Abstract
Methods for using a centrifuge are presented. A vessel containing a sample and a separator substance is placed within a centrifuge. Upon sufficient centrifugation, the sample separates into two or more fractions separated by the separator substance. The centrifuge exposes the separator substance to a sufficient energy to polymerize the separator substance to produce a hardened barrier between the fractions.
Claims14
A centrifuge system comprising:
- A curable separator substance having a density intermediate between at least two fractions of a blood sample;
- A sample containing vessel sized and dimensioned to receive the curable separator substance;
- A vessel holder sized and dimensioned to receive the sample containing vessel;
- A rotor coupled to the vessel holder and configured to centrifuge the sample containing vessel held within the vessel holder;
- and
- An energy source adapted to expose the curable separator substance in a held, centrifuged vessel to curing energy sufficient to cure the separator substance to solidity.
