The Paterson Multi-Unit 1 Tank (System 4) is a modern, user-friendly film developing tank designed for 35mm and 120/220 roll film. Part of Paterson’s highly regarded System 4 line, this tank offers fast filling and pouring, tight light seals, and smooth reel operation—ideal for beginners and seasoned darkroom techs alike. This Multi-Unit 1 model holds up to two 35mm reels or one 120 reel (reels not included), making it perfect for photographers who shoot regularly but don’t need a massive tank. The wide lid and large funnel system make chemical changes quick and clean, while the translucent tank walls help visualize agitation without opening.
