Film Capacity

The Adorama stainless steel developing tank accepts two 35mm reels or a single 120/220 reel. It is built for photographers who process black-and-white or colour film in a home or professional darkroom. The seamless spun-formed body resists the corrosive chemistry used in standard developers, stop baths and fixers. This tank suits anyone needing a durable, reusable vessel for small-batch processing.

Temperature Control Limits

Because the tank has no insulating layer, it reaches thermal equilibrium with a surrounding water jacket quickly. This behaviour lets you adjust development temperature by changing the bath temperature, but it also means the tank cannot hold a set temperature on its own. Users who rely on passive insulation to keep chemistry stable will need an external water bath or tempering system. Rapid cooling or heating steps are straightforward, while long standby periods require active management.

Reel Compatibility

The tank accommodates exactly two 35mm reels or one 120/220 reel per processing run. Photographers who regularly develop more than two 35mm rolls or multiple 120 rolls simultaneously will need additional tanks. The PVC snap lid seals the single opening for agitation and pouring. No other reel sizes or formats are supported by this design.

Questions about this item

Should I pick the two 35mm reel setup or the single 120/220 reel setup?

Choose the two-reel 35mm option if you shoot 35mm and want to develop two rolls at once; choose the single-reel 120/220 option if you shoot medium format.

How does the stainless steel body behave when I drop it into a water jacket for temperature control?

The spun-formed steel has no insulation, so it equalises rapidly with the surrounding water bath, letting you hit and hold precise development temperatures.

What does the PVC snap lid with seal cap actually prevent during processing?

It creates an airtight barrier that stops processing chemicals from leaking out and keeps contaminants from reaching the film inside.
