Abstract

A micro-liter liquid sample, particularly a biological sample, is analyzed in a device employing centrifugal and capillary forces. The sample is moved through one or more sample wells arrayed within a small flat chip via interconnecting capillary passageways. The passageways may be either hydrophobic or hydrophilic and may include hydrophobic or hydrophilic capillary stops.
