Diafine Dilemma

I have been trying to get Diafine 1L pack (the US quart version) from all my usual suppliers in the UK and mainland Europe to no avail. It appears that BKA in Illinois have been taken over by OmegaSatter - they are now known as OmegaBrandess!

 

Supplies of the the 1L pack are low to non-existent in Europe and the dollar-sterling/euro strength is going to push the cost up considerably plus one supplier had heard that the new company are putting the price up.

 

It would be a real shame to see Diafine price itself off my darkroom shelf.

Easy enough to make your own Diafine:

Part A: 750ml Water

35gm Sodium Sulfite (anhy)

6gm Hydroquinone

0.2gm Phenidone

6gm Sodium Bisulfite

Water to make 1 litre

 

Part B: 750 ml Water

65 gm Sodium Sulfite

20 gm Sodium Metaborate (or 20 gm Borax to mimic a "D-76 look")

Water to make 1 litre

 

Ingredients last forever, and can be the basis for many developers.

Well Diafine is a proprietary developer and the MSDS sheets only show one ingredient for each bath, the rest appears to be a trade secret.

 

I have mixed and used most of the 'Diafine-like' developers, including the one you posted - some good some mediocre. Plenty of options in The Film Developing Cookbook (Anchell & Troop) and Patrick Dignan's Classic B&W Formulas.

 

Just have to wait and see how the extra costs impact on whether European suppliers will continue to stock it.

Thanks guys but buying from Europe the shipping bumps the price up too!!

 

I don't want to make a gallon yet as we are packing up the house for moving.
