Puradisc 25mm针头式滤器GF/FWhatman Puradisc syringe filters from GE Healthcare’s Life Sciences business combine premium quality with economic efficiency. They are well suited for rapid, routine syringe filtration of samples up to 100 ml.
Puradisc syringe filters for routine syringe filtrationPuradisc syringe filters cater to a wide variety of sample types and applications, including capillary electrophoresis, biological preparations, protein filtration, and UV spectroscopy sample preparation. Different Puradisc membrane media support diverse chemical solvents and compounds. Puradisc is available in the following membrane materials: regenerated cellulose (RC), cellulose nitrate, nylon, polytetrafluoroethylene (PTFE), polyethersulfone (PES), polypropylene, polyvinylidene difluoride (PVDF), and cellulose acetate. GE’s Whatman Puradisc line is a comprehensive syringe filter portfolio used in a variety of applications. GE also offers high-performance GD/X syringe filters with a multi-layer glass fiber prefilter for filtering larger volumes of harder-to-filter samples. Glass microfiber (GMF) membranesGlass microfiber is hydrophilic and has excellent compatibility with organic solvents and strong acids (except hydrofluoric acid) and bases. However, it is not a micropore membrane and so has a slightly less exact retention efficiency than polymeric membranes. GMF can also contribute extractables that interfere with ionic and metals analysis. Looking for a filter paper, membrane filter, or syringe filter? Let GE help you find the optimal filter for your needs to ensure reliable analysis. |
