Syringe filtersSyringe filtersSyringe filters, labeled, CHROMAFIL Xtra PVDF, 25 mm, 0.45 µm



Inside the syringe filter polyvinylidene difluoride is used as membrane material. The hydrophilic PVDF membrane is suitable for filtration of 100 % aqueous samples, water-soluble oligomers and polymers like proteins. Extremely low binding capacity for proteins. Labeled for method validation and certification. All CHROMAFIL filters are autoclavable (121 °C and 1.1 bar for 30 min)!
