General description
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.
Nylon membrane filter options
Nylon membrane filters are hydrophilic, flexible, tear-resistant, and autoclavable. They are resistant to a range of organic solvents and suitable for use with high pH samples. Nylon binds proteins, which makes it unsuitable for protein recovery applications.
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.
Features and Benefits
- Eight different material options
- Choice of 4 mm, 13 mm, and 30 mm syringe filter diameter to suit sample volume
- Range of pore sizes for retaining a variety of particles
- Optional sterile, medical-grade blister pack
- Optional tube-tip format for accurate dispensing into a micro-vial
