Puradisc syringe filters for routine syringe filtration
Puradisc 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.
Whatman Puradisc line is a comprehensive syringe filter portfolio used in a variety of applications. We also offer high-performance GD/X syringe filters with a multi-layer glass fiber prefilter for filtering larger volumes of harder-to-filter samples.
Cellulose nitrate membrane filters
Cellulose nitrate membranes have high mechanical strength, high flexibility, high flow rates, and low extractable levels. These features make the membrane a good choice for trace element analysis applications. However, they also exhibit high protein binding so are unsuitable for protein recovery applications.
