SUBSTANCE: sampler of loose materials has body anchored on vessel with loose material, sampling chamber manufactured in the form of spring, dissector made fast to sampling chamber, handwheel attached to one end of sampling chamber. The latter is equipped with charging trough fabricated in the form of hollow finger which upper part is cut away to half-diameter along its length and which end interacts with dissector under pressure on trough. Body has internal thread whose pitch corresponds to spacing of turns of sampling chamber. Proposed sample makes it possible to take samples from apparatuses with chemically active loose materials releasing harmful vapors and gases into atmosphere. Sampler is simple in design, takes samples both close to walls of apparatus and in radial direction, allows examined loose material to be stirred before sample of it is taken.
