1.:Hydrophilic Membrane


2.Size:25mm 0.22um


  • Higher Throughput : PTFE membrance + PP pre-filter provides two times greater throughput than standard filter without pre-filtration
  • PTFE membranes are chemically resistant to nearly all solvents, acids and bases. The membrane has low extractable and good thermal stability
  • Applications: Filtration of aggressive organic or highly basic solutions, transducer protectors
  • Don’t use with: Aqueous samples without prewetting (causes high backpressure)
  • Note: Kindly reminder our syringe filters are for Lab Use Only


Product Description

SYRINGE FILTER

BENEFITS

  • Adding a syringe filtration step prior to injection not only helps to ensure more consistent and reliable results
  • Helps protect delicate instruments and prolongs column life
  • Syringe Filters provide cleaner sample extracts by removing interfering materials and fine particles
  • Moisture barrier for venting applications and vacuum pump line protection

Polytetrafluoroethylene (PTFE)

Perfect for the filtration of gaseous or organic solvent-based samples and highly corrosive substances.· If used with aqueous samples, the membrane usually requires pre-wetting (normally by using a small amount of alcohol). Can also be used to prevent moisture passing through air vents. pH range ~1-14.

APPLICATION: Filtration of aggressive organic or highly basic solutions, transducer protectors.
