Some scanned-in negatives off of a roll of ISO 400 black and white film:
but they can also melt things too:
That’s two metal racks that normally sit in the autoclave, joined together by the plastic remnants of a bin that didn’t have a high enough temperature rating. The culprit was someone from the lab down the hall – it happened about 6 months ago, and they still haven’t bothered to chisel it off to make the racks useful again. Of course, that’s how long it for me to drag my camera in and take a photo of it.
More to come, whenever I get a chance to borrow my friend’s neg scanner again.
