To Query Kodak (U.S.) on Chemistry Product

[AgX]

Wrong, Kodak Alaris got all production facilities for silverhalide still photo materials, except for still film, which is made for them by Kodak. (The precice deal never got published.)

The whole Kodak thing is even more complex with even Agfa joining. Important for the user is always the manufacturer stated on the package, whether that is the physical producer or not.

Not at all. The AGFA APX 100 that I ( and many others) loved, was made by AGFA; the current product sporting the same label is DEFINITELY not the
same film, regardless of the label.

With my post above I referred to any liabilities.
You cannot complain at Fuji or Ilford Photo about any AgfaPhoto film.


And contrary to what you say the current APX, Vista or Precisa films do NOT even have the Agfa name, or the Agfa rhomb.

Whoops! https://www.bhphotovideo.com/c/product/1000304-REG/agfa_ap6a4360_apx_400_professional_135_36.html

Let's check that again.

As I said, AgfaPhoto instead of Agfa and a dot instead of a rhomb. Completely different company.

Similar as with the two Ilfords in past.

Well, surprise!. I did get a response from Kodak Alaris in Rochester today by their "Worldwide Photo Chemicals Product Manager." He provided an initial answer and later corrected it. FYI, the first response:

HT-2 was approx. 3.5% acid solution. Indicator Stop Bath makes approx.1.5% acid solution when diluted according to the product instructions. Altering the dilution of Stop Bath to 1:25 (parts concentrate: parts water) would make approx. 3.5% acid solution. We do not know what precision is needed but the hypo test is a visual spot test to be used as a “rough guide”, so it should be OK. [Notice there's no mention of the possible effect of the indicator in the stop bath on the test result.]

The corrected response:

I should revise my answer -
The hypo test contains silver nitrate which is absent in the Stop Bath. Best to mix according to the formula and buy the ingredients (available in small quantity from a lab supply).

So, I'll get the Formulary Residual Hypo Test from B&H (same price as PF but much less shipping cost).
Thanks, all, for your comments.
