The Jobo 12 Reel Tank No.2513 is part of the Jobo 2500 series tanks. These tanks are modular, meaning that you can add an extension piece to one of the base tanks to develop higher quantities of film.
This tank holds up to 170ml of liquid. 1 roll of 35mm can be loaded per reel
All 2500 series tanks come with either a cog gear or magnet attached (this tank has a cog gear). The reason is that these tanks are too large for inversion (hand) processing and as such should be used with a Jobo processor.
Note: reels are not included, but are available separately.
