<p>The probe for extracting samples from below the earth surface has an elongate body (1) with a hollow core. The longitudinal axis of the hollow core is inclined at a small angle to the longitudinal axis of the body so that it extends from one end (3) of the body to a side outlet (4). The other end (5) of the body can engage with a drive rod or a powered hammer mill.</p> |
