Emofin - capacity and shelf live?

I'm rather new to Emofin and developed so far 12 films in the batch I prepared about 3 months ago. Stored in a glass bottle and spayed with butane gas. Now I had the impression with the last two films that the developer became less active.

Tetenal says shelf life 3 - 6 months and 15 films capacity. How are your experiances?

Many thanks in advance - Reinhold

My experience is that Emofin keeps very well. My current Emofin is prepared about half year ago and I haven't noticed any problem with it. Expect the change of developer's color.

I store it in plastic bottles.


It could be more the issue with film volume than shelf live?

I think the storage comments are generally correct. The batch gets re-used to an almost-coffee-looking condition. I'm about to mix my 10-year-old dry kit and will use with HP5...it was superb with Neopan 400. It doesn't produce Rodinal-looking grain therefore may not look as sharp as Rodinal, but doesn't look as "soggy" as TriX usually does (IMO)

I haven't really pushed Emofin beyond 10-13 films, so I cannot tell you if the 15 films limit really holds.
But 3 months should definitely not be a problem. I 've used mixed batches for a year and saw no degradation in development power...

I developed 20 films in a batch that was stored in plastic bottles. Didn't notice any changes in developer activity, but dumped it anyway because I got bored. Besides the developer was forming some kind of precipitate (the darkening mentioned in posts above) so I had to filter it several times during the course of its usage.
