ECP process Replenish guide:

ALL chemistries need to be replenished after each use. Replenishment rates are calculated by the quantity of film processed.


ECP REPLENISHING RATES FOR 16MM FILM:

ECP 1 = Developer             14,7 ml per meter;      345 ml for a 30,5 meter 16mm roll 
ECP 2 = Stop Bath             11,3 ml per meter;      350 ml for a 30,5 meter 16mm roll
ECP 3 = Bleach                3,3 ml per meter;      100 ml for a 30,5 meter 16mm roll
ECP 4 = Fixer                 9,8 ml per meter;      300 ml for a 30,5 meter 16mm roll


Steps for replenishing:

1. Take the replenisher ECP 1R (developer) from the fridge.The other chemistry is in the yellow crate. 

2. Pour the required amount of replenisher into a 2-litre measuring cup.
3. Pour the used chemistry into the 2-litre measuring cup until it completes exactly 2 litres.

4. Put the leftover chemistry into the respective recycle chemistry container. 
5. Label the replenishment date on each bottle.

6. Make sure you fill in this form :)

Note: Small tanks can fit 8-10 meters of film. Medium tanks fit 15 meters of film. Large tanks fit 30 meters of film.

Note: If you don’t feel comfortable replenishing chemistry by yourself, please come to the lab when Esther is available.
