The ASC Model SQ-600 Sediment Pore Water Extraction System is designed for high-pressure extraction of pore water from marine and lacustrine sediments.

The unit is constructed so that the only metallic surfaces in contact with sample are titanium. The base of the squeezing chamber incorporates a titanium screen which supports a filter paper through which the pore water passes before collection in a syringe.
