Description

Point source sampling is ideal for obtaining high quality, representative samples of groundwater from specific depths. It allows the collection of water that has just flowed into a well at the desired sampling point. This can avoid purging and disposal of purged water.
The Solinst 429 Point Source Bailer can be used to profile an open borehole or screened well, collecting samples from distinct levels or points of inflow. Sample biases due to mixing of the sample with water from different levels in the well is minimized.

It is constructed of 316 stainless-steel with PTFE ball valves, and o-rings. The sampler comes complete with a stainless-steel sample release device to minimize loss of volatiles during transfer to the sample container.

The miniature 12.7mm diameter model is ideal for use in narrow tubes and direct push devices.
