After all the back and forth from and with Tetenal, I used up my old XTOL packs until 2020 in order to then use Mörsch chemistry exclusively. A test of the new US XTOL batch with a TX400 35mm film amazed me because the film did not reach its sensitivity or maximum density. I haven't tested another batch yet or testet films accurately to the new batch. What is your experience with current XTOL chemistry? Sino Promis XTOL was unusable and I haven't used Adox XT3 yet and don’t plan to for now.
See edited, combined post #4Perhaps coincidence, or perhaps user error on my part, ....
Another Xtol failure?

I assume you haven't seen #4?

So basically what's going on?
Time is moving faster than responses are being posted. It looks as though the OP has moved on.

All the bags I got from Sino Promise so far have been fine...
The current batch, made in US, is not usable, as, after a retest, TriX and Tmax400 are coming out underdeveloped with our time. We would therefore have to retest all films. A test of 0.1 over fog showed a lower sensitivity for both films.
No, because the Chinese powder hardly dissolved at up to 30C°. And higher temperatures are absolutely not recommended, as the vitamin C derivative is damaged.
But... once I've used up this stash, I won't be using XTol, or that XT-3 substitute, when I can easily mix up XTol-like developers from scratch.
I’m curious if anyone on here uses a densitometer when testing or if everyone is eyeballing it off of scans?
I’ve been having a similar issue, not that it’s really an issue if you test for it, for the last year or so with XTOL (Kodak and the eco pro variant). Developing with XTOL 1+1 @ 20°C with inversion agitation every 30s for 400TX in 35mm requires a time of 13m30s to achieve a 1.25 range from zone I thru zone VIII. My base fog is 0.19, I is 0.29, and VIII reads 1.57 (close enough to my 1.25 target). This is considerably longer than the data sheet recommends, but the curves essentially match my old tests (2020) which were done at 10m to achieve the same range. Grain is similar and outside of taking longer everything is great.
I go through a full 5L bag of XTOL every month and XTOL has been this way since at least last summer. I changed darkrooms recently before that and assumed it was just something in the new water, but since I work out new times when I change location or chemistry it didn’t bite me.
Totally understand OP not wanting to test all of the different film stocks, but if you were at 10m and now you’re at 13m30s like me, you could try one other film at 35% longer than your old times and see if it’s on target. If so, you’re probably fine to use that time formula for all other films.
