Petite Ponar Grab Sampler

A compact stainless steel grab sampler that helps students collect consistent benthic samples from freshwater environments for classroom and field investigations.

• Stainless steel construction for corrosion resistance and long-term use in water sampling 6×6" opening designed for focused benthic material collection

  Even-weighted jaws help ensure consistent grab sampling performance

  Works well for sediment and bottom material studies in ponds, lakes, and streams

  Supports NGSS performance expectations related to ecosystems and environmental change (e.g., MS-ESS3-3, HS-ESS3-1)

The Petite Ponar sampler is a compact, all-stainless steel grab sampler used to collect material from the bottoms of freshwater bodies. Its 6×6" jaw configuration and even weight distribution help ensure that students collect consistent samples of benthic material during field studies. The stainless steel design resists corrosion and withstands repeated use, making it practical for classroom excursions, environmental science labs, and outdoor investigations.

Students can deploy the Ponar to the bottom of a stream, pond, or lake and retrieve substrate samples to examine sediment composition, organism habitat, or human impacts on aquatic ecosystems. By comparing samples from multiple locations or times, learners build skills in observation, data collection, and interpretation, reinforcing classroom lessons on ecosystem structure, environmental change, and watershed dynamics.
