Alkaline fix for use with PMK and other processes
Ammonium thiosulfate (58-60%) 800ml
Sodium Sulfite (anhydrous) 60 g
Sodium Metaborate 5 g
Distilled water to make 1L
Mixing instructions: Add chemicals in specified sequence.
Dilution: 1+4
Notes: Fix for 3x clearing time. This formula is faster than older hypo-based fixers, but takes longer than an acid-based fixer.
shake up the concentrate to get the white stuff on the bottom all mixed up,
pour out 250ml of that into a 1000ml measuring cup,
add 750ml of distilled water, stir this up well,
then store this in a brown 1000ml glass bottle.
I use and re-use this to fix my 35mm and 120 film until it exhausts at about 20-30+ rolls later.
4-5 min for most films, 6-7 for Tmax/Delta films.
Agitate for 15->30 seconds of each minute.
