Looking for an inexpensive source for the above.
Freestyle doesn't list anything.
Thanks, I saw that at B+H, but the cost is over $30 with shipping.
I learned that Freestyle has it listed under another name: Moersch Restrainer Neutral, less expensive than B+H.
I believe this is just Benzotriazole (BZT). Buy some bulk from the formulary and mix it up.
Yep. That's the best way...EC
Benzotriazole dissolves sparingly in water, but better in an alkaline solution. I read somewhere that Orthazite was just benzotriazole in a mildly alkaline solution which I think was just sodium sulphite. The sodium sulphite would have a negligible effect on any developer.
How much do you want Karl, I could put some Benzotriazole (dry) in a film cannister, postage would be about $3 to Canada/US.
I, like Ian, also have a lifetime plus supply of BZT needles ( 96 or so of original 100g on hand presently I think). If I am more local I would be pleased to mail you a few grams. PM me if you are interested.
I think you're a lot more local A little Benzotriazole goes a very long way.
I have a pound of it and use it at 1% solution. I'm making provisions to pass it in my will ..EC
I use benzotriazole all the time. It doesn't take much. Maybe a dollar a year for a benz junkie like me.
I use it in my 130, replacing the bromide...a great developer
BZT dissolves easily in alcohol. I mix a 1% solution dissolving the chemical in 200ml rubbing alcohol, add water to make a liter. Easy. Quick.
Once I used a liter of alcohol to dissolve it, not knowing any better. Almost fumed me out of the darkroom putting a mere ounce in a tray of developer!
