Method and apparatus for sampling liquid phase components from a liquid-semisolid fluid

摘要: To sample liquid phase components of a biological fluid which has been subjected to centrifugation separate its and semisolid define liquid-semisolid interface therebetween, probe carrying sensor at end is extended into through the until detects interface, whereupon further extension halted. A then withdrawn openings in spaced from so that only are sampled. It contemplated stopper close vessel containing fluid, be movable within needle first pierces stopper, may moved vessel. also aseptically transferred receiving vessel, cleansed with flushing solution between sampling operations.
