it is exhausted but surely they are notprocessing 10-24 rolls of film in 7 days? Will deluted fixer 1+4 keep longerthan 7 days in a partially filled bottle? Please advise as I hope to reuse my deluted fixer for longer than 7 days!Thanks, Ron Link to comment Share on other sites More sharing options...
chris_waller Posted September 12, 2006 Share Posted September 12, 2006 I keep my diluted fixer in a bottle (dense plastic) for weeks. As long as the air is excluded and it doesn't get too hot, it will keep. My fixer is discarded due to exhaustion, not old age. Link to comment Share on other sites More sharing options...
evan_goulet Posted September 12, 2006 Share Posted September 12, 2006 You'd be surprised how much some people shoot around here. If you are keeping the fixer, it is best to have a bottle that is approximately the same volume as the fixer you have. This will help minimize exposure to air.

AaronFalkenberg Posted September 12, 2006 Share Posted September 12, 2006 Although I'm not sure about how it will keep in a partially filled container, I wouldn't worry about it going bad. It generally lasts somewhere around 6 months, maybe more. More importantly is knowing when it is actually exhausted. I asked a fixer question a while back and was told about Edwal's Hypo Check. A couple of drops will instantly tell you if your fixer is saturated with silver. If you are using a hypo clearing agent after fixing (highly recommended to reduce wash times), you will want to make sure it is not more than 3 months old. This is one chemical that goes stale rather quickly. It's so cheap in volume, I use it in single shots, but it can also be reused. Link to comment Share on other sites More sharing options...
leicaglow Posted September 12, 2006 Share Posted September 12, 2006 It will go for much more than 7 days, but of all the fixers I work with, I believe the Ilford RF has the shortest shelf life after being mixed. Link to comment Share on other sites More sharing options...
frank.schifano Posted September 12, 2006 Share Posted September 12, 2006 I can't say with any certainty about Ilford's Rapid Fix, though I have not yet run into a situation where a batch of working strength fixer has gone bad on me due to old age. Often, a batch of film strength working solution fixer (1+4) will last me a a couple of months before it's exhausted. Paper strength (1+9) working solution may not last as long, but that is usually used to what I consider exhausted long before that much time has passed. If you are looking for a long lasting, inexpensive, and very efficient fixer look to Kodak's Flexicolor Fixer and Replensiher. Though designed for the C-41 process, it works as a standard B&W rapid fixer every bit as well as any other rapid fixer I've used designed for B&W only. I use it at the recommended dilution for films and twice the recommended dilution for papers the same as I'd use any other rapid fix. If you decide to try this, do avoid the Kodak Flexicolor RA (C-41RA) Fixer & Replenisher. The RA version of the fixer is not good for B&W materials according to one who posts here regularly and whose opinion I value. Link to comment Share on other sites More sharing options...
jim_appleyard Posted September 12, 2006 Share Posted September 12, 2006 Hi Ron, some folks shoot tons of film! 2-3 times a year I will shoot 10 rolls in a day. Although most of the time, it's 1-2 rolls a week. Link to comment Share on other sites More sharing options...

As in Hypo-Clear, is that the stock solution or the working solution? Link to comment Share on other sites More sharing options...
AaronFalkenberg Posted September 12, 2006 Share Posted September 12, 2006 It is 1L stock solution of Kodak's HCA. I store it in sealed 250ml brown plastic pharmaceutical containers. From that I use 50ml of solution in 200ml of water for working strength and toss it after use. I had three containers of HCA left that were older than 3 months. I used one of them (that's 4 rounds of 4 sheets) and found there was residual fixer as well as T-Max dye left in the negs. Because the HCA was stale, my normal wash was severely insufficient.

ron_west1 Posted September 12, 2006 Author Share Posted September 12, 2006 Thanks Everyone, Will get some Hypo Check, Hypo Clearing Agent, 4x250 bottles and a 1 litre accordian bottle and give it all whirl.....Thanks again, Ron Link to comment Share on other sites More sharing options...
neilpeters Posted September 13, 2006 Share Posted September 13, 2006 I always use fresh hypo on film, then it goes to the darkroom for paper, never the reverse. Link to comment Share on other sites More sharing options...
gene_e._mccluney Posted September 17, 2006 Share Posted September 17, 2006 I use Kodak rapid fixer with hardener. I used to keep a 3.5 gallon tank full for processing of 4x5 and 8x10 negatives. That tank would last a year or more. I now keep a gallon bottle of "film dilution" ready to process my Leica b/w films. It lasts for months.

mike dixon Posted September 17, 2006 Share Posted September 17, 2006 Fixer doesn't oxidize the way that developer does, so minimizing its exposure to air isn't so important (though you don't want it to evaporate). Diluted Ilford Rapid Fix remains effective for much longer than 7 days (assuming it hasn't been exhausted from fixing too much film). Link to comment Share on other sites More sharing options...
