Discrete Interval Sampler

solinst discrete interval groundwater sampler

425 Discrete Interval Samplers are 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.

The 425-D Deep Sampling Discrete Interval Sampler is available for sampling from submerged depths of 1200 m (4000 ft). Its operation is based on the basic principles of hydraulics.
