GE Healthcare's Whatman Puradisc Product Range

The Whatman Puradisc product range is available with a wide selection of sizes and membrane types to provide full flexibility for each application. For cold sterilization GE healthcare recommend the Puradisc sterile syringe filter with a 0.2 μm PES membrane.

The PES membrane is inherently hydrophilic, has low extractables, and exhibits low protein binding. These features allow samples to be filtered without any risk of contamination. The housing is made of pigment free polypropylene (PP) ensuring high quality sample preparation for critical applications. Cell culture additions up to 50 ml can be filtered (depending on the sample type) using the sterile Puradisc with 0.2 μm PES membrane.

GE Healthcare's Puradisc features:
•  Clean room manufacturing/production
•  Pore size 0.2 μm and 0.45 μm
•  Non sterile options available
•  Pigment-free polypropylene (polycarbonate for Puradisc 30 and Aqua 30)
•  Standard inlet and outlet luer connectors
•  Optional sterile, medical-grade blister pack
•  Choice of filter sizes (4 mm, 13 mm or 30 mm) to minimize sample loss
•  Other membrane types available

Whatman Puradisc 4 Syringe Filters
GE healthcare's Puradisc 4 Features:
•  4 mm diameter syringe filter
•  Sample volume up to 2 ml
