The 428 BioBailer is an inexpensive, reusable, biodegradable bailer made from clear, high-quality PVC pipe. Capable of holding more than one litre of sample material, it features a dense, robust body with tapered ends. The 428 was designed to prevent well hangups, and weights are unnecessary for most applications. The transparent PVC construction enables samples to be visually checked on-site for product or water. Samples are obtained by lowering the bailer down the water column and allowing water to enter the bio-bailer from the base via a non-return ball valve. As the Bio-bailer material is denser than water, it naturally sinks under its own weight. As the bailer is retrieved the check-ball sinks to the bottom of the bailer to traps the obtained sample within the bailer.
