Membrane Filters
2029 products
Showing 1993 - 2016 of 2029 products
We offer a complete range of cellulose filter papers, glass and quartz fiber filters, and membrane filters. Cellulose filter papers enable filtration of larger particles (up to 25 µm), while glass and quartz fiber filters combine fast flow rates, high loading capacities, and retention of very fine particles (0.7 to 2.7 µm). Membrane filters are recommended for retention of very small particles or for microbiological purposes. Our membrane filter offering includes pore sizes from 0.015 to 12 µm.
Whatman filter papers and membranes are world-renowned as a standard for laboratory filtration and are associated with quality, reliability, and reproducibility. Flat filters are widely used for general sample filtration in various fields such as quality control, environmental monitoring, and research. Sample filtration is usually either for particle removal or for particle/precipitate collection prior to analysis.
