1-3/4" X 3' Stainless Steel Bottom Fill Double-Check Ball Bailer

Ideal for collecting discrete interval samples!

The Stainless Steel Bottom Fill Double-Check Ball Bailer is designed to be lowered down a water column inside a monitoring well, lagoon, estuary, etc. During the bailer's descent, liquid is able to pass freely through the sampler. Once the target depth is achieved, the bailer is then smoothly pulled to the surface. Due to the upper and lower check balls, a "discrete" interval sample will be trapped between the two. With the sample being “trapped”, mixing of other liquids is prevented while retrieving your sample.

Bailers offer an affordable and efficient grab sample, and they are available in a variety of lengths, diameters, and materials. They are widely used for shallow sampling and for sampling groundwater from monitoring wells in all phases of groundwater investigations. Stainless steel models may be decontaminated between uses; single-use, disposable models are also available.

Bailers are easy to use, relatively inexpensive – compared to hand pumping methods – and do not require a power source. They may be used to sample most depths, although deep sampling may be time-consuming.

Stainless steel bailers are used to collect composite samples from wells and boreholes. They feature a tubular body with a stainless steel loop bail and all models contain a stainless steel check ball except for the top fill model. The stainless steel body allows for quick and easy decontamination, and the tapered top on the 1-3/4" model allows for smoother raising and lowering.
