ABSTRACT:
Sampling apparatus is disclosed for liquids, such as water, including cup-shaped members fixed to one another in partial telescoping relation with their closed end portions opposed. A piston disposed within the inner cup-shaped member contacts its walls and is adapted for reversible travel longitudinally of that member. The apparatus carries sampling, one-way valve means adapted to open only for intake. Conduit means connects the one-way valve means to the interior of the inner cup-shaped member between its closed end portion and the piston. In operation, the piston forces a liquid from the sampling area within the telescoping cup-shaped members while simultaneously refilling the evacuated area, due to the resulting reduced pressure, with the liquid to be sampled.
