KONSTITUENT-LAG SOM HOESTES FRA EN SENTRIFUGERT PROEVE I ETROER

摘要

PURPOSE: To make it possible to sample a target component in a safe state by eliminating riskiness that an inspecting engineer is brought into contact with contaminant substance. CONSTITUTION: A component layer is sampled from a plurality of centrifugally separated component materials in a deaeration tube made of glass or transparent plastic containing a float. When a substance possible to be contaminated like blood is inspected, if the tube is used, an inspecting engineer can measure it without contacting the blood. The tube 2 has the size capable of accommodating the flood of about 1ml, and is filled with low-pressure inert gas. A through hole is formed at the float 6, and the cell group to be sampled is gathered to the hole during the centrifugal separation. The group is gathered on a plasma layer during the centrifugal separation and held in the stable state by the layer of the fluidized substance for forming a membrane on the plasma layer. The cell layer to be sampled is sucked by a subcutaneous injector needle or canula inserted into the float bore 7 of the tube 2 from the bore 7.
