The KC BIOLOGICAL DREDGE is made of heavy duty AISI 316 stainless steel. The triangular frame is furnished with a row of teeth guiding plants and algae into the bottom of the net.

A coarse meshed 2 cm Nylon net of 100 cm length for collecting biological and/or mineralogical samples is mounted on the frame.

A fine meshed net can on request be mounted inside the coarse net for collection of zooplankton.

The dredge is held in position by guiding arms welded to each corner.
