Hydro- Bios Neuston Net acc. to David/Hempel Model 300

Neuston Net acc. to David/Hempel Model 300

Plankton net for sampling surface and sub-surface fauna

ABOUT

The Neuston Net acc. to David/Hempel Model 300 has been designed for accurate epineuston and hyponeuston sampling. A current field of application is e.g. microplastic sampling. It consists of a slender catamaran swimmer body of aluminium with relative high draft, caring for a stable position even under choppy conditions at sea. The vertically adjustable double net frame receives the rectangular surface and sub-surface net bags with a standard mesh size of 300 microns (or as per choice between 100 and 500 microns). For easy retrieval the sample is concentrated inside two removable plastic net buckets with side window (covered with sieve gauze). A bridle with one adjustable leg is used to operate the net from starboard, portside or stern.
