Click the button below to add the Aquatic Suction Sampler to your wish list.

Extract aquatic invertebrates from wet sand or loose muck using this durable, economy sampler! Just place the end of the sampler over the hole left by the invertebrate or over any other area where you suspect specimens are located. Pull up on the sampler's handle. An area of negative pressure is formed in the void and the substrate as the inner piston moves up the sampler's housing, allowing the specimens to be securely drawn inside. Made of heavy duty PVC, hardwood, and rubber. Not recommended for use in clay-based mud. Dimensions 42"L x 2 1/14" diameter
