Bailer: 3" × 36" Disposable, Unweighted Polyethylene Groundwater Bailer PURCHASE Its compact designSKU 71749 Bailer Dis Poly UW 3" 36" This is the unweighted counterpart to 71747 a disposable, 3" polyethylene bailer for large diameter monitoring wells, without the added weight. What it is: A 3" diameter 36" long polyethylene (poly) tube with a bottom check valve Dis = disposable (single use, no decon required) UW = unweighted When to choose unweighted (71749) over weighted (71747): Shallower wells where gravity alone is sufficient to sink the
