The Large Volume Water Transfer System (WTS-LV) collects a single suspended particulate sample in situ onto 142mm filter media. Collection studies include particulate trace metals and hydrothermal vent sampling. Flow rates and filter porosity support a range of specimen collection needs. Up to 45,000L of seawater can be pumped and filtered (high capacity model).

• Maximum depth: 5,500m (Standard and Bore Hole models)
(5,000m Dual Filter and High Capacity models).
• Number of samples: Single event sampler.
•Models: Standard system, Dual Filter (separately metered, modular 142mm vertical intake filter holders for parallel filtration), High Capacity (30Ah high capacity battery for 3 times the battery power), Bore Hole (configured to fit through a 30cm hole in the ice).
• Options: 4L/min, 8L/min or 30L/min pump heads, 3-tier filter holder for an additional level of pre-filtering, 293mm filter holder, trigger start (time synchronizes multiple samplers) and vertical intake filter holder.
