Can I use 425ml of solution with Jobo 2520 to develop 120 roll film ?

I need to develop film with Tmax Developer at dilution 1:4 and the minimum amount of developer is 85cc.

 

I will use the 2520 with Jobo CPP2.

 

Thanks a lot

It's twice as much developer than you need according to the tank instructions - here -.

 

Using too little developer would be a bigger mistake. Better too much than too little.

If I follow these instructions for Rotary Agitation, using Tmax developer at dilution 1:4 I can only use 54 ml of developer mixed with 216 ml of water ( = 270 ml of final solution ). Too little developer.

I've forgotten the details, but when I was using a motorized Jobo for processing I often used Rodinal 1:50 for T-max 100. I dumped the developer after half the processing time and poured in a fresh batch to finish.

- No. The tank will actually hold much more than 270ml or even 425ml of solution. 270ml is the minimum amount needed for rotary agitation. Any less and the film may not be fully covered. Using more is fine.

 

If you read the PDF instructions I linked to above, you'll see that the tank can hold 1500ml of solution.

Ok. I have it clear now.

 

Thanks.
