Abstract
This invention relates to a device for taking samples of ground water in soil and rock, comprising an at least partially evacuated sampling container of which the end facing downward in operative position is sealed air-tight by a first member of flexible material. The object of the invention is to improve the existing art for taking ground water samples in soil and rock. The device according to the invention renders it possible to take samples, which are hermetically sealed until they are analyzed in the laboratory. The device according to the invention is characterized, in that a second member of flexible material closes the upper end of the ground water sampler, and a two-sided cannula is movable in its longitudinal direction relative to the two members.
Claims12
A device for taking at least one ground water sample in soil and rock, comprising a movable element having an at least partially evacuated sampling container, an end of the container facing downward being sealed air-tight by a first member of a flexible material, the device further including a ground water collector, a second member of flexible material closing an upper end of the ground water collector, and a cannula with two pointed ends arranged between said first and second members, means for selectively moving the cannula in its longitudinal direction relative to the two members for selectively penetrating the first and second members with a respective one of the ends for transferring a ground water sample from the collector to the sampling container.
