Product Description The Robotic Cartridge Sampling Instrument (RoCSI), is a biomolecular sampler that performs in-situ sample collection and preservation onto 0.22 µm or 0.45 µm Sterivex™ filter cartridges. RoCSI features high sample count capabilities in a compact instrument, that is depth-rated to 6,000 m. Cartridges are stored on a continuous sample belt and are rotated into position for sampling or injecting preservative. The compact size and user-defined sample capacity make the RoCSI ideal for vehicle integration, long-term mooring systems, buoy mounts, bottom landers and ship-board applications.
