Whatman Sterile Cellulose Nitrate Membrane Filters

Sterile membrane filters for sample preparation

GE’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.

Low extractable level minimizes sample contamination

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.
