Overview
The Hess Sampler is a specialized tool designed for sampling macrobenthos in shallow, flowing waters, particularly in gravel and cobble-bottomed streams. With a cylindrical body, enclosed sides, and an open top, it ensures precise and efficient sample collection.
Key Features & Benefits:
✔ Ideal for Gravel & Cobble Bottoms – Designed to penetrate 3 – 6 inches (75 – 150 mm) for effective sampling in rugged streambeds.
✔ Strong Reversible Handles – Allows for firm pushing and rotating into the stream bottom for stable positioning.
✔ Efficient Water Flow Design – Water enters through the upstream window and exits via the downstream window, directing specimens into the collecting net and bucket.
✔ Effective Scrubbing Mechanism – Ensures collected pebbles are scrubbed to dislodge specimens, improving sample accuracy.
✔ Versatile Sampling – Can also be used as a Liquid Cup Sampler for point sampling of liquids with varying viscosity and media-containing particles.
A reliable solution for researchers and environmental scientists conducting benthic studies in shallow streams with gravel or cobble substrates.
