NUC PC 90MM 0.4uM 25/PK
Nuclepore track-etched polycarbonate membranes are manufactured from high-quality polycarbonate film and have sharply defined pore sizes, high flow rates, and excellent chemical and thermal resistance. The membranes have a smooth flat surface and exhibit very low levels of extractables. Low protein binding and low extractables ensuring no sample contamination.High chemical resistance and good thermal stability for a wide range of samples.Low, consistent ash and tare weights.Smooth flat surface for good visibility of particles.
