ABSTRACT:
A improved disposable bailer which is made of a pliant or flexible transparent tubing material for the collection of fluids and/or gases. The present invention allows sampling in minimally sized bores or wells which are not perfectly straight. Also, the invention permits sampling at the top of a fluid column or within a fluid column and permits acquisition of a vapor sample on top of the fluid column. In this embodiment, a vapor or liquid specimen may be sampled through a septum on the surface of the bailer. Also in this embodiment, fluids and gases may be collected through a flexible nozzle which acts as a valve when the collected sample constricts the nozzle opening due to the presence of the collected sample in the tubing. In another embodiment, samples are collected through the top of the tubing, allowing selective sampling within a column of fluid when the tubing is immersed. Another embodiment utilizes both the flexible nozzle and top opening to collect samples. Perforated strips applied across either or both ends, breakage of which is preferably necessary for use, indicate usage or tampering.
