PTFE Spritzenvorsatzfilter

Recommended for HPLC and GC samples, sterilisation and clarification of most solvents and filtration of gases and for air venting. 

 

  • Polytetrafluorethylene (PTFE, Teflon)- Membrane, hydrophobic
  • Very high flow rate
  • High chmical ressitance to most solvents and acids
  • low hold up volume
  • Free from wetting agents
  • They must be pre-wetted with a polar solvent such as ethanol or isopropanol before filtering aqueous samples 
  • Pore size 0.2 and 0.45 μm.
  • Membrane diameters 13 mm, 25 mm und 30 mm.
