Does anyone have the formula for Agfa Neutol WA paper developer?
Does anyone have the formula for Agfa Neutol WA paper developer?
It's not published, and it seemed to me to be a unique formula among of the shelf developers.
Ansco 135 (ardol) is a published formula with a lot of similar characteristics that might be worth looking at. But it's not the same thing.
I don't know the formula for Neutol WA, but results from my Rapid Universal developer are practically indistinguishable. If you're interested in the formula, let me know.

I'd be interested. I have a friend who really liked neutol.
has agfa announced the end of processing chemicals...?

Jack-
I don't have a formula but the ingredients as I recall were Potassium Sulfite, Hydroquinone, Potassium Carbonate and EDTA Sodium Salt. The Ansco 135 that Paul mentions is a Metol formula, considered a warm tone developer. Depending on the paper that you are using it might be worth a try. Good question, Tim.
Hi Paul.
Here's the formula:
DRU
distilled water 750ml
Sodium sulfite 36g
Hydroquinone 3.6g
Sodium carbonate 20g
Borax 10g
Phenidone .5g
Sodium ascorbate 4.5g
BZT 1% 10ml
distilled water to 1 liter
For warmer tones, substitute 1g KBR for the BZT.
Jay
just curious ... why both sodium carbonate and borax?

First, an addendum to Merg's list taken from Agfa's Neutol WA MSDS. The EDTA is Tetrasodium salt, and other ingredients include Phenidone and Potassium bromide.
Given that Agfa rates shelf life of the Neutol WA concentrate at 2 years, and considering recurring rumors that conventional photo products from this manufacturer will soon disappear, I'm thinking about purchasing four 1250ml containers of Neutol WA and decanting it into five 1 liter glass bottles. I hope that the developer will keep somewhat longer and tide me over until a permanent darkroom (with facilities better suited to mixing powdered chemicals) and a long-awaited supply of amidol become available.
This leads to a question for those using Neutol WA: what is the batch number on the label of your most recently purchased stock? I'd like to store up from the freshest production available, so thanks in advance for your help.
