Stainless steel and has dual ball valves, top and bottom- this prevents a sample collected at a discrete depth from mixing with water from other depths during retrieval. Purging and disposal of purge water can be avoided. The miniature 0.5″ (12.7 mm) diameter model is ideal for use in narrow tubes and direct-push devices. Can be used to profile an open borehole or screened well, collecting samples from distinct levels or points of inflow.
