Hydrophilic PVDF Filter Cartridge

MLSPVDF series filter cartridges is particularly suited for the filtration of products containing elements that can adsorb to the media, such as preservatives and proteins. The very low binding nature of PVDF makes it a good choice for filtra-tion of valuable protein solutions. It is absolute membrane filter cartridges and used for biological sterilization/clarification, and HPLC/analytical sample preparation. MLS PFH PVDF filter cartridges do not require the use of wetting agents, transmitting negligible extracta-bles increase sample purity during sterilization or clarification procedures.
