Narrow pore size distribution for improved surface capture and analysis. Low levels of extractables to ensure sample integrity. Cellulose nitrate membranes, circles, plain Whatman membrane filters, including very narrow pore size distribution and low levels of extractables. Recommended for the majority of routine applications, this membrane is manufactured under strictly controlled conditions. The user will benefit from the performance improvements that are now available in Whatman membrane filters, including very narrow pore size distribution and low levels of extractables improved flexibility and are made to tolerate abuse during handling, loading, and autoclaving without sacrificing integrity. These membranes are among the strongest of their type available, as measured and compared by burst pressure tests.
