Ars-Imago Lab-Box Module 120

If you already own the Ars-Imago Lab-Box daylight developing tank and want to process medium format film, this 120 Module is the essential add-on. It allows you to develop 120 roll film in full daylight without the need for a darkroom or changing bag, making it an easy step-up for anyone expanding their home processing workflow.

Why We Like It

The Lab-Box system is a clever bit of kit for anyone who wants to develop film without setting up a full darkroom. This 120 Module lets you take advantage of the same straightforward daylight-loading process, but with the larger negative size of medium format. We recommend it for students, home processors, or photographers who shoot both 35mm and 120 film and want to use one tank for both. Just be aware that some PET-based films can be tricky to load, so it’s best to stick with compatible emulsions for a smooth experience.

Customer Reviews (4.8 / 5 · 5 reviews)

Avery ★★★★★

Switching from my previous setup was a breeze — the module clicks right into the existing Lab-Box with no extra tools needed. The film reel loads smoothly and the whole unit stays light-tight, so I can develop 120 film confidently under normal room light.

Scarlett ★★★★★

Finally, I can develop my medium format rolls in the same daylight tank without fumbling in a dark bag. The module snaps in securely and the spiral loads smoothly even with slightly curled film. It's made my home processing workflow so much more efficient.

Elizabeth U. ★★★★★

Loading the film onto the spool was surprisingly smooth thanks to the self-centering mechanism, and the light trap keeps everything dark even in a bright room. I’ve been able to develop two 120 rolls back-to-back without any leaks or issues. Definitely worth it for anyone already using this tank sys
