The Model 425 Discrete Interval Sampler is a stainless steel groundwater sampler, with LDPE tubing mounted on a convenient reel. Discrete interval sampling is ideal for obtaining truly representative groundwater samples from below floating product layers, or for obtaining samples of the product itself. The Discrete Interval Sampler can also be used to profile open bodies of water, boreholes, and to collect samples from distinct levels or points of inflow. The Discrete Interval Sampler is a passive sampler that is pressurized when lowered and upon retrieval, to prevent water mixing at different levels. Designed to give zero purge samples.

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 checkball 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.

When the sampler is filled, it can be repressurized and raised to the surface. The sample is decanted using the sample release device, which regulates flow and minimizes degassing of the sample. The sampler is easily disassembled for decontamination.

Biodegradable disposable PVC bailers and stainless steel Point Source Bailers are also available from Solinst (see Model 428 BioBailer & 429 Point Source Bailer Data Sheets).
