    Re: agfa neutol wa formula

    Just look at ID20 (MQ)/ID-62(PQ) and the warm tone variant ID-78.

    Replace the Phenidone with 3 grams of Metol, you may need to add a gram or two more of Bromide. That is around 10x

    Use either formula Neutol WA or ID-78 they give virtually identical results, but as Metol is a fraction colder working you may need to add an extra gram of Potassium Bromide.

    Thanks Ian for the quick reply. I will try that suggestion and see what happens.

    EDTA Na4 10g
    Potassium Sulphite 225 g
    Hydroquinone 45 g
    Phenidone 1.5 g
    Potassium Carbonate 45 g
    Potassium Hydroxide 15 g
    Potassium Bromide 10 g
    Water to 1 litre

    Use 1+9 (1+7 - 1+14)

    Like Ilford ID-78 it has a good shelf life, both give very similar tones.

    Greetings to all .
    This formula looks really great.
    I have a simple inquiry, please.
    Regarding Phenidone, it is actually not available in Egypt, and I had heard here that I can make up for it by using Metol 10 times.
    Let me just confirm,
    Does this mean that the compensation ratio is as follows:
    1.5 x 10 = 15 grams

    can't answer that question but I make a lovely warm tone developer with no exotic ingredients
    Ansco D55
    water 750ml@ 125 degrees F
    metol 2.5 grams
    sodium sulfite 37.5 anhydrous
    hydroquinone 10 grams
    pott bromide 12grams
    sodium carbonate anhydrous 37.5
    water to make 1L
    use 1:2
    I've been using this for years and while I really like Neutol WA it has gotten expensive to buy
    try this formula you will like it!!

    God bless you, my dear teacher.
    You are a very nice man
    Actually, I remembered sharing now.
    I have already prepared (Neutol WA) according to the attached formula:
    EDTA Na4 10g
    Potassium Sulfite 225 g
    Hydroquinone 45 g
    Phenidone 1.5 g
    Potassium Carbonate 45 g
    Potassium Hydroxide 15 g
    Potassium Bromide 10 g
    Water to 1 liter

    But I put the sodium sulfite with a mixture of potassium sulfite and this bothered me a lot and it was difficult to melt but it eventually melted after a lot of effort, and after adding five grams of potassium hydroxide.
    I will prepare your description according to your advice next week.
    But I have a question, regarding the formula ((Neutol WA)) I do not know what is the appropriate temperature for developing a negative Negative and what is the necessary processing time and the necessary dilution.
    Greetings to you, dear sir.

    Neutol WA Containing (Na4)
    EDTA Na4 10g
    Potassium Sulfite 225 g ( 225 g sod. sulfie)
    Hydroquinone 45 g
    Phenidone 1.5 g ((15 g Metol ))
    Potassium Carbonate 45 g
    Potassium Hydroxide 15 g
    Potassium Bromide 10 g
    Anti Fog .................1 g
    Water to 1 liter

    Is this format suitable for film?
    How long, how often, and how much is the dilution rate according to the published German formula?

    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.
    I'm preparing chemistry from scratch.
    I never buy any pre-made developers ,,,
    - Yes, phendion is not available, but I do add metol (10 times) and a little (CD2). Things are fine.
    Storage in a glass container is very important and effective.

    Allow me a final inquiry
    Have you already prepared that formula?
    The formula from the German book (containing EDTA)
    But I want to use it to treat negative films, not paper.
    Do you know what the dilution rate would be if you wanted to develop films?
    God bless you

    Mohmad, this is a paper developer. Why do you want to use it for film?
