Measuring C41 developer components in small volumes using weight?
I have been pondering what is the simplest method to measure small volumes of the Kodak Flexicolor LU LORR C41 developer components to do oneshot processing in my rotary processor. (For those times when I don't have enough rolls made up to justify mixing up the whole 5L+ batch.)
If I want to measure out 2L of developer tank solution I come up with numbers like this:
Starting Water 
1220.80 
Developer LU LORR Part A 
122.08 
Developer LU LORR Part B 
34.18 
Developer LU LORR Part C 
17.09 


Add Water to Make: 
1940.00 
(Should be…) 
545.85 


Add Starter: 
60.00 


Total tank solution: 
2000.00 
To measure 122.08, 34.18, 17.09 mL seems tricky to do even with a pipettte. Would it not be easier to use a digital scale, say one that was accurate to .01g precision with a 500g capacity? Those sell for cheap. To be really precise I would need to know the specific gravity of each part, which I am not sure Kodak publishes. But I could maybe assume 1.034 which is what they have as a published number for the overall developer.
I am curious if this is a good idea or not?
Cheers,
Justin
