  KC sediment trap, O.D. 80 or 110 mm
28.100 - sediment tube sampler with 2 tubes. Total sample: 3,8 liter
28.100 - Sediment trap. 2-Tube.

28.200 - sediment tube sampler with 2 tubes. Total sample: 7,6 liter
28.200 - Sediment trap 4-Tube.
General:
The construction of the sediment trap array ensures a permantly vertical position of the sampling tubes during deployment. The steering fin (optional) and the pivot joints force the array to be held at right angle to the current.

Options:
The system is fully configurable. All parts are detachable and the main rack can be attached with 1, 2, 3 or 4 tubes to suit your needs for analysis.

The Sediment Trap consist of detachable cylindrical sampling tubes mounted with lead weights at the bottom. The gimbaled tube holders and fin are made of AISI 316 stainless steel. The tubes are made of transparent acrylic and have an aspect ratio above 6.

Available models: 
Ø80/Ø72 mm and Ø110/Ø104 mm.
1, 2, 3 or 4 traps, se below. 

All sizes of tubes can be manufactured upon request.

The Sediment Trap has been developed in cooperation with associate professor Michael Olesen, from the Marine Biological Laboratory, University of Copenhagen, Denmark.

The schematics are for your general information. KC-Denmark cannot
estimate any details for buoys, anchors etc., as local conditions, current
and depth range, etc., are to be considered and tested in practice.
