Ilford 2000RT paper developer and replenisher 5l

Ilford 2000RT paper developer and regenerator 5 l The 2000RT by Ilford is the ideal RC paper developer for throughput developing machines. The developer and fixer bath concentrates are diluted 1 + 4 with water for the processing and replenishment solutions. A starter solution is not required. 2000RT works very cleanly, and doesn't leave any impurities or deposits on the machine racks and rollers. It is very robust and long-lasting, even with strongly fluctuating throughput. 2000RT can be used in temperatures from 20 °C to 40 °C. For developing machines without replenishment the developer should be completely replaced after approximately 14 days; the fixer bath can remain in the machine for up to 1 month. For machines with replenishment the solutions should be replaced at least every 6 months. The solution usage duration also depends on the throughput of paper; a minimum weekly throughput of 2.8 square meters of paper per liter of tank solution is recommended; lower throughput requires higher replenishment rates and an evaporation compensation should be carried out. The developing time is based on the options of the developing machine. At 20 °C the minimum development time is 46 seconds, at 30 °C 22 seconds, and at 40 °C 12 seconds. Significantly longer development times should be avoided. At higher temperatures the fixing time should not be significantly shorter than the development time. If the temperature is more than 20 °C a fixing time of 20 seconds is adequate.
