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
