ABSTRACT:
A pre-packaged blood collecting and separating device and process of its preparation are disclosed in which the device contains a mixture of liquid polybutadiene and an inorganic, inert filler, such as silica, as a thixotropic gel adapted at rest to form a sealing barrier between separated blood phases. The device and gel are subjected to sterilizing radiation to form a substantially sterile device, substantially free of backflow contamination, without degradation of the physical properties of the gel.
