Weighted Teflon Bailers
The most durable disposable bailers on the market.
Teflon Bailers are used to purge and retrieve samples from 2-inch and larger wells having special chemical sampling needs and with very low ppb or sub-ppb concentrations. Disposable Teflon bailers are desirable because they eliminate the labor and uncertainty of cleaning and reusing.
Teflon bailers are chemically-resistant, have a clear body, and are available either 12" or 36" lengths and either weighted or unweighted. Teflon Bailers aren't as rigid as poly bailers, they are clear for viewing contents during sampling.
