The Permanent PVC Bailer is an investment in long-term sampling. It comes in a variety of lengths and diameters, or call for special pricing on custom bailers up to 7 feet in length. Prior to re-use, the bottom check valve can be unscrewed and removed, allowing each internal part to be decontaminated and rinsed. To extend the length of a permanent bailer, attachable extensions in lengths from 1 to 6 feet can be purchased by contacting us. Whatever the situation might be, Aqua Bailers can adapt our products to fit your business’s needs.
