The sampler can run sampling up to 4 different mesh sizes during one deployment, while keeping a precise account on the total volume, measured by a flow meter. The filter plates themselves can easily be removed thus supporting pumping with fewer or none filters at all (demands one or more dummy rings).

Due to its very flexible range of filter sizes (ranging from 1000 µm down to 100 µm), it has proven itself a very useful tool in sampling plastic particles, mostly used in lakes and shallow water. Other sizes (down to 20 µm) on request; in general, we recommend 50 µm as a minimum; a small mesh size may clog very fast thus reducing the pump's capacity.

As a counter part to the more well-known Manta Trawl net the pump's counter gives users a digital read-out of amount of water, ensuring them a very precise data that is fully able to be compared with other samples done with similar pumps with very high scientific guarantees; this is primary due to the fact that the water pumped is first measured after it has gone through the filters preventing any faulty data with organic material clogging up the filter sample area.

Standard delivery comes with 10 m of cable for the power supply.

The flow meter read-out (max. value 99999) vs. water volume can be calculated using our spreadsheet allowing a quick and intuitive conversion regardless if the shape is circular, square or rectangular. Find the spreadsheet here.

IMPORTANT: The pump must be deployed by a separate steel wire or similar, as the cable cannot bear the pump's weight. Deploying this pump requires a constant relief of the cable in its entire length, to avoid any cable damage because of the cable's weight.
