Aqua disposable Poly Bailers are constructed using 100% pure virgin polyethylene. Now part of a family of “weldless” bailer design, the Poly Bailers strict part and production requirements have virtually eliminated any leakage when sampling in the field. Additionally, the large open-top design allows nearly an inch of open space for an easy tie-on. The Poly bailer has a thick, rigid construction and will not warp or collapse during sample. By using a PVC ball and a steel weight triple-coated with Teflon®-based non-chip paint, your sample stays securely in the bailer during testing.
