Beschreibung

Allgemeine Beschreibung

Whatman Puradisc non-sterile syringe filters with polyethersulfone (PES) membrane combine premium quality with economic efficiency.

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.

Polyethersulfone (PES) membranes

Hydrophilic PES membranes are designed for stability in low pH, have low levels of extractables, and exhibit low protein binding, making them suitable for many aqueous and organic solvents. PES membranes allow higher liquid flow than either PTFE or PVDF.

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.

Leistungsmerkmale und Vorteile

• 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

Eignung

Suitable for filtration of biological and HPLC samples.
