  • Cleansing composition for electronic particle counting apparatus; and method for its use
    Patent number: 4384971
    Abstract: An isotonic cleansing agent and method for its use in electronic instrumentation systems for determining hematological components of blood samples are described. The cleansing agent comprises an aqueous solution of a non-hemolytic polyoxyethylated alkylphenol detergent, dimethylolurea, and an isotonic and isoconductive saline base which is free of phosphates. The dimethylolurea serves as a cell stabilizer, and also acts as a germicidal agent, together with other added germicidal agents, particularly sodium 1-hydroxypyridine-2-thione.
