| 摘要 |
<p>The invention relates to a method of making a thixotropic gel for partitioning separated phases of a fluid sample, the phases having differing densities and the gel having a density intermediate those of the phases, wherein a silicone fluid, a filler material and a network former are reacted to form the gel, characterised in that the silicone fluid has a first viscosity and comprises a single stock fluid or a blend comprising at least two blend stock fluids, each said stock fluid in the blend having a viscosity within about +/-15% of said first viscosity, and said gel-forming reaction is carried out at or below about 120 DEG C. The gel produced is primarily intended for partitioning the serum and clot portions of a blood sample. The invention includes a fluid sample collecting and separating device incorporating the gels of the invention. </p> |
