We have improved the ADOX APH09 product.
The aim was to increase the concentration and adjust the formula so that the new standard dilution is 1+50, allowing development times to be adopted on a 1:1 basis from comparable products.
For all films tested to date, the results are identical in terms of measurement.
The new version is due to go on sale at the beginning of April.
We are therefore now selling off all remaining stock of the old version of APH09 (1+40 standard dilution) at a special price.
[size=2]The price per 1000 ml bottle is EUR 6.90 plus VAT = EUR 8.21.[/size]

Hello Mirko,
Does this mean that films developed in APH09 'New' are identical to those developed in Rodinal, or that only the processing times are the same and the slightly higher grain accentuation with APH09 'New' remains?
I’d be grateful for your reply.
Best regards,
Oliver

Hi Mirko,
I’m not sure either...
Are the development times for APH09 NEW the same as for APH09 OLD, or the same as for Rodinal?
APH09NEW = APH09OLD = RODINAL
or
APH09NEW = APH09OLD
or
APH09NEW = RODINAL
Thanks for your reply
Regards
Maik

Hello Oliver, Hello Maik,
At the moment, whilst the development times can be carried over from Rodinal, the dilution has always been different (1+40 APH09 vs. 1+50 Rodinal).
We have improved this. The composition of APH09 remains largely unchanged, but the concentration and pH value have been adjusted so that the same times can now be used with the same dilution to achieve the same density.
If you previously noticed differences in the results across different concentrations, these should still be visible afterwards.
At the moment, however, we are still selling off the last 1,000 litres of the old quality at a super special price!
A new table will be available once the new quality is on the market.
Best regards,
Mirko

Hello,
I bought a bottle of APH09 in the shop today and wanted to know whether this is the ‘improved’ version.
The label still shows the old dilutions, which made me a bit sceptical. There’s a small sticker on the bottom which I think indicates the batch number: 0832.

Hi Robert,
It’s good that you’ve asked again.
Everything sold at €6.90 is the old batch being sold off at a clearance price.
The new batch will be more expensive (due to the higher cost of raw materials).
Unfortunately, product development is taking a while as our old Sensitizer has broken down. We have determined the concentrations and obtained similar results, but for fine calibration to ensure everything is spot on, we absolutely need a Sensitizer – the Nikon won’t do the job anymore...
We’ve bought a new Sensitizer, but it still needs to be calibrated. However, due to the holiday season and the ongoing MCC project, I haven’t yet had a chance to sort it out. I hope to get it sorted by mid-September.
Fortunately, we still have plenty of the old quality in stock, and it’s sooooo cheap that the ‘upgrade’ from 1+40 to 1+50 is really worth it.
Best regards,
Mirko

So the new version isn't available yet? Does that mean something went wrong when I paid €11.90?
MirkoBoeddecker
Yes, unfortunately.
The invoice should also say 'old quality 1+40'.
Bring the invoice with you next time – we'll credit you for it.
Best regards,

Hello,
I’ve got a bit of a beginner’s question to ask (which only partly belongs in this thread). I’ve got a bottle of “old” APH 09 here that’s been sitting unopened since around April. Yesterday I used the developer and, when I opened it, there were loads of dried crumbs in the lid (or rather, the plastic inner lid).
There are an awful lot of dirt inclusions on parts of the developed film (the contrast and tonality of which are wonderful, just as I’m used to with APX100+Rodinal). On the inner frames in the development reel, roughly frames 1–10. At some point, this stops rather abruptly (see attachment). Was it ‘just’ that the film wasn’t properly wound onto the reel, or could it be down to the dried-out bits?
Thanks...

Hi Tilman,
In this post, I’ve tried to apply my approach to problems *and* a chemical analysis that meets a range of requirements. Depending on their own knowledge, everyone can now decide for themselves at what point they no longer want to read on :-) Let’s get started!
35mm film? Then one thing puzzles me: the smear is on the vertical edge of the image, i.e. exactly where the film really shouldn’t/mustn’t/can’t be sitting in the reel. Only with a vertically oriented APS medium-format camera would such a fault be possible with rectangular images.
Unfortunately, nothing more can be gleaned from the small preview image. Well, actually, one thing can be deduced: if the problem were caused by crystals from the developer (which it isn’t, see below), these would have appeared as a nuisance along the long edges where the film rests against the reel.
So I’d rather put my money on random grime or just the occasional shot taken with a dirty camera and possibly film canisters reused x times (the latter doesn’t apply to APS-MF).
As for the fizzing in Rodinal (and thus also APH09/R09 and whatever the clones are called), I can reassure you. Bubbling in the concentrate is completely normal and ultimately a sign of quality, indicating that the general cost-cutting frenzy hasn’t yet taken hold of the manufacturer. So that’s a good thing.
The concentrate has been prepared with a minimum of water for years (today, the manufacturer would tout this as ‘CO₂-reducing due to low transport volume’). Why do you think you can perform dilution to 1+50 without any problems? Exactly. There’s enough development-active stuff in it. Why do you think the solution lasts forever? Exactly. It’s prepared in a sufficiently concentrated form and formulated cleanly (see below). Consequently, some of it crystallises out if it’s stored below the preparation temperature of the concentrate. Rodinal comes as an almost perfectly saturated solution.
Crystals in Rodinal are not a problem and dissolve during dilution. It only becomes an issue with the larger chunks at the bottom of the bottle. These should be filtered out (using a coffee filter or a proper pleated filter; this is quicker and the 1+50 working solution lasts less than half an hour).
The crystals consist of p-aminophenol, which is the developing agent in Rodinal/R09. There is enough of it in the solution and, what’s more, it is brilliantly kinetically inhibited (take a look at the alkali component) so that this ‘excess’ does not cause any problems. Momme Andresen didn’t know this at the time, but he discovered it. Sometime before January 1891, as that is when the mixture was granted a patent and has since undergone only minor changes.

Hello Franz,
First of all, thank you very much for your detailed reply; I find many points of it interesting. To shed a little more light on my problem here, I’ve uploaded the image in question in a larger format here:
http://homepage.mac.com/tilman/filechute/a..._estremoz_2.jpg, for your perusal.
35mm: yes, the film was new in a fresh roll (received just last week from the supplier in a pack of 10). The camera is used regularly, including in recent weeks. No dirt whatsoever with other films (TRI-X). However, this was only the second roll of APX100 from this batch; the first was also heavily soiled, but I’d had that developed at an unknown lab, where there was indeed a lot of dirt and unknown water, so I understood that. Your information has now prompted me to process another film from this batch tomorrow; perhaps there really is something wrong with this batch. I’ll report back faithfully. For the test, however, I won’t be using the aph, but will open a new bottle of Rodinal. We’ll see.

Hi Tilman,
What does the area next to the one in the picture on the left (i.e. on the 'dusty side') look like?
At first glance, all I can see is dust (in the 1.50
