ABSTRACT:
An improved bailer which allows for the variance of flow into the bailer through use of attachments with varying inflow orifice sizes. As the size of the orifice changes, the weight of the apparatus can also be changed allowing for an only slightly negative buoyancy of the apparatus. The attachment may also be designed to include features for filtering unwanted particulates from the sample.
