Jim:
I'm assuming your using D-19 developer, which is the standard for Tech Pan.
As far as dividing the D-19 gallon pack of dry chemicals is concerned, there 
is some disagreement. I prefer to mix the whole gallon, as per instructions, 
and then divide the gallon into two 1/2 gallon or 4 guart containers. It's 
best to use dark glass or plastic containers and fill them all the way up, 
leaving no air space. Keep them in a dark, cool place and just use them one 
at a time.

The Tech Pan-D-19 process is a standard B/W process; ie. developer, stop, 
fix, wash, dry. You can use a fixer eliminator between fix and wash, which 
shortens the wash time. With Tech Pan, some people use water for the 
stop-bath instead of the usual acetic acid stop bath, they say it prevents 
pin holes, but I've never had the problem.

How much chemistry you use will depend on the size of the processing tank.
Single 35mm reel tanks take less than larger ones.

Once the film has been in the fixer several minutes, it is safe to open the 
tank.
