PTFE syringe filters are perfect for the filtration of gaseous or organic solvent-based samples. The hydrophobic PTFE membrane provides broad chemical resistance and excellent temperature stability giving an extended sampling range. PTFE filters may also be used as a moisture barrier in venting applications.
If used with aqueous samples, the membrane usually requires pre-wetting (normally by using a small amount of alcohol).
Ideal for use with sample volumes of <10ml
Retention Volume: <20ul
