SAMPLER Russian patent published in 2013 - IPC G01N1/10 

FIELD: testing equipment.

SUBSTANCE: sampler comprises a body (1), a probe tube (3), a drill tube (4), capable of translational-rotational motion, a handle (5), connected to a drill tube (4), a clamping table (6) to fix a reservoir (2) with the tested liquid sample, a nozzle (7, 8). The drill tube (4) comprises a tubular body part with a side hole and a working part made in the form of at least four cutting edges placed at the angle to the axis of the drill tube (4) with equal angular pitch between them, being arranged symmetrically and evenly along the circumference, directed opposite to direction of rotation. Ends of cutting edges arranged near the drill tube (4) are placed at the angle of 0.2 to the plane perpendicular to the axis of the drill tube (4). The probe tube (3) is arranged coaxially with the drill tube (4). The body (1) directly adjoins the perforated plug of the reservoir (2) with the investigated liquid sample. The probe tube (3) with one end is connected with a nozzle (7) to create the first port for connection into a metering circuit. The drill tube (4) via a side hole in the body part is connected with a nozzle (8) to create the second port for connection into a metering circuit.

EFFECT: increased efficiency of sampling due to reduction of axial force at a handle in process of reservoir wall perforation.
