Pura Disc 13mm GF/F GMF Syringe Filters, 0.7um, 100/Pk
Whatman SKU: 6825-1307

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 0.7 µm, 13 mm, 100/Pk - 6825-1307

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. At the point of sample preparation, a syringe filter removes particulates before the sample reaches the instrument. Inorganic glass fiber offers broad chemical compatibility for demanding samples and wets rapidly with aqueous samples. The polypropylene housing resists aqueous acids, bases, and alcohols while maintaining a low-dead-volume internal flow path and contributes minimal extractables to the filtrate. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.
