Recommended for microbiological culturing and sample preparation, Cytiva's Whatman cellulose nitrate membrane filters offer very narrow pore size distribution and low levels of extractables.
Sterile membrane filters eliminate the risk of contamination that could impact analysis
Narrow pore size distribution for improved surface capture and analysis
Low levels of extractables to ensure sample integrity.
Sterile membrane filters for sample preparation
Cytiva's cellulose nitrate sterile membrane filters are well suited for separation applications involving particles up to 12 µm. After sample preparation, filtration residue is almost completely retained by the plain white membrane surface, supporting clear microscopy and physical recovery of deposits.
High strength and flexibility preserves membrane integrity
Most membranes are inherently brittle and difficult to handle; some may be damaged as they are loaded into holders or during standard use. Whatman cellulose nitrate membrane filters are designed to tolerate rough handling.
Pharmaceutical, immunological, biomedical tissue culture, and trace analysis applications rely on knowing that filtration preserves the integrity of the original sample. Because Whatman cellulose nitrate membrane filters have a low level of extractables, they are a good choice for sample preparation of critical samples.
