Perfect for C-41 Color Processing

I use this primarily for developing color negatives in 4x5. Temperature retention is excellent, and the agitation is smooth. The authentic JOBO build quality ensures that my chemistry doesn't leak even during vigorous inversion.

Solid construction, pricey but good

It is expensive, but you are paying for precision. The internal ribs guide the film perfectly. My only minor complaint is that the lid can be a bit stiff to twist off initially, but it loosens up with use.

Worth every penny

I was hesitant about the price compared to generic alternatives, but the quality difference is night and day. No leaks, no staining, and the plastic feels durable enough to last a lifetime. Essential for any serious darkroom worker.

Great tank, slight learning curve

Excellent product overall. It took me a couple of tries in total darkness to master loading the sheet film holder without bending the corners, but once I got it, results were fantastic. Just practice your loading technique before committing expensive film.

Reliable Darkroom Companion

I've been using JOBO tanks for decades, and this 2509N maintains the high standard. It's lightweight yet robust. The lid seals tightly, giving me confidence when processing irreplaceable shots.

The Gold Standard for Large Format

This tank is built like a tank should be. The fit and finish are impeccable, typical of German engineering. Loading the 4x5 sheets is intuitive once you get the hang of it, and the inversion method yields perfectly even development every time.

5 FAQ

Q: Is the plastic resistant to Ilford Ilfosol 3?

A: Yes, the high-impact ABS plastic used in genuine JOBO tanks is resistant to all standard black and white developers, fixers, and wetting agents, including Ilford Ilfosol 3.

Q: Can I use this tank with a JOBO rotary processor like the CPA-2?

A: Yes, the 2509N is fully compatible with JOBO rotary processors including the CPA-2, CPE-2, and ATL series, allowing for automated temperature control and agitation.

Q: How many sheets of 4x5 film can this tank hold at once?

A: The standard 2509N tank configuration holds one sheet of 4x5 film per holder. Additional holders can be purchased separately if you wish to process multiple sheets simultaneously in the same tank.

Q: Does this tank come with the spiral reels for 35mm or 120 film?

A: No, the 2509N is specifically designed for 4x5 sheet film and includes a dedicated sheet film holder. It does not include spiral reels for roll films.

Q: What is the minimum amount of chemistry required for one sheet of 4x5?

A: For inversion processing, we recommend a minimum of 300ml to ensure full coverage. For rotary processing, you can often reduce this to around 150-200ml depending on your specific machine's requirements.
