Rotational Tank System; Duo-Set 2502 - JOBO 3012 Manual

Rotational tank system 2500

The 2500 system tanks were developed
to meet the needs of professional
photographers. They are compatible with
all standard films from 35 mm to 4x5"
It is a system in which the tank size can
be adapted to match the quantity of film
to be processed, thus enabling optimum
use of chemicals.
A slide ring mechanism permits easy
and safe locking and unlocking of the
tanks and their lids. Solutions can be
poured in during rotation.
Various reel types are available for
processing 35 mm, 60 mm and sheet
films up to 4x5".

Duo-Set 2502

This reel is adjustable for 35 mm, 46 mm
and 120/220 films.No loader is needed;
the film is "walked" into the reel. Using
the Duo-Clip enables it to hold two rolls
of 120 film.
60 mm
35 mm
To load 35 mm film, cut the end square,
and trim the corners on the lead end of
the film. For 120/220 films, remove the
paper backing and fold over the tape to
make the film end more rigid. Again, trim
the corners on the lead end of the film.

Duo-Clip
Open the Duo-Clip and then push the
film into the opening on the outer layer of
the reel. Press your right index finger on
the film edge protruding through the
recessed section of the reel. Turn the
right half of the reel forward (clockwise)
until it stops to advance the film. Lift your
right index finger and repeat the same
procedure with the left half of the reel.
By advancing the film alternately with
the right and left halves of the reel, load
the full length of the film into the reel.
(Remove any cartridges or spools
attached to the end of the film.)
When loading two 120 rolls into the reel,
advance the first to the stop at the center
of the reel. Press down the Duo-Clip to
prevent the film from moving and then
load the second roll, in the same manner
as the first, until the trailing edge of the
film has gotten just into the outer layer of
the reel. The pin on the inside of the reel
prevents the inner layers of film from
touching each other.
