Hydrophilic PTFE：

By promoting hydrophilic PTFE filter film’s affinity with water, it is easier to let hydrone in organic solvent to be adsorbed and be dissolved for into and pass through the film fastly. Usually, molecular diffsuion has close relationship to the structure of film. More meticulous the film is, it can make bigger obstruction when big molecular throughing the film, but also is good for small molecular to diffuse. For water, using hydrophilic PTFE filter film is better then ordinary PTFE filter film.
