Filters Membrane 3um 47mm CN Pk 100

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 rrow pore size distribution and low levels of extractables. Most membranes are inherently brittle and difficult to handle; it is not uncommon for Filters to be damaged during loading into holders or while in use. Whatman cellulose nitrate membrane Filters have a noticeably 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. The level of extractables in membrane Filters has become more important with advances in filtration or adsorption techniques. In particular, pharmaceutical, immunological, and biomedical tissue culture and trace analysis applications can be adversely affected by high extractable levels. Whatman cellulose nitrate membrane Filters have a low level of extractables, generally below that of other membranes of a similar type.
