- PTFE Syringe Filters
- PTFE membrane is perfect for the filtration of gaseous or organic solvent-based samples and highly corrosive substances. The hydrophobic PTFE membrane provides chemical resistance to aggressive media and excellent temperature stability allowing an extended sampling range.
- If used with aqueous samples, the membrane usually requires pre-wetting (normally by using a small amount of alcohol) but other membranes such as nylon have a better performance for these samples and are easier to use.
- PTFE syringe filters can also be used to prevent moisture passing through air vents.
