Bailer: 0.75" × 36" Disposable, Unweighted, Teflon Bailer coating integrity test Flow control is accomplished bySKU 71771 Bailer Dis Teflon UW 0. 75" 36" A disposable, unweighted Teflon (PTFE) bailer at 0. 75" diameter the premium material option in the narrow diameter bailer lineup. What it is: A 0. 75" diameter 36" long Teflon (PTFE) tube with a bottom check valve Dis = disposable (single use, no decon required) UW = unweighted Why Teflon matters: PTFE (Teflon) is chemically inert to virtually all groundwater contaminants it won't leach, adsorb, or react with
