Solinst 425 Discrete Interval Sampler Sub-Slab A complete 415 system includes:The Solinst 425 Discrete Interval Sampler collects a groundwater sample from one exact depth without mixing it with water from other depths in the well column. Before lowering, the stainless steel sampler body is pressurized through its tubing so water cannot enter it. It is lowered on a suspension safety line to the exact target depth, then the pressure is released (vented). A floating check ball inside the sampler body (PTFE ball, which sinks, at
