MOERSCH ECO Film Developer 750ml (1xA+1xB 250ml each) with dosing pipettes and bottle adapter

Properties: ecologically safe, free of hazardous substances, high contour sharpness, fine grain up to 200 ASA, accentuated grain at higher sensitivities economical, two-part concentrate for preparing a one-time developer Alternatively, can also be used as a positive developer at dilutions between 1+2+20 to 1+1+25

Shelf life of the concentrates: Guaranteed minimum shelf life of solution A 2 years, solution B has an unlimited shelf life.

The developer is supplied as a two-part concentrate. Part A is the developer concentrate, part B is the activator. For most films, the developer solution is prepared in a ratio of 2+1+50 with (demineralised) water. For deviations, please refer to the data sheet. The working solution can be kept for a few days, but I recommend to prepare only as much solution as can be used immediately. For exact dosing of small quantities, dosing pipettes are enclosed. The pipette adapter is pressed into the neck of the bottle, with the pipette in place, the bottle is turned and the required amount is drawn off. To avoid contamination of the solutions by mixing up the pipettes, they can remain attached. This type of closure is as tight as a lid. To withdraw larger quantities when measuring in a bore, only the pipettes are removed, the adapters should remain on. The recommended developer temperature is 20°C. The development times are then long enough to carry out shortened N-developments under reproducible conditions. However, to avoid calculations in case of deviating temperatures, times for temperatures between 19°C and 22°C are also given in the data sheet.

The information on film speed and development times cannot replace individual calibration, but is sufficiently accurate for initial trials as a starting recommendation. For N- and N+ development, the known laws apply (approx. -20% and +20-25%). For N+1, however, instead of extending the development time, the N time can be maintained by increasing the developer temperature by about 2°C.

Films that do not appear in the data sheet have either not been tested, or have been judged unsuitable for this developer after testing, or the deviation between individual batches is not tolerable. Images copy: http://www.moersch-photochemie.de/content/galerie/...
