ABSTRACT:
The disclosure is of an improved assembly, compositions and method for the separation of blood into its light, liquid and heavy, substantially cellular phases with insertion of a non-Newtonian fluid between the phases as a barrier. The improvement comprises using as the non-Newtonian fluid, one which has substantially time independent rheological properties and a controlled yield stress value. The improved assemblies of the invention have enhanced shelf-lives and improved reliability of operation. The preferred assemblies may be sterilized by irradiation and the disclosure is also of a method for their manufacture.
