Product Overview

The Solinst Model 425 Discrete Interval Sampler (DIS) is a stainless-steel sampler, with LDPE tubing mounted on the convenient Solinst reel. The reel has a pressure attachment for a high-pressure hand pump and a pressure/vent switch which is used to apply and release the pressure on the sampler. A sample release device is included with each Discrete Interval Sampler. Operation The sampler is pressurized before being lowered into the well to prevent water flowing into the sampler. Once the desired depth is reached, the pressure is released, and hydrostatic pressure fills the sampler with water directly from the sampling zone. A floating check ball inside the 1.66"ø (42 mm) and 1"ø (25 mm) samplers prevents water from entering the tubing, thus avoiding the need to decontaminate the tubing.
