Abstract
A method of mixing at least one chemical concentrate with a thinning fluid to form a predetermined amount of a mixture or solution having a predetermined composition, particularly for use in photographic processing operations. Predetermined amounts of the concentrates are placed into respective holding units. The contents of the holding units are emptied into a mixing conduit which leads to a supply tank while at the same time thinning fluid is passed through the mixing conduit. The flow of thinning fluid through the mixing conduit is terminated when the amount of thinning fluid which has been passed through the mixing conduit reaches the amount corresponding to the predetermined amounts of the initial concentrates and to the predetermined amount of final solution or mixture desired.
