TF-2 Alkaline black and white fixer

tf-2 Alkaline fixer

Since I tried the formula #134 from classic “The Darkroom Cookbook” by Steve Anchell, the TF-2 Alkaline Fixer, didn’t need to buy ready made commercial fixer again.

Here is the Formula I use  (by Bill Troop):

Distilled water (~40˚C) 750,00 ml
Sodium thiosulfate (pentahydrate) 250,0 g
Sodium sulfite 15,0 g
Sodium Metaborate* 10,0 g
Water to make 1.0  l
*Sodium Metaborate can be hard to find depending on where you live, but you can substitute it with 7g of Borax + 1,5g of Sodium Hydroxide (Caustic soda)

The process is extremely easy:

  • Start by adding the sodium thiosulfate to the water and stir until dissolved.
  • Add the sodium sulfite and the metaborate and stir well until everything is dissolved.
  • Add distilled water to make 1 liter and the fixer is ready to use.

Keep in mind is not ideal for new tabular grain films as Ilford Delta or Kodak T-MAX, it takes a long time to fix, but for classic films as FP4 or HP5 works as a charm.

With one liter you can fix around 20 rolls of film, it’s odorless, and lasts for about 2 months. Highly recommended!
