ABout

The Plankton Nets acc. to Apstein, used in limnological investigations, are manufactured in various shapes and sizes. The basic versions, intended for qualitative collections, comprise a stainless steel ring to which a conical net bag is attached. For easy retrieval the sample is concentrated inside a removable net bucket with sieve gauze covered side window. The standard mesh size of the Plankton Nets acc. to Apstein is 55 micron, which is used for the collection of phytoplankton.

For collection of zooplankton the nets are available with a mesh size of 335 µm. For special requirements select mesh sizes between 55 and 780 µm (Mesh sizes below 55 µm are available at extra charge).
