Filter Paper, Membrane Filters
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.
Sample Collection Cards & Kits
We offer a large variety of products to meet your requirements for sample collection, transportation, and storage. Our Whatman FTA/FTA Elute cards provide simple solutions to collect, preserve, and purify biological samples at room temperature for downstream DNA analysis. FTA DMPK-A, FTA DMPK-B, and FTA DMPK-C cards are ideal media for dried blood spot (DBS) microvolume sampling and are widely used in drug metabolism (DM), pharmacokinetic (PK), and toxicokinetic (TK) studies. 903 cards have a long history in blood spot sampling for screening programmes.
Convenient collection products and reliable solutions for transportation and preservation of biological samples are essential in a wide range of forensic, pharmaceutical, biotechnological, research, and screening applications. Biological samples include for examples blood, buccal, tissue, plant, and cultured cell samples as well as microorganisms. DNA and other biomolecules collected with these products may, after simple purification steps, be used for many types of downstream analyses.
