Paterson Super System 4 Multi-Reel 8 Developing Tank

Yes, you could fit two MOD54s in the Multi Reel 8 tank.

No, the CatLABS CL81: an 8X10 Sheet Film Processing Reel is made specific for the Jobo MultiTank 5. Not the Paterson Super System 4 Multi-Reel 8 Developing Tank. This is the link to the Jobo 2550 Multi Tank 5 (640mL), https://bhpho.to/3plCZu0 .

Unfortunately no but you can use this Jobo instead: https://bhpho.to/3d6s1p9

it comes with centre column

No it does not.I use mine for Semi Stand development. So a minimal amount of inversions.You might want to ask someone who processes the way you would want to use it.Hope this helps.

Yes, it does. You get the top, funnel, tube, and something you can put at the top of the funnel to agitate as well. The reels are not included. Sorry for the delayed response. I'm just catching up on my emails.

The standard rule of thumb is 10 oz (300 ml) for each 35 mm plastic reel, or 2400 ml or 80 oz. It's a good idea to add a little more chemistry than that. Even if you have 7 rolls of film, you must add the 8th reel and the chemistry to reflect 8 reels to make sure no light leaks in the gap.Or, you may use 5 rolls of 120 film to fill this tank. Each reel requires 500 ml (17 oz), for 5 rolls 2.5 liters (85 oz). Any other combination of 120 and 35: before loading, stack your reels and make sure the funnel locks in place. If too high, the funnel won't lock in place. Don't do it. You won't have a tight seal and you will leak light and fog your film, or worse.
