Nuclepore polycarbonate filters contain uniform, cylindrical pores, preferentially etched into the membrane, allowing for an even distribution of a collected sample in one plane across the entire exposed membrane surface. Contaminant-free, these microporous screens are biologically inert, and offer excellent chemical resistance and thermal stability.
