Syringe Filters, Laboratory Filtration Products

Our syringe filters feature a polypropylene housing that are ultrasonically bonded for reliability. These syringe filters have a leur-lok and pressure fitting and come in a broad range of filter material. Compare our sterile and non-sterile syringe filters to name brands such as Pall* Acrodisc* and Whatman Puradisc*. Polyvinylidene Difuoride (PVDF) - Hydrophobic • This membrane features a stability and hydrophobic interactions simlar to PTFE. • Recommended especially for filtration of water-soluble oligomers and polymers, e.g. protein solutions. • Can also be used for the filtration of hydrophobic substances in diferent organic solvents. Polytetrafluoroethylene (PTFE) - Hydrophilic or Hydrophobic • 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 application and vacuum pump line protection. • Ideal for aerosol sampling. • Filter viscous organic based HPLC samples. • Glass microfiber prefilter raises absorption capacity and loading. • After pre-wetting with alcohol, may be used for fine particle removal of aqueous and mild organic solution in Ion Chromatography. Nylon Nylon syringe filters are designed for sterilization or clarification of aqueous and solvent samples in a wide array of analytical and research applications. It is primarily used to filter small aqueous and organic samples with low hold-up volume in order to inject them directly into the HPLC sample loop systems. The filtered samples ensure column protection. HPLC certified. Polyethersulfone (PES) - Hydrophilic • High filtration flow rates. • An inherently low affinity for proteins. • Low extractables. • Introduction of additives into tissue culture vessel. • Certified for Ion Chromatography. • Final filtration of bacteriophage and infusion solutions. • Tissue culture, proteins, bufer and nucleic acids filtration. • Ideal for applications requiring maximum sample recovery. • Filter hybridization solutions and probe to reduce backgrounds. • Food, beverages and ultra purewater final filtration. Cellulose Acetate (CA) - Hydrophilic • Very low binding capacity for proteins. • Material is nitrate-free making it suitable for groundwater & EPA ASTM's. • For filtation under sterile conditions. • Filtration and clarification of biological fluids, sterilization of media additives and serum. • Sample preparation of aqueous solutions. • Designed to sterilize and remove particulates from even the most viscous proteinaceous samples. • Filtration of tissues culture media with glass fiber prefilter. Mixed Cellulose Esters (MCE) - Hydrophilic • This membrane is recommended for all filtrations in aqueous or polar media, bacteria filtration. • Ideal when maximum protein recovery in filtrate is crucial. • Used for filtration and inspection of gas, oil and alcohol particulate and bacteria. • Combined wit glass microfiber prefilter, ideal for tissue culture media and sensitive biological samples • Sample fitration - prefilter increases yield. Glass Fiber (GF) For prefiltering heavily contaminated aqueous or solvent based samples. Filters are made of 100% binder-free borosilicate glass fiber. Polypropylene (PP) Polypropylene syringe filter is designed to filter gas and organic solvent-based samples in a wide array of analytical and research application. These units are recommended for ion chromatography, HPLC sample preparation and critical low detection levels <230nm.
