  • Groundwater sampler
    Patent number: 5485881
    Abstract: For extracting samples of groundwater from a borehole. A down-hole fixture has a check-valve positioned at the foot of the borehole. A sampler is lowered down into the borehole. Pushing down on the sampler causes a stem on the sampler to unseat the check-valve, communicating groundwater with the sampler. A plastic tube running from the sampler to the surface transmits the push from the surface, required to operate the down-hole valve.
