A device and method for separating a fluid component from a non-fluid component of a sample comprises a plurality of microspheres disposed in abutting relation and forming therebetween a plurality of capillary channels, whereby when the microspheres are disposed in fluid communication with a sample the fluid component is separated from the non-fluid component by capillary flow of the fluid component through the capillary channels formed by the interstitial spacing between abutting microspheres. |
