Reuse
Checked 21 October 2026
SPUR says SPUR Dokuspeed SL-N may be used for more than one film.
Longer time for reuse: It is not necessary to extend the time if the films are developed one after the other, within the shelf life of the working solution; two films per 500 or 600 ml.
Capacity, as the maker states it: 250 or 300 ml of working solution develops one 135 film; 500 or 600 ml develops two 135 or two 120 films.
Capacity of the working solution: 250ml or 300ml working solution (depending on tank size) are enough to develop one 135-film. With 500ml or 600ml two 135 or two 120-films can be developed. ... It is not necessary to extend the time if the films are developed one after the other. The second development should be done within the shelf life of the working solution. ...
