1. a microfluidic devices, comprising:

  • Sample dispense net, described sample dispense net comprises;

    Multiple sample chamber, described multiple sample chamber is arranged to load with biological sample, for the biological test carrying out biological sample in sample chamber,Multiple intake vent, flow and are communicated with and are arranged to make biological sample flow to respective sample room in each intake vent and respective sample room,Multiple exit passageway, flow and are communicated with and are arranged to biological sample is flowed from respective sample room in each exit passageway and respective sample room,Wherein, at least some in described sample chamber comprises dry reagent, and the reagent of described drying is arranged on the on the suction side of the close intake vent of described at least some sample chamber, and intake vent flows with described at least some sample chamber and is communicated with;

    AndWherein, described sample chamber has so configuration so that produce the more balance of the power acted on described biological sample when described biological sample loads described sample chamber or distribute uniformly, and/or have the leading part stopping that effect makes the meniscus of described biological sample or the driven member slowed down, thus the part lagged behind of described meniscus is made to advance to the position identical with described leading part if having time.
