Whatman SPARTAN syringe filters from Cytiva provide reproducible filtration for ultra-high performance liquid chromatography (UHPLC) and high performance liquid chromatography (HPLC) sample preparation and analysis.Hydrophilic membrane made of regenerated cellulose fiber exhibits low protein binding membraneDisposable filter unit with polypropylene housingExcellent chemical resistance to common aqueous and organic solvents, so recommended for HPLC method sample preparationTested and certified for the absence of UV-absorbing substances at wavelengths of 210 and 254 nm with water, methanol, and acetonitrileDocumented batch-to-batch quality and consistency, ensuring reproducible resultsLow dead volume Mini-tip optionCertificates of Analysis (CofA) are available by searching by Lot number in certificates search.Recyclable after use. Learn how you can recycle it.SPARTAN HPLC filter for organic and aqueous sample preparationHPLC sample preparation often requires a filtration step before samples can be used for liquid column chromatography. This step helps to clarify peaks of chemical compounds being analyzed and protects the HPLC column from large particles that might damage it.SPARTAN regenerated cellulose filters from Cytiva's business cater to this need, because their regenerated cellulose hydrophilic membrane is resistant to common HPLC grade solvents and exhibits very low levels of extractables that could otherwise interfere with chromatographic analysis.In addition to their use as HPLC syringe filters, SPARTAN filters can be used in capillary gel electrophoresis, protein sample ultrafiltration, UV/VIS analysis, and any application requiring a chemically resistant, low protein binding, hydrophilic membrane in a polycarbonate filter housing.
