Product Overview

🎯 Why Choose the Paterson PTP 115 Film Developing Tank?

There are many film tanks on the market, but the Paterson PTP 115 Universal Film Developing Tank stands out for its user-friendliness, smart design, and professional-level results. Here’s what makes it a top choice for photographers:

1. Universal Reel System

The tank includes two Paterson Auto Load Reels, which are adjustable to fit both 35mm and 120 film formats. These reels are well-known for their simple loading process, eliminating the frustration that often comes with hand-spooling film.

2. Daylight Processing Convenience

Once you’ve loaded your film in the dark (using a darkroom or changing bag), the rest of the developing process can be done in daylight — thanks to the light-tight lid design of the Paterson PTP 115. This makes the tank ideal for home use or traveling photographers.

3. Even Development with Efficient Agitation

The tank’s large diameter and wide opening allow for smooth chemical flow and uniform agitation, ensuring every frame of your roll is developed evenly. The central column ensures reels stay in position, and the agitator rod allows for controlled mixing of chemistry without opening the lid.

4. Durable and Reusable

Made from tough, chemical-resistant plastic, the Paterson PTP 115 is built to last for hundreds of uses. It’s lightweight, compact, and easy to clean — perfect for personal or studio darkrooms.

🧪 Compatible with All Major Developing Chemicals

Whether you’re using Kodak, Ilford, Adox, Cinestill, Foma, or other brands, the Paterson PTP 115 Tank is fully compatible with all standard B&W and C-41 developing chemicals. You can process negative and slide film alike with proper chemistry and temperature control.
