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)!
