Difference between hydrophilic and hydrophobic filters
Once wetted, hydrophilic filters do not allow the free passage of gases until the applied pressure exceeds the bubble point and the liquid is expelled from the pores of the membrane. Hydrophobic filters will not wet in water but will wet in low surface tension liquids, for example, organic solvents such as alcohols. Once a hydrophobic filter
Hydrophilic Ptfe at Thomas Scientific
Hydrophilic PTFE syringe filters have broad chemical compatibility and high pH resistance and are optically clear when wet with water. They are versatile filters for use with aqueous and aggressive organic solvent-based solutions and are especially ideal for HPLC sample preparation.
Laboratory Filters | Filtration Products | Waters
The minispike outlet, available on 13 mm PTFE, Nylon, GH Polypro, and PVDF Acrodisc Syringe Filters, allows for easy dispensing into autosampler vials. Membrane Design Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see table below for a full selection of mebranes).
Fluoropore Membrane Filter | FHUP04700
Fluoropore™ membranes provide broad chemical compatibility, high flow rates and consistency. (Please note that catalogue numbers containing "FHUP" are unlaminated, or produced without a backing.) Our Omnipore™ membrane is a hydrophilic PTFE membrane that is compatible with virually all solvents, acids, and alkaline solutions. Features
Membrane Filtration | Membrane Filters | Sartorius
The main application of these membrane filters is the filtration of air, gases or chemicals. Unlike other (hydrophilic) filter types, they are not wetted by air humidity, allowing unhindered passage of air at low differential pressures as well. PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also

Filters in Dissolution Testing: Evaluation and Selection
When the hydrophilic PTFE membrane from vendor A (0.2 and 0.45 µm) were compared with polypropylene membranes from vendor B (same size), an increase in back pressure was observed for the mobile phase filtered through the polypropylene membrane (1500–2000 PSI). The hydrophilic PTFE membrane retained particles quantitatively; no increase
