Built for reliable field sampling, this 1.6″ × 36″ weighted polyethylene (HDPE) bailer drops quickly to depth and fills cleanly. A single bottom check valve (ball-stop) seals fast to retain the sample, while the weld-less, rigid body resists warping. The large open top makes tie-off easy and speeds draining between pulls. Disposable construction streamlines decon and helps reduce cross-contamination risk.
