Hi Shel, Yes, you'd think spores in a new bottle might get activated and start multiplying as soon as the first batch of a suitable liquid medium was added to the bottle. You're right -- it could be a recent "infection". Also not out of the realm of possibility that one or more of the chemicals used to formulate the ID-11 batch were contaminated. Finally, I suppose it's possible that Ilford inadvertently released a manufacturing lot of ID-11 that was improperly formulated. Maybe they didn't add enough sodium sulfite, or didn't add as much as past batches you've received? (Their MSDS lists 60% to 100% sodium sulfite -- that's a pretty wide manufacturing tolerance.) Maybe they really goofed and used some other salt instead? Don't know what the likelihood is that such a thing could happen, but I suppose there is a ~small~ chance. You might want to try making a new batch of solution using Part A from your suspect lot and Part B from a different lot. I'd bet that if you have any of the suspect material left over, Ilford's quality control folks might like a sample. I'd also bet they'd be willing to replace the developer you purchased from that particular manufacturing lot. Bill Peifer Rochester, NY - This message is from the Pentax-Discuss Mail List.
