DIAFIL PVDF Syringe filters
Membrane material: Polyvinylidenfluoride
The polyvinylidenfluoride is used in many applications for biological samples (low protein adsorption) or for pharmaceutical applications. Due to its hydrophilic properties, it is used for clear filtration and sterilisation of aqueous solutions. Because of its chemical compatibility (compatibility list) it is less suitable for the filtration of aggressive media such as strong acids, bases and ketones.
DIAFIL PVDF is available in various filter diameters and pore sizes, with and without preliminary filter and as a sterile version:
