How many roll does a 1l pack of Perceptol last ?

[hans voralberg]

I'm trying to stock up for my trip to SEA and Perceptol will be my main low speed dev, but I havent used it before so you guys have any rough estimate of how many roll 1l might last ? Is there any minimum amount of dev that must be in the tank ?

Ilford have times for 1+3 dilutions. So, 3 litres of working dev. So, maybe 10 x 35mm films?

Searching here, it seems some people use it at higher dilutions, so it might be possible to eke a bit more out?

At 1+3 (which is my preferred dilution these days), assuming 300ml per film, you'll be good for 13 rolls of 135. I've used it 1+5 in the past (which gives a cool 20 rolls of processing) with no ill effects. I've heard of folks going further, but 1+5 is as far as I've tried.
