Spectrum® In-Line Membrane Filters

Easy-to-use, sterile and disposable, these In-Line Filters contain a polytetrafluoroethylene (PTFE) membrane. PTFE membranes are inherently hydrophobic, making these filters ideal for filtration of nonpolar liquids and gases. They are very resistant to solvents as well as acids or bases. They can be made hydrophilic by flushing with alcohol, followed by water, making them useful for filtering and de-gassing chromatography solvents.

The PTFE in-line filters have excellent chemical compatibility for filtering harsh chemicals that destroy other membrane materials. They feature a moisture barrier for venting applications and vacuum pump line protection. They are also ideal for aerosol blocking in venting and vacuum pump exhausting applications. They are able to filter viscous organic-based HPLC samples in larger volumes than what syringe filters will permit.
After pre-wetting with alcohol, they may be used for fine particle removal of aqueous and mild organic solutions in Ion Chromatography.
