The Large Volume Water Transfer System (WTS-LV) is a large volume single-event sampler that collects suspended and dissolved particulate samples in situ into a 142mm membrane filter. The WTS-LV allows for a choice of pump size and filter porosity for a range of specimen collection. Collection targets include chlorophyll maximum, particulate trace metals, and phytoplankton.

The WTS-LV dynamic pump speed algorithm adjusts as material accumulates on the filter minimizing risk of a damaged sample and improving battery endurance. The modular filter holder is designed to evenly distribute collected material. A three-tiered filter holder option is also available.

The WTS-LV is available in four different configurations: Standard, Upright, Bore Hole, and Dual Filter Sampler.  A high capacity upright WTS-LV model provides three times the battery life of the standard model. The Bore-Hole WTS-LV is designed to fit through a narrow opening such as a 30cm bore-hole. The WTS-LVDF features two vertical intake 142 mm filter holders to allow simultaneous filtering using two different porosities.
