DEVICE FOR TAKING UNDISTURBED AND PRESSURIZED SAMPLES OF GROUND-WATER (AND GAS) IN OPEN SYSTEMS

摘要

Sampling device for taking pressurized samples of liquid and/or gas. The sampling device contains a hermetically sealed and an at least partly evacuated sample container (9). The sample container is sealed by an element (23) of flexible material. The sampling device does also contain a double-ended hypodermic needle (16). When activating the sampling device, which is made by applying an over-pressure, the hypodermic needle (16) penetrates through the element (23) of flexible material whereby a sample is being transferred to the sample container (9).
