PTFE-D syringe filters which have water repellency are permeable to oil or
organic solvents and are never permeable
to water. They are not biodeteriorated or transmutated in a wide range of conditions and
not affected by ultraviolet rays
(available for autoclave) Due to low friction, they have non-adhesion and detachability. It is easy to
remove residue after filtration. Since the filter is hydrophobic, it can be used as an air vent filter. Two types in pore size : 0.2μm and 0.45μm, Filter size : 13mm and 25mm

Hydrophobic PTFE has water repellency.
When you filter aqueous solution, be sure to soak PTFE
Syringe filter in proper solvents (isopropyl alcohol or ethylene
alcohol) before starting filtration.
