Sediment Trap 21 sample bottles

Sediment Trap - SSF21

Sediment trap

Sediment traps are used to investigate the vertical flux of particles in a water column for deployment in both oceans and inland waters.

They are descended to a certain water depth where sinking particles are picked up through a funnel and then collected into sample bottles. The collected material enables qualitative and quantitative investigations of its biological, chemical and mineralogical composition.

The housing is an open framework to reduce the current resistance. Its almost hexagonal shape enables traps to be easily linked together in order to cover larger areas.

The sediment is collected through a funnel which is fixed to the framework. A hexagonal lattice grid baffle made of special sealed paper is used to cover the funnel. This serves as current stabilizer and also reduces wash out.

The control unit with battery compartment and the drive unit are placed above the collection turntable. They are mechanically separated and linked together with an underwater cable. An easy mounting and demounting of the control unit for programming, battery change and maintenance is guaranteed.

The multi bottle sample collection turntable exists of a basic plate under which the sample are aligned in a circle at an axial face seal ring. The drive unit places the sample bottles sequently under the funnel`s bottom orifice. Through a special construction it is guaranteed that all the other sample bottles not being in use are sealed against the outer medium..

Types of Sediment Traps

The multi bottle sample collection turntables are available with a funnel diameter of 0,25m² or 0,5m², the funnel slope angle is at 34° each.

All Sediment Traps are equipped with the lattice grid baffle as funnel cover and the single-side suspension. The scope of supply contains a maintenance set, a manual as well as the software.
