CONSTITUTION: A sampling device comprises a main pipe(110), two or more sampling members(A,B), and a sampling control member(140). The main pipe is inserted into a sample filled inside a vessel. The sampling members collect the sample through two or more sampling holes formed in the main pipe at a constant distance.
