The Jobo film developing tanks from the modular 2500 tank system are made of a high-quality, chemical-resistant plastic and are suitable for the development of 35mm film, roll film and sheet film, depending on the model. The 2500-series developing tanks are aimed at (semi-)professional use and are mainly focused on automated rotation development with a Jobo Film Processor. Nevertheless, the tanks can also be used for manual inversion development. This 2520?developing?tank is therefore supplied as standard with the red tank lid.
The Jobo 2520 Multi Tank 2 film developing tank is the most popular development tank of the 2500 series as it is one of the best solutions on the market for developing 4×5″?sheet film. Of course, the tank can also develop 35mm film and 120 roll film.
The Multi Tank 2 developing tank is compatible with one Jobo 2509N reel for sheet film development. This reel can hold up to 6 sheet films of size 4×5 inch / 6x9cm / 9x12cm. The reel is made of durable materials for long term use. The design of the reel has been further refined over the years to ensure optimal circulation of photochemistry and an even and consistent development of the sheet film. The reel can be loaded easily by hand or with the optional 2508K Jobo Sheet Film Loader for fast and scratch-free loading of the film into the reel. For rotation development with a Jobo Processor, the use of the supplied plastic guides is recommended for the most qualitative development. The 2509N reel is available separately.
The Multi Tank 2 is also compatible with the adjustable 2502 reel for the development of one 35mm film or two 120 roll films. The 2520 tank can hold up to two 2502 reels making it possible to develop two 35mm films at the same time. The tank can also develop two 120 roll films at the same time using the integrated clip in the film reel. Each 2502 reel?is equipped with a red clip which makes it possible to load two roll films on one reel without the risk of overlap. This possibility allows the 2520 Multi Tank 2 to develop two roll films at the same time, despite the fact that the tank can only hold one 2502 reel with an adjusted size for roll film. If the clip is not used, the tank can develop one roll film.?This 2502 reel is not included and is available separately.
For rotation development with a compatible Jobo processor, the tank only needs 270ml of photochemistry to develop 35mm film, 120 roll film or?sheet film and is one of the most economical solutions to develop film regardless of the format. In this case the tank must be equipped with a cog (#1505) to attach it to the processor lift or a magnetic base (#1504) if the processor is not equipped with a lift. Both accessories are not included and are available separately.
