Supernatant liquid collector with balance weight forming function and centrifugal apparatus using the same

摘要

Primaiy supernatant liquid collector 1 allows blood A to separate into a primary supernatant liquid B and red blood cells by leaving the blood A stationary for a prescribed period of time, and then it discharges the primary supernatant liquid B and physiological saline W in the same amount into a first treatment container 13 and a first balance container 14, respectively. Centrifuge 61 centrifuges the above primary supernatant liquid B using the first balance container 14 as a balance weight, and a secondary supernatant liquid in the first treatment container 13 is transferred to a second treatment container 109 by take-out device 91 and at the same time the physiological saline W in the same amount as the transferred secondary supernatant liquid is transferred from the first balance container 14 to a second balance container 110.
