Product Description
When samples are viscous or protein-rich, a stainless steel screen keeps flow moving where a glass frit might clog. This 47 mm filtration assembly is built for those demanding liquids and for producing ultraclean filtrate, using a stainless steel support screen beneath the membrane.
