The 5L FUJIFILM CN-16 Neg N1-MV Developer Replenisher (4-pack) is a single-part color film developer. It can be used for processing all types of color negative films compatible with Process C-41 in all processing equipment. CN-16 is made with the ingredients necessary to withstand the great chemical demand required for low film processing volume environments, and helps increase quality and productivity for such environments. The CN-16 is designed to replenish at a rate of 25 ml/roll of 135-24 film. It is intended for use in film processors that do not use cartridge chemicals and use a volume of replenisher per week equal to 15% of the developer processor tank volume. The developer comes in four 5L containers.
Changing to the CN-16 film developer is easy: Just mix it according to the directions, reset the replenishment rate and begin replenishing right over the top of your working tank solution. There's no need to dump your existing product.
