Envco – Environmental Equipment

There’s no place to hide from this sucker! Our durable sampler easily extracts burrowing aquatic invertebrates from wet sand and loose muck. Just place the end over a likely hole. 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.
