Model 425 Discrete Interval Sampler
Available from Solinst Canada Ltd
The Discrete Interval Sampler is stainless steel, attached to LDPE tubing mounted on a convenient reel. It is pressurized before being lowered to prevent water from entering the sampler until the desired zone is reached. Used to profile open bodies of water and boreholes, and collect discrete samples. Ideal for obtaining truly representative samples of water below product or product itself (LNAPL or DNAPL).
