Advantec's line of unsupported, hydrophilic, pure PTFE membranes are ideally suited for use in HPLC separations and other applications involving mixtures of aqueous and organic solvents.
Choosing PTFE as a filtration medium ensures maximum chemical compatibility, wide-ranging thermal/pH resistance, and high flow rates/minimal aqueous extractables. In addition to the durability provided by PTFE support, these membranes also offer a unique affinity for water. This dynamic integration of chemical properties facilitates optimal sample analysis and allows users to realize more efficiencies with minimal process times. With no need to pre-wet the membrane or flush pre-wetting chemicals, these hydrophilic membranes are able to maintain filtration integrity, allow optical clarity when wet, reduce interference with biological processes, and maximize shelf-life.
