Abstract

Particles contained in a small amount of liquid are classified simply and instantaneously. The apparatus has a liquid introduction port (1A) for introduction of a liquid containing particles and a particle classification part (1B) provided in communication with the liquid introduction port (1A) so as to not only introduce the liquid into the interior by capillary phenomenon but also separate the particles contained in the liquid in accordance with the particle diameters, characterized in that the particle classification part (1B) consists of planes (11a,12a) opposite to each other, which opposite planes (11a,12a) have multiple interstices different from each other.
