Chemicals for Minox Tri-X Film Development

The goal is to provide these chemical working-solutions:
 - DEVA 8 oz Diafine developer solution A
 - DEVB 8 oz Diafine developer solution B
 - HYPO 8 oz Kodafix
 - WASH 30 oz hypo-remover
 - AQUA 32 oz distilled water
 - FLOW 32 oz Photo-Flo

Supplies
 - Diafine Two-Part Compensating Film Developer
 - Kodak Professional Kodafix solution, a fast-acting hardening fixer
 - Ilford Universal Wash Aid Chemistry hypo-remover
 - Kodak Professional Photo-Flo 200 solution
 - two gallons of distilled water
 - 3 8oz glass bottles, 2 glass quart bottles, 3 plastic quart bottles
 - liquid measure cylinder (or ordinary kitchen measure)
 - eyedropper/syringe (plastic plunger type, 10 ml, look in baby aisle)
 - marker (MARKS-A-LOT FineMark PERMANENT MARKER)
Mixing Chemicals
Chemical measurement need not be perfectly exact, just good enough. Some of these chemicals are sensitive to light and temperature, so keep all chemicals in a cool and dark place. WARNING: Some of these chemicals are dangerous to health and can harm clothing. Never allow chemicals contact skin. Wear safety-glasses, gloves and apron. Keep away from children and do not allow confusion with food.
Observe warnings on chemical packages.
Important! Label each bottle and cap with the four-letter names.
DEVA: Put half a quart of distilled water into glass quart bottle. 
  Add the dry chemical contents of Diafine container A. 
  Cap, invert once to mix and repeat every several minutes
  until all chemicals have been dissolved in the water. 
  Add enough distilled water to make one quart. Cap and invert to mix.
DEVB: Put half a quart of distilled water into glass quart bottle. 
  Add the dry chemical contents of Diafine container B. 
  Cap, invert once to mix and repeat every several minutes
  until all chemicals have been dissolved in the water. 
  Add enough distilled water to make one quart. Cap and invert to mix.
HYPO: Put 6 oz of distilled water into 8 oz glass bottle. 
  Add 2 oz Kodafix to make 8 oz. Cap and invert to mix.
WASH: Put 24 oz of distilled water into plastic quart bottle. 
  Add 6 oz Wash Aid to make 30 oz. Cap and invert to mix.
FLOW: Put almost 32 oz of distilled water into plastic quart bottle. 
  Using syringe, add 3 ml of Photo-Flo.
  Cap and invert to mix.
AQUA: Fill plastic quart bottle with distilled water. Cap and store.

Finally:
  Fill the DEVA 8oz glass bottle from the storage-solution.
  Fill the DEVB 8oz glass bottle from the storage-solution.
Bottles
Size selection is critical only for HYPO, because fixer goes bad in air (smells like rotten eggs) and small bottles are needed for long shelf life. The Diafine developer chemicals are dry chemicals, the other chemicals are liquid. Dry chemicals are difficult (practically impossible) to sub-divide for small mixtures, so I use one-quart packages of Diafine and mix full quarts. The other chemicals are available in liquid form, so I mix single working-solution bottles of these chemical solutions as needed.

Now consider the bottle material: glass or plastic. Glass is best chemically but plastic can be squeezed to expel air (really only applicable to fixer, but I don't bother), and plastic is lighter and less likely to break. I use glass for all hard chemicals (DEVA, DEVB, and HYPO), so these go in 8 oz glass bottles, small mayonnaise jars. DEVA and DEVB storage-solutions go in 32 oz bottles, large glass instant-coffee jars. AQUA, FLOW and WASH go in plastic (PETE ) quart bottles.

For HYPO (marks at 6 oz and 8 oz) and WASH (marks at 24 oz and 30 oz) I mark measurement points on the bottles after pouring measured tap water so to never put chemicals into measuring device.

Important! Label each bottle and cap with the four-letter names.


Chemical Handling
Some of these chemicals are dangerous to skin and the fumes can be annoying. Also, a dust-free environment is essential. Close doors and windows. Shut off heating or air conditioning. Run an air filter but don't aim at work area. Shut off air filter while working with film and chemicals. Minimize air flow around work area. Never allow chemicals contact skin. Wear safety-glasses, gloves and apron. If you can smell the fumes, wear a mask, but none of these chemicals have dangerous fumes.
