Pura Disc 13mm PVDF Syringe Filters, 0.2um, 100/Pk
Whatman SKU: 6779-1302

Whatman Puradisc PVDF Syringe Filters, 0.2 µm, 13 mm, 100/Pk - 6779-1302

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Hydrophilic PVDF wets aqueous and HPLC samples on contact and minimizes protein binding for high analyte recovery. Polypropylene construction maintains a low-dead-volume internal flow path while holding a reliable seal against the membrane edge and keeps the fluid path low in extractable contamination. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Resists HPLC mobile phases, alcohols, and mild hydrocarbons
