The 425D Discrete Interval Sampler from Solinst obtains representative water samples from a specific zone without the need for purging. It can sample from submerged depths as much as 1200 m (4000 ft). The stainless-steel sampler is connected to LDPE tubing, mounted on a convenient reel. Operation follows the basic principles of hydraulics. The sealed sampler is pressurised at depth allowing water to enter. The sampler is vented and sealed before retrieval to surface, maintaining sample integrity. Ideal for obtaining water samples from below floating product layers (LNAPL), or sampling the product itself.
