Elimination of particles from your samples prior to HPLC or other chromatographic analysis is essential in order to maintain the integrity of your chromatography column and to maximize its operating life time. Minisart® syringe filters optimized for sample preparation consist of a polypropylene (PP) housing and membrane components featuring maximum chemical compatibility and minimum extractables to ensure excellent results. Due to the typical range of volumes from less than 1ml to 100ml these filters are available in three different diameters with an effective filtration area of 0.12 cm², 1.7 cm² and 4.8 cm²
