What it is

A tall Paterson Super System 4 tank: three 35 mm films or two 120 in one daylight processing run. The large rubber lid seals the tank, so it barely drips when inverted. Reels are not included.

What it fits

You need three reels for 35 mm or two for 120. Paterson and AP reels both fit. The adjustable Paterson reel for 35 mm and 120 is available from me separately.

One practical note

Press the lid home all the way round until it seats — then the tank can be inverted without leaks. Load the reels only when dry.
