DEEP TANKS

Contain a large volume, acting as a reservoir of processing solution which can be replenished to keep it in more or less constant activity for a long period of time. Originally supplied by Kodak as '3 Gallon' (13.5 litres), they were upgraded to 15 litres by ProCo when they took over production.

Normally supplied with a cover lid, and a floating lid (to exclude air) is required for use with developers.

See also stainless steel baskets and hangers.

A separate wash tank is also available.

COMBI PLAN 5x4 DEVELOPING TANK

There aren't many alternatives when it comes to processing small quantities of sheet film; this is one of the more elegant. A clear plastic frame with slots locates the films. There are slots for 6 sheets, although the user may find less problems with agitation if only 4 are processed at a time. A close fitting soft rubber lid allows inversion agitation, and a drainage outlet at the base allows daylight use.
