  Discrete Interval Sampler

---

The Solinst Discrete Interval Sampler is a high quality stainless steel sampler with Teflon ball valves and Viton o-rings. It is connected to a narrow diameter air tube on a reel. The sampler is pressurised before lowering into the borehole. This prevents any flow of water into the sampler during descent through the water column. Once the sample depth is reached, the air pressure is vented, and the sampler fills. Once full, the sampler can be repressurised to maintain in-situ pressure and then brought to surface. Samples can be collected at surface using the built-in Sample Release Device (SRD) or transported pressurised directly to a laboratory.

The sampler is ideal for groundwater sampling below an oil/product layer, for retrieving heavy oil (DNAPL) samples or for volatile and dissolved gas sampling of groundwater in boreholes.
