FIELD: physics. ^ SUBSTANCE: sample collection device has housing with end sealing, a sampling tube with a shutoff cock and a flexible reinforced hose with a ferromagnetic tip and a permanent magnet. A hollow casing made from diamagnetic or paramagnetic material is placed vertically and air-tightly from the bottom to the top in the container and inside the said case on the entire height of the container there is a linear permanent magnet motor mounted to a motor scanning inductor through lining made from magnetically permeable material and capable of vertical displacement on a fixed secondary element of the electric motor together with its inductor and stopping at the required point of the secondary element. The ferromagnetic tip of the flexible hose, held in such a position by magnetic attraction force, is constantly located opposite the permanent magnet outside the casing. ^ EFFECT: interval-wise collection of liquid and gas from a container. ^ 2 cl, 1 dwg |
