IW Tremont Syringe Filters have a Luer-Lok Connector inlet with luer-slip outlet. Disposable. Ultrasonically bonded for reliability. Filter media type is clearly inscribed on barrel. High purity virgin polypropylene housing, no dyes or pigments added. Unique concentric funnel shaped barrel increases volume and decreases back pressure.
Polytetrafluoroethylene PTFE membranes are forced to be hydrophilic by flushing with alcohol, followed by water; ideal for the filtration of nonpolar liquids and gases. Very resistant to solvents as well as acids or bases. Used for filtering and de-gassing chromatography solvents. Permits optimal utilization of small sample volumes. Excellent chemical compatibility for filtering harsh chemicals that destroy other membrane materials. Moisture barrier for venting applications and vacuum pump line protection. Ideal for aerosol sampling. Filter viscous organic based HPLC samples. After pre-wetting with alcohol, may be used for fine particle removal of aqueous and mild organic solutions in Ion Chromatography.
