    Hi,
    Anyone using the BTZS 8x10 tube. I want to know the minimum volume of working dilution developer use for each tube.
    I use the Pyrocat-HD 2:2:100, 60cc for 4x5 so I wonder how much developer should I use for the 8x10.

    Thanks,
    TN

    The volume of the cap.

    I use the 4x5 tubes, but not the 8x10. But roughly speaking, I would guess 4 x 60ml = 240 ml. Is that about the volume of the cap?

    The cap will hold 255 ml if filled to the lower edge of the bevel. I use 240 ml as Jerold suggests.

    Thanks, everybody. I think the 250ml would be great since I always mix the developer at 500 or 1000ml.
