FILTERMEMBRANE FILTERPTFE-D

PTFE-D (Polytetrafluoethylene)







Supported PTFE type with polypropylene net support on a thick PTFE-type membrane filter.
   It is easy to handle it and easy to insert it into a holder.
Hydrophobic, suitable for most solvents
Thermally stable up to 145℃
PTFE-D membrane filters which have water repellency are permeable to oil or organic solvents but impermeable to water.
As hydrophobic PTFE has own water repellency, be sure to soak PTFE-D membrane filter in the proper solvents (sopropyl or ethylene alcohol) before filtration starts when aqueous solutions is filtered.
