ABSTRACT:
Applicant's invention is of an improved liquid sampling apparatus designed for collection of liquid, typically water, for sampling purposes. The improvement to existing bailer designs lies in re-contouring the proximal and distal surfaces to avoid the potentially costly effects of a presently available bailer's angular margins lodging against irregularities on the surface of well casings. The terminal ends of Applicant's bailer are generally dome-shaped, thereby eliminating angular margins which can engage surrounding protrusions or obstructions and intractably lodge the bailer in a well casing.
