Disclosed therein is a sampler. The sampler includes: a chamber accommodating a fluid or solid reagent therein and being sealed at both ends with penetrable films; a tube joined with the chamber at one side, the tube having a hollow portion therein; and a movable bar having a tip which is formed at one end and has a specimen extracting portion, the tip being guided and moved through a hollow portion, the tip being adapted for mixing the specimen extracted by the specimen extracting portion with the reagent so as to form a diluted solution while penetrating through one end of the chamber and adapted for quantitatively discharging out the diluted solution while penetrating through the other end of the chamber.

Sampler

Disclosed is a channel filter for separating microparticles, and more particularly to a channel filter which can easily separate a sample having various sized microparticles by using a surface topology. In the disclosed channel filter, a topology having an upward/downward reference height from a sample inlet to an outlet is continuously or discontinuously formed, and thus it is possible to efficiently separate microparticles from a sample liquid.
