Discrete Interval Sampler

solinst discrete interval sampler no purge groundwater sampling

The 425 Discrete Interval Sampler is excellent for obtaining no purge groundwater samples from below product layers, within product layers, and for sampling at discrete depths in a well. It is pressurized with a hand pump before entering the well. No water flows through the sampler on the way down the well. When the pressure is released, the sampler fills directly from the sampling zone.
