The 35mm film format was developed and produced at an experimental scale in Thomas A. Edison’s laboratory by splitting 70mm roll film. Edison compiled his caveat for the double perforated cine film in the fall of 1889, describing it as a double perforated long band passing from one reel to another, driven by two sprocket wheels.

LAB-BOX is a multi-format tank that allows to develop film from start to end, in full day light, bypassing the need to load the rolls in the dark. Thanks to the two interchangeable modules and its multi-format reel, the tank can be used for both 135mm and 120mm. The 135 Module has a film slot where the 35mm cartridge is positioned and blocked. The film is then clipped and the lid is closed in order to rotate the outer knob and loading the film onto the reel.
