PTFE SYRINGE FILTERS


DESCRIPTION

    

Recommend for HPLC and GC samples, sterilisation and clarification of most solvents and filtration of gases-venting.

  • Incorporated PTFE ( polytetrafluorethylene) membrane fixed without adhesive to a polypropylene housing.
  • Hydrophobic.
  • Very high flow rate.
  • High chemical resistance to most solvents and acids.
  • Free from wetting agents.
  • They must be pre-wetted with a solvent such as ethanol or isopropanol before filtering aqueous samples.
  • The filter diameter is related to the volume to be filtered:
    • <1 ml – 4 mm
    • <5 ml – 15 mm
    • <100 ml – 25 mm
  • Pore size 0.20 µm and 0.45 µm.
  • Sterilization by autoclaving at 121 ºC and ethylene oxide.

APPLICATIONS

  • Sterilisation and clarification of most acids and aggressive solvents
  • Degassing solvents
  • Ventingof containers, and sterile air, gas and aerosol applications
  • Protection within vacuum pump
  • Cleaning of small volume samples for HPLC and GC applications, which require greater chemical resistance than regenerated cellulose syringes (JCR)
  • Excellent for sterilisation and clarification of most solvents (such as acetone, dimethyl formamide or DMSO), and of very aggressive or acidic solutions.
  • Filtration and degassing of solvents before being analysed and venting of sterile containers.
