It boasts long shelf life, high capacity, compatible with soft to very hard tap water up to a hardness of 500ppm, and easy transport for travelling to suit all consumers' needs.
The fixer is sodium thiosulphate based and free from: borate derivatives, non-biodegradable DPTA and EDTA, phosphates, acetic acid, known carcinogens and mutagens to make is more friendly to the environment.
By having little odor, the fixer will provide a more pleasant working environment in the darkroom. The slight alkaline nature of the fixer makes film more resistant to over-fixing and fast washing out for film and paper without a need for hypo-clear. An acid stop bath is not required and water stop is perfectly sufficient meaning less chemicals are required. By being non-hardening, this fixer allows for easier bleaching and toning when printing.
