ABSTRACT:
A systematic and programmed wash cycle for cleaning automatic and semi-automatic biochemical analyzers and separators and other equipment. The wash cycle includes a series or sequence of specific and ordered washing steps using a fixed specific sequence of reagents in critical concentrations including use of a hypochlorite reducing agent, a peroxide oxidising agent, an alkaline hydroxide solution, a solution of cetyl pyridinium bromide and cinnamic aldehyde, a solution of a polysulfonated alkyl detergent and a hydrochloric acid solution. It is also contemplated as a special feature, to use a so-called "polishing" system to eliminate from analyzers the micro-organisms and enzymes which cause interference with UV analyses. It is also a particular feature that the ordered wash cycle can be used to clean tubular flow systems, including piping and plumbing, such as may occur in centralized air conditioning units and miscellaneous washing machinery.
