Model ASCENSION -Portable Microplastics Depth Sampler

SHARE

Studies suggest that 99.8% of oceanic plastic sinks below the ocean`s surface. Until now, microplastics sampling equipment either only skimmed the water’s surface or required large and expensive research vessels with industrial deployment capabilities for below-surface sampling. Ascension is a portable and tethered instrument that collects filtered microplastic samples down to 400 m depths from the side of a small vessel or fixed installation. Filtering water directly in situ, Ascension significantly increases your sample collection capabilities and reduces contamination.
