Hello,
Does anyone happen to know the fixing times for Efke 100 and Tetenal Superfix 1 + 9 (fresh solution)? As I only want to use the film as a sheet film for flat-bed scanning, the standard method of determining the fixing time would waste a whole sheet. It won’t kill you, of course – but if it can be avoided, all the better. :D
Best regards,

Robert,
It doesn’t cost an EXTRA sheet!
You can simply use a standard sheet that needs developing as a test sample.
Development……Stop……Add fixer and start timing.
After about 1 minute, just check how far along the clearing process is and stop the timer until it has cleared completely.
Multiply that by two to get the fixing time.
But you can also just fix for 4–5 minutes.
Over-fixing isn’t a critical issue straight away.
I can’t recommend 1+9.
1+4 is better.

Hi Mirko,
Thanks for the tip.
I use the 1:9 dilution as a one-off fixative – I haven’t had any problems with it so far.
Best regards,

OK, as a one-off fixer, that works, of course.
But who’s going to lug the ten litres of used fixer that a bottle of Superfix produces to the tip for disposal????
You’re not actually going to tip it all out, are you.....
That’s why we recommend 1+4.
It fixes just as many films and is easier to carry to the tip :rolleyes:

Hi Mirko,
No, I don’t just tip it away… If that happened at home, I’d have two large kitchen knives in my back in a heartbeat and my last roll of film would be developed!
But seriously – my 35mm films produce 250 ml of fixer waste (tipped away), and I’ll probably use about 300 ml for the sheet films (the stated 260 ml seems a bit tight to me). I’m allowed to hand over up to 30 litres every six months at the hazardous waste collection point – without paying – so that works out at around 100 developments. I’d be happy if I could manage that ;-)
I have to go there anyway...
Best regards,
Robert
