Paterson Film Developing Tank Roller

This roller is designed to work with a wide range of standard developing tanks, including the Jobo 1505, 1510, 1520, 2520, 2509, as well as Osiris F1, AP, and JC tanks. It accommodates tanks with lengths between 10 cm and 16 cm.

Bidirectional rotation ensures that chemicals are distributed evenly across the film surface throughout the entire process. By rotating forward for 8 seconds, pausing for 1 second, and then reversing for 8 seconds, it significantly reduces the risk of uneven development or streaking often caused by manual agitation.

Yes, the unit features fully adjustable speed and timing controls. You can set speeds between 20 and 280 RPM and program timers ranging from 1 second up to 30 minutes and 59 seconds, allowing you to tailor the agitation to specific film and developer combinations.

Absolutely. The unit is built with anti-corrosive metal, specifically designed to withstand the harsh, wet conditions of a darkroom and resist degradation from chemical exposure over time.

Yes, it features a built-in buzzer alert that triggers upon process completion. This allows you to step away from the tank while it is running and ensures you never miss the exact moment your development cycle ends.

Yes, the roller includes four programmable processing presets. This allows you to store your most frequently used speed and timing configurations for quick, repeatable access during your workflow.
