I dry film after development with my Tank2DryTM
device for dust-free film drying.
Look at the cotton in the nozzle; replace if it looks dirty.
Power-up the air-pump.
Insert nozzle into the top of the Minox Tank.
Park the assembly in a clean, dry location.
Wait for several hours until dry.
Store film uncut, emulsion on inside and put into clean large bottle cap,
write date on cap, several in a zip-bag.
The developer and fixer chemicals are used over and over.
All other chemicals are dumped after use.
The Diafine developer solutions almost never go bad chemically.
However, the solutions do get colored from dye in the film
and some DEVA is absorbed into the film emulsion.
If DEVA is less than half full, replace both DEVA and DEVB.
Or, dump some of DEVB to equal volume of DEVA,
then top-off each from storage-solutions.
If HYPO smells bad or becomes too weak, replace.
Replace or refill AQUA, FLOW and WASH as needed.
Dye in the film is washed out by the liquids.
The dye can stain a sink, so I dump liquids into a tub.
If connected to a septic tank, take to a household hazardous waste collection facility.
If connected to a sewer, everything can go down the drain
because we're dealing with a very small amount of chemicals.
Obey local laws.
Keep your equipment clean or suffer mysterious development problems.
Minox tank: shell, spiral, lid
Minox cassette: body, caps, spool
remove caps (squeeze body at marks and gently lift cap)
remove spool, separate from tape
discard film fragment and tape
bottles, emptied or exhausted
eyedropper, measurement cylinder, etc.
While the Minox film cassette is inside the Minox tank,
it is submerged in the several chemical solutions.
The Minox cassette has felt pads where the film enters and exits.
These felt pads need to be cleaned if you're going to reload with new film.
Take care to not destroy the felt pads.
Rinse equipment under warm tap water.
Fill sink with detergent water as you would for washing dishes.
Wash as you would dishes, then rinse equipment and sink.
Fill sink with warm tap water and add one ounce from FLOW bottle.
Immerse equipment, let soak for one minute.
Remove equipment, one at a time, shake to drain.
Place equipment in a dust-free location.
Bottles and the Minox tank get an additional internal rinse with
two ounces AQUA which can be used to rinse several bottles.
