Dip Net Surber Sampler: Precision Benthic Sampling for Running Waters

The definitive kick-net sampler for aquatic macroinvertebrate studies, featuring a foldable frame design that defines an exact sampling area on the stream bed.

The Surber Sampler is a specialized tool designed for the rigorous collection of aquatic insects, larvae, and other forms of life inhabiting shallow flowing waters. Unlike standard dip nets, the Surber type utilizes a unique down-foldable stainless steel frame that delineates a precise area on the ground. By disturbing the substrate within this fixed boundary, researchers can effectively collect organic and inorganic solids swirled up by the current, ensuring quantitative accuracy in every sample taken from the watercourse bottom.

Built for durability and ease of use in the field, the sampler features a high-quality MOnyl (PA 6.6) net bag that is both detachable and equipped with a zip fastener for fast dismounting and cleaning. The rugged stainless steel frame includes a 20 mm inner diameter receiver, allowing for the quick attachment of a telescopic rod to extend the researcher's reach. Ideal for water depths between 30 and 45 cm, this sampler is an essential instrument for limnologists and environmental monitors dedicated to the preservation and study of aquatic biodiversity.
