the Arista/legacy Pro L110 is also less viscus and easier to pour. It is made in USA, I believe by Unicolor, (Photo systems INC) I wonder if KodakAlaris is switching suppliers to the folks who make that, for fear of the German change of control at Tetinal? from what was written about HC110 in the past, some of the intermediate stages are almost explosive before the reactions all settle down.
photo systems also seems to be the supplier for the rest of Freestyles range of "Kodak Chemical Clones" which all "work the same" but may not be identical.
Sadly, I tend to have to get my supplies by Mail order from the US, so I end up with th eUS market stuff.
Minor correction Ron since people will be referring to your remarks on this subject for years to come, I think you meant DEA not TEA in this case.
I know of no hint that Tetenal ever made any synthesis beyond a plain adduct. I would appreciate to learn the contrary.The DEA-sulfur complex is a little hard to make, but Ilford and Tetenal have both managed to do it.
The bottle I bought today (Made in Germany, no "new formula" on label, not looking like the new bottle on B&H) has this catalogue number, yes. This matches also the old version catalogue number at B&H.Would someone verify that the old catalog number of the thick yellow syrup HC-110 is 5010541? When I last bought it, I decanted the stock into smaller amber glass bottles and recycled the original container. I just bought 3 bottles to ensure I have enough for the amount of Tri-X I have in the freezer and want to ensure I'm getting the old formula. I doubt that the new formulation is even in the general supply chain, yet, but thought I'd verify anyway.
Thanks!
The DEA complex is the adduct by another name.
It is confused by non-chemist reporting in the press and by others.

True enough.If it's not viscous, it's not HC-110.
Out of interest, how dangerous is the process of manufacturing the adduct? Going by your comments here, I take it that it requires a specialised/ dedicated reactor vessel that is presumably considerably more costly than the setup necessary to manufacture D-76 or Xtol?
Officially the stock solution of HC-110 has a shelf-life of 6 months when stored in full, tightly closed bottle. So as long as the new formulation meets this, from the pov of producer it's as good as the older formulations.
I believe that figure is when mixing a stock solution from concentrate.
I have two concerns. One is whether the new HC-110 will have the same shelf life as the old version.
I don't have to shame you. You just publicly shamed yourself with that sentence from the end of post #88....you're not going to shame me for tipping what probably amounts to 4 litres per week of D76/Ansco130/D72, Ilford rapid fixer and heavily diluted Selenium toner, down the drain
I seriously doubt that I have publicly shamed myself by describing what the vast majority of B&W workers do with their used chemicals. Please enlighten us as to how YOU dispose of your B&W chemicals.I don't have to shame you. You just publicly shamed yourself with that sentence from the end of post #88.
