Reuse

Checked 21 October 2026

The maker’s sheet doesn’t say whether it can be reused.

Capacity, as the maker states it: One package (1 litre of working solution): 12 films of 135-36 or 120.

Preparation of working solution: Dissolve the content of the smaller bag and then of the bigger bag in water (20 - 30 °C) and after a complete dissolution fill up with water to the final volume of 1 litre. ... Developing capacity: One package is sufficient to develop 12 perforated films (135-36) or rollfilms (120)...
