Munktell Polycarbonate membrane filters:
Polycarbonate Membrane Filters are hydrophilic. They are produced from a highly pure polycarbonate film using nuclear radiation.They have a very uniform pore structure and a narrow pore size distribution. Thanks to their very low halogen values they are suitable for AOX analysis acc. DIN and ASTM.
Thermally stable up to 140°C
