Premier 2 Gallon Floating Lid film camera

Tank Accessory for Oxidation Prevention

The Premier 2 Gallon Floating Lid is a specialised accessory designed to fit a matching storage tank. It serves photographers and darkroom technicians who need to protect liquid chemistry from air exposure during idle periods. By limiting oxygen contact, the lid helps maintain developer and fixer potency between printing sessions. It is not suited for tanks of other capacities or for dry chemical storage.

Integration With Existing Tank Systems

The lid rests directly on the liquid surface inside a compatible two-gallon tank, requiring no tools, clamps or modifications to the vessel. Its floating design self-levels as the fluid volume drops, preserving a consistent barrier without manual adjustment. This frees the operator from cutting custom covers or relying on loose-fitting caps that allow evaporation. Buyers without the matching Premier tank cannot use this lid effectively.

Passive Operation With No Power Draw

The accessory operates passively, drawing no electricity and producing no audible noise during use. Because it contains no moving parts, fans or heaters, it adds zero thermal load to the darkroom environment. Its sole function is physical separation of the chemistry from the atmosphere, so long-term reliability depends only on material durability. Users seeking automated nitrogen blanketing or temperature control will need separate equipment.
