Paterson Film Developing Tank – 2x35mm or 1×120 + 2 Reels

Trusted by analog photographers worldwide, the Paterson Super System 4 tank is a staple in home darkrooms and is even featured in the book Analoge Fotografie. With a patented self-sealing rubber lid that eliminates drips and spills, this tank makes developing film a smooth and mess-free experience.

This model fits two 35mm rolls or one 120 medium format roll, using high-quality auto-loading reels with ball bearings for easy loading—even in complete darkness. The ergonomic design makes inversion agitation easy and secure, and the tank sits comfortably in the hand.

The included reels are compatible with AP systems, and vice versa—so you can mix and match equipment if needed. The Paterson tank requires slightly more chemistry than a JOBO 1520, but in exchange, offers easier handling and reliability.
