Multigrade developer is designed for use at ambient room temperatures, nominally 20°C/68°F.
It is not recommend for use with high temperature or machine processing applications.
Ilford Ilfotec HC is an economic, versatile, highly concentrated liquid developer for processing all general-purpose black and white films.
Using the appropriate dilution, it can be used in all process systems including: dishes (trays), small tanks, deep tanks, dip and dunk (hanger) processors, rotary tube processors, continuous long leader processors, roller transport processors and short leader card processors.
To use Ilfotec HC developer the concentrate is first diluted to make a stock solution. The developer stock solution must be further diluted for use.
The degree of dilution will depend on the film to be processed and the method of processing.
