Sediment-Behaelter fuer Zentrifugen und Kappe fuer derartige Behaelter

摘要

Medical testing apparatus including a centrifuge with a series of cuvettes received therein. The cuvettes may be discrete units or arranged in groups which make up cassettes. Each of the cuvettes has a test chamber or reaction chamber into which reagents and specimen pass during the centrifuging operation. The reagents are contained prior to centrifuging in plastic bags which include intentionally weak seams designed to fail during centrifuging and to permit the reagents to flow into the reaction chamber. The specimen is contained within a pipette tip closed by a cap. The cap is also designed to fail or, in other words, be centrifuged off of the pipette tip in order to permit the blood serum or plasma in the pipette tip to flow past the cap and into the reaction chamber after the red blood cells have been packed down into the cap by the centrifuging operation. After centrifuging, the cuvettes can be removed from the centrifuge and placed into a photometer to determine the amount of light passed or the amount of light passed can be determined directly while the cuvettes are being spun or turned in the centrifuge by a photometer.
