The Environmental Sample Processor (ESP) is an in situ laboratory that collects and concentrates microorganisms or particulates from discrete water samples and automates the application of molecular probes to identify target species or toxins. Samples are collected onto 25mm membrane filters within multi-purpose reaction chambers called pucks. Analytical (array) pucks contain printed DNA or protein-based arrays designed to react only to specific rRNA or toxin targets. When the homogenized sample is exposed to the array, a chemiluminescent pattern develops which describes the detection and enumeration of multiple targets or toxins. The array is then imaged on-board with those images available for remote retrieval and analysis.

• Maximum depth: 50m with optional pressure housing.
• Number of samples: 44 (33 without archival sample); 132 puck capacity.
• Options: Platform is customizable to run secondary analytical modules.
