ABSTRACT:
A centrifuge rotor has vertically oriented peripheral cavities and/or adaptors configured to receive sample containers each having a length which exceeds its diamter. Each cavity and/or adaptor is provided with a cap and/or an adaptor cap which together provide a rigid support and seal for each sample container. With this apparatus the separation gradient reorients from horizontal during separation to vertical during sample removal providing the advantages of reduced separation time and improved resolution.
