I just took home a "new" bottle (doesn't say Harman anywhere) of Ilford Rapid Fixer (CAT 198 4262), and what do you know, the darned thing doesn't clear New Tmax400 at all in the normal fixertest that I do. (1+4, 20something C). After 11 minutes the clipped leader is barely see-through. Is this normal? I'm afraid to use this on actual film (used TriX and HP5/FP4/PanF for a looong time).
The bottle is labeled "LOT: 21B008S", if it helps at all.
Also tried a few years old TriX, it cleared in 6 minutes or so, but stayed very pink. The pinkness didn't wash off.
I think I really should stop testing the fixer and just use it as I've always done. And then blame the messed up films on myself...
