The EcoBailer Weighted Polyethylene Disposable Bailer is designed for dependable groundwater sampling in environmental monitoring wells, water quality testing programs, and site investigation projects. Built for professional field use, this disposable bailer provides a practical solution for collecting groundwater samples while supporting efficient field sampling procedures. EcoBailer bailers are manufactured from polyethylene and feature a thicker tube wall design than many competing disposable bailers. This thicker wall construction helps the bailer maintain its shape during handling and deployment into monitoring wells. Maintaining tube shape during sampling helps ensure smoother travel through the well column and consistent sampling performance. The EcoBailer incorporates a hydrodynamic tube design with a wider pour spout opening, allowing the bailer to descend efficiently through the water column. This design helps support a faster sink rate while minimizing dissolved oxygen changes in the collected well sample.
