Processing power
1 liter of each of solution enables one to process 1 square meter of the Silver Halide photomaterial (VRP-M, PFG-01, PFG-03M, PFG-03C, GEO-03).
Storage
The developer solution remains developing properties while stored for three days. Bleaching solution can be stored for about one week.
Processing even one plate in the developing and bleaching solutions noticeably reduce their lifetime to 24-48 hours.
All solutions should be stored in the closed dark glass or non-active dark plastic bottles. You can store them in a room temperature, but it is better to store them in the refrigerator at +5 degrees Celsius.
Work with chemicals
It is important to follow good laboratory practice while processing the photomaterials. The chemicals included in Geola’s set are not poisonous, however, please wipe up any spillage as soon as it occurs and use the polythene gloves. Download safety instructions here.
