Suitable for processing up to two rolls of 35mm or 120, the Jobo 1520 UniTank is a plastic daylight tank, which includes one multi-format 1501 reel. The tank is suitable for inversion/manual processing, includes an inversion-type lid, and requires 485mL of chemistry for development. Alternatively, it can also be used in conjunction with an optional processing machine for rotation-type development, where it requires 240mL of chemistry and an optional cog-style lid. It features a modular design and is compatible with the optional 1530 module to increase its capacity to accept additional reels.
