Solid upgrade from standard tanks

Works well for both 35mm and 120 formats. The only minor issue is that cleaning the bellows folds requires a bit more attention than a standard tank, but it's worth it.

No more air gaps

Finally, a tank that eliminates headspace completely. The solution stays fresh between sessions. Highly recommended for anyone developing black and white film regularly.

Essential for the eco-conscious developer

I love that this reduces oxidation. My D-76 lasts much longer now. The build quality feels robust and the markings on the side are clear and easy to read in low light.

Excellent engineering

The extendable design is brilliant. It adapts perfectly to the volume of liquid needed. No spills, no oxidation, and consistent results every time.

Great concept, slightly stiff at first

The bellows mechanism was a bit hard to push down initially, but after a few uses it loosened up nicely. It's a game changer for extending the life of expensive developers.

Perfect for minimizing chemical waste

The compression feature works exactly as advertised. I can develop a single roll of 35mm film using significantly less developer than with my old tank. The seal is tight and no leaks occurred during agitation.

5 FAQ

Q: Is the lid interchangeable with standard Paterson tanks?

A: No, the lid features a specialized sealing mechanism required for the compression function and is not compatible with standard Paterson or Jobo tank lids.

Q: How do I clean the inside of the compression bellows?

A: We recommend rinsing immediately after use with warm water. For deep cleaning, fill the tank with a mild cleaning solution, extend and compress the bellows several times, then rinse thoroughly. Avoid abrasive brushes.

Q: What is the minimum volume of developer required for one 35mm roll?

A: Thanks to the compression feature, you can effectively develop one 35mm roll with as little as 350ml of solution, though 400ml is recommended for easier agitation.

Q: Does this come with reels included?

A: This package includes the tank and bottle only. Reels are sold separately to allow you to choose your preferred brand (stainless steel or plastic) compatible with the tank diameter.

Q: Can this tank be used with C-41 color processing chemicals?

A: While the material is chemically resistant, this tank is specifically designed for B&W processes where temperature precision and agitation styles differ. We recommend using dedicated color tanks for C-41 to ensure optimal temperature stability.
