Reuse

Checked 21 October 2026

Acufine says Acufine may be used for more than one film. It can also be replenished.

Longer time for reuse: Four rolls at the normal time, then +2 % for each additional roll, up to 16 rolls per quart.

Capacity, as the maker states it: Without replenishment: four rolls at normal times, then +2 % for each additional roll; no more than 16 rolls per quart.

Replenishment can be continued until a volume equal to the volume of the original developer has been added. Without replenishment, four rolls of film may be developed at normal times. Increase the developing times by 2% for each additional roll. Develop no more than 16 rolls per quart in this manner.
