These plankton nets have a frame diameter of 300mm and an 880mm long bag. They are constructed in-house at our workshop in Devon. Nets are available with a 20µm, 35µm, 53µm, 100µm, 150µm, 250µm, or 335µm nylon precision mesh bag and have a 50mm screw on filter with the same mesh size as the main body of the net. It is possible to purchase 50mm screw on filters in an array of mesh sizes. A 300ml collecting bottle (available separately) can be used with this net by purchasing the Collecting Bottle Adaptor, which replaces the standard filter. Alternatively, a Plankton Collecting Vial can be used, allowing you to siphon off exact volumes of sample.
The 7m towing line and harness mean the nets are suitable for towing behind a boat as well for use from a suitable bank, jetty or beach. The plankton net also includes weight loops which allow weights to be attached for sampling at greater depths. Please note that weights are not included with the net.
Plankton nets should be rinsed with freshwater after use and dried thoroughly to protect fixtures.
Please note: Our plankton nets are now fitted with a 50mm filter rather than 32mm and include weight loops.
