PURPOSE: An apparatus for collection of powdery sample is provided to eliminate factors deriving flying and/or dispersion of the sample and harmful vapors caused by pressure condition and temperature difference inside/outside of a sealed chamber and to reduce sampling error. CONSTITUTION: The apparatus comprises a cylindrical sampling duct(2) to be opened by a cap(4) of a suite(1); an output pipe(2b) to be opened by a cap(10) at bottom side of the duct(2); a curve(3) having a groove(3c) and a curve handle(3a) at top portion of the duct(2); a container(5d) to carry powdery sample; an output duct(2b) fixed on one side wall of the duct(2) and an outlet(5b) in a sampling device(5); an operational element(6) extending to the outside of the cap(4); and an operational knob(7) at front end of the element(6) to move the sampling device(5) to the inside/outside of the suite(1).
