Solinst 425D Deep Sampling Discrete Interval Sampler Part# 115342

The NEW 425-D Deep Sampling Discrete Interval Sampler can sample from submerged depths as much as 1200 m (4000 ft). The stainless steel sampler connects to the same convenient tubing reel as the standard 425. Operation follows the basic principles of hydraulics. The sealed sampler is pressurized at depth allowing water to enter. The sampler is vented and sealed before retrieval to surface, maintaining sample integrity.
