Apstein Type Plankton Net 50 cm ²⁶

Plankton Net acc. to Apstein: Excellence in Limnological Sampling

The industry-standard tool for qualitative and quantitative plankton collection, built for durability and precision in freshwater research.

The Plankton Net according to Apstein is a cornerstone of modern limnological investigation. This standardized, vertically operated net is specifically designed for qualitative studies of the water column. It features a high-grade 50 cm conical net bag attached to a 25 cm diameter stainless steel ring, ensuring a stable and reliable opening during deployment. Its hydrodynamic design allows researchers to capture representative biological samples with minimal disturbance.

A key feature of this system is the detachable net bucket, which facilitates easy sample retrieval. The bucket includes a weighted stainless steel ring for rapid vertical descent, a metal drain cock for precise sample release, and an integrated window covered with mesh fabric that matches the net bag. While the standard 55 µm mesh is ideal for phytoplankton, a wide range of sizes is available to suit specific research needs, from fine microplankton to larger zooplankton.
