Multi Corers | Corers | Box Core Samplers | Dredge Samplers | Grab Samplers | Water Sampling Bottles | Sediment Trap | Plankton Nets | Bongo Nets | Plankton Net Accessories | Invertebrate Sampling | Hand Nets / Pond Dip Nets

There are a range of Multi Corers available, designed to take virtually undisturbed multiple samples from shelf, bathyal and abyssal sediments. All the devices have sampling tubes that are capped at the top and bottom, encapsulating the sediment and overlying surface water interface within the corer tubes. These corer tubes or, in certain instances the whole corer tube assembly, can be removed from the main body of the corer enabling a succession of samples to be taken during any one mission. The devices have weight frames, enabling additional ballast to be added when necessary. Vertical hydraulic core sample extruder systems are also available.

Deep Sea Multi Corer - these are available in configurations of 4, 6, 8, 10 and 12 tubes, with tube sizes of 57mm diam. x 610mm in length or 100mm diam. x 700mm in length (other lengths and diameters available on request). Approximate weight 700kg, operational depth 6000m.
