Claims7
A sampling device comprising:
- an outer tube including, at one end thereof, a nose portion for penetrating material to be sampled, said nose portion having at least one aperture therein;
- and
- at least one inner tube mounted within said outer tube for receiving the material to be sampled, each said at least one inner tube having at least one further aperture positioned eccentrically to said outer tube, the mounting being such that, except for the nose portion, in any cross sectional plane normal to central longitudinal axes of each tube and containing cross sections of each tube, the cross section of the at least one inner tube is completely within the cross-section of the outer tube;
- each of said at least one inner tube being movable relative to said outer tube between a first position, wherein said at least one further aperture of each of said at least one inner tube is aligned with a respective one of said at least one aperture, and a second position, wherein said at least one further aperture of each of said at least one inner tube is closed by said nose portion.
