The Polyvinylidene Fluoride (PVDF) is a material that has great properties: high chemical and physical stability, low absorption of proteins, low level of extractables and a perfect pore structure.
Two kinds of PVDF are manufactured: with hydrophilic reaction to water and hydrophobic reaction to water.
The hydrophilic one can be used on the clarification and sterilization of aqueous and biological samples, and in the filtration of aggressive solvents, diluted, alcohols, acids, etc.
While the hydrophobic version is appropriated for the filtration of gases, vapors, and also of solvents or samples that does not have an aqueous character.
It is available in a sterile and non sterile format and in 13, 25 and 30mm of diameter, 33 mm of diameter with hydrophobic membrane.
