Filters are essential in research laboratories and many other industries for removing particulates and creating environments conducive to a wide array of experiments and procedures. The devices come in different forms including in-line filters, paper discs, small capsules, and large ventilation panels. Filters also purify and concentrate the liquids and gases required for testing. For air, this means removing pollution, moisture, and solid airborne particulates; for liquids, this means removing impurities and small contaminants.

Syringe filters, Minisart® CE
Supplier: Sartorius
Elimination of particles from samples prior to HPLC or other chromatographic analysis is essential in order to maintain the integrity of the chromatography column and to maximise its operating life time. Minisart® syringe filters optimised 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 1 ml to 100 ml these filters are available in three different diameters with an effective filtration area of 0,12, 1,7 and 4,8 cm².
