Abstract

A microfluidic device provides separation of particles in a liquid sample, particularly, separation of a sample of whole blood into its components for further analysis. Separation into red blood cells and plasma occurs within a few seconds after the blood sample has been transferred from a sample well (12) into a separation chamber (14) with the application of centrifugal force of less than one up to about five times gravity. With the application of greater force measurement of hematocrit is possible.
