• 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 low tare weights.
• Smooth flat surface for good visibility of particles.

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.
