Jobo 1530 フィルム現像タンク延長モジュール

This extension module fits perfectly onto my existing tank and lets me develop four rolls of 120 film at once. The 330ml minimum for rotary processing is a real chemistry saver.

I was worried about using less chemistry with my rotary processor, but this module lets me use just 330ml for three rolls of 35mm film—saves money and works perfectly.

Finally I can process four rolls of 120 film in one go—the extension module clicked right onto my existing 1500 tank with zero leaks. Used the 725ml minimum for rotary and got perfectly even development across all four rolls.
