Paterson Super System 4 Developing Tank (3-Reel, AGO Modified)

Overview

In the box: the Paterson tank body with its watertight EVA cap, the AGO-modified funnel already drilled with the three holes chemistry pours through, plus the lid and agitation rod — no drilling and no template needed. The 3-, 5- and 8-reel tanks ship without reels, so add Paterson Auto-Load reels (adjustable for 35mm, 126, 127, 120 and 220), a Vintage Visual REEL 110 for 110 film, or a sheet-film REEL as needed. This size takes up to three roll-film reels, or one 4×5 or 9×12cm REEL holding up to four sheets. On the AGO the minimum chemistry volume is 450 ml for roll film and 350 ml with a 4×5 or 9×12cm REEL, and with the 4×5 reel the listed volume has to be followed accurately. The AGO can agitate it rotary (horizontal) or vertically with the stick, but time compensation only runs in rotary mode — in vertical mode the temperature probe does not sit in the liquid, so compensation is switched off. Rotary agitation uses up to 60% less chemistry than traditional vertical or inversion agitation methods. The 5×7 and Paper 5 REELs need a Paterson 5-reel tank or larger, so step up a size if 5×7, 8×10 or RA-4 prints are on your list. Without the AGO it behaves as an ordinary Paterson tank for hand inversion development.
