Unique raised column structure with 0.45μm PES membrane processes double sample volume vs conventional filters, extending service life.
Ensuring peak purity in liquid chromatography begins with effective sample preparation. The 0.45µm PTFE syringe filter is the industry standard for clarifying samples containing aggressive organic solvents. Designed for compatibility with chemically harsh matrices, these filters prevent column blockage and protect your HPLC instrumentation from particulate damage.
13mm diameter syringe filter: Filter Ø: 13 mm Filtration area: 1.09 mm2 Housing material: polypropylene Holdup volume: <20 µl Sample volume: <10 ml Maximum Operating Temperature: 130°C (Housing only, also dependent on membrane) Maximum Operating Pressure: 87 psi (Housing only, also dependent on the membrane) Inlet: Luer locks female Outlet: Luer slipped male
PTFE membranes are inherently hydrophobic; they are ideal for the filtration of nonpolar liquids and gases. Very resistant to solvents as well as acids or bases. Can be made more hydrophilic by flushing with alcohol, followed by water 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
The syringe filter produced by Aijiren is often used to filter impurities in the reagents to be tested. After the impurities are filtered, the reagents can be sucked into the autosampler. If the syringe filter is not used, it may cause problems such as clogging the needle hole with impurities in the reagent.
Lab-grade syringe filters engineered for HPLC and MS analysis, available in Nylon, Hydrophilic PVDF, PTFE, and more. Features low extractables and ISO-certified biocompatibility for sample integrity and instrument protection.
