Supernatant Decanting on a Centrifugal Platform
This work presents a novel approach to decant and meter supernatant on a centrifugal platform. Supernatant decanting, such as decanting plasma from the centrifuged whole blood, is an important sample preparation procedure for the whole blood bioassays. By manipulating the centrifugally induced pressure and the elastic deformation of the chamber’s plastic lid, fixed amounts of the supernatant can be decanted into the detection chamber. This approach has the advantages of low manufacturing cost and ease of operation.
